Full textAbstract:
The global marketplace is highly competitive and organisations who want to survive long-term, have to continuously improve, change and adapt in response to market demands. Improvements in a company's performance should focus on cost cutting, increasing productivity levels, quality and guaranteeing deliveries in order to satisfy customers. Total Productive Maintenance (TPM) is one method, which can be used to achieve these goals. TPM is an approach to equipment management that involves employees from both production and maintenance departments. Its purpose is to eliminate major production losses by introducing a program of continuous and systematic improvements to production equipment. TPM should be developed and expanded to embrace the whole organisation and all employees should be involved in the process as members of improvement teams. This thesis describes the development of TPM and the TPM implementation process. Research is focused on the implementation process of TPM. The author has had the opportunity of both monitoring and steering a company through part of its TPM implementation program and has conducted a longitudinal study. The implementation process takes several years and this thesis focuses on the initial three years of the process. This study demonstrates that driving forces, obstacles and difficulties often are dependent on the organisation, its managers and the individual employees. It also shows that the TPM implementation process has many similarities to the implementation of other improvement concepts. The analysis of these findings forms the basis for recommendations and guidance for organisations, who intend to implement TPM.Godkänd; 2000; 20070318 (ysko)

Full textAbstract:
A growing uncertainty in the global economy is forcing many manufacturers to reassess their corporate outlook towards the environment. Today there is a growing attention to sustainability in industry accompanied by a paradigm shift towards realizing a sustainable society. It is now very common to hear about Green Production and Green Systems, but few literature exist that deal with the relatively newer subject of Green Maintenance. The term green production is often used to describe production with a sustainable perspective. Also, lean production has been proposed as a means of achieving sustainability. Lean and Green production systems require efficient production and low use of resources such as energy, materials, etc. One major facilitator of this is effective maintenance. Sometimes regarded as the necessary evil, maintenance still has a negative image in the industry. But as the paradigm on manufacturing shift towards realizing a sustainable society, we should also begin to realize the changing role of maintenance. Still, the impact of maintenance on sustainability and Green production is not very well described in research. This Master Thesis within the School of Innovation Design and Engineering at Mälardalen University presents a literature review on green maintenance by trying to identify and assess the key factors of maintenance effects on green production, life cycle assessment and sustainability of maintenance activities. In addition, a brief introduction to the greening of remanufacturing activity, part of a green process by itself, is provided. The research is based upon extensive literature study, questionnaire survey and interviews with relevant industry as well as academic personnel. A discussion of the results of the interview followed by a conclusion on the key factors of maintenance on sustainability is provided. Future research areas have also been suggested.

Total Productive Maintenance (TPM), recently interests many major industrial companies, for the need to maintain the physical assets and the continuity of work. According to the Japan Institute of Plant Maintenance (JIMP), the (TPM) is based on eight principles: focused improvement, autonomous maintenance, planned maintenance, training and skills development, initial phase management, quality maintenance, TPM in Office, and safety environment. Through the implementation of those principles, an increased productivity can be achieved by reducing faults, improving quality, delivering times when specified, improving working conditions and raising the morale of the workers. This Research focused on factors and obstacles that effect this program. The research aims to design a framework that identifies the most important factors that affect the success of the application of TPM, as well as the tools and techniques that help in the application process. To determine the factors and obstacles when applying TPM, Libyan Iron and Steel Company LISCO has been selected as case study. This study analyzed impediments and obstacles to the implementation procedure and revealed key success ranked factors concluding with a conceptual framework for a successful TPM implementation along with the identification of tools and techniques to support implementing TPM. Also, TPM cannot be applied unless there is cooperation and coordination between the maintenance department and other sections of the company. Accordingly, this research also provided several recommendations, including the application of the concepts and principles of TPM in the company and make it the responsibility of everyone, and work in light of the proposed improvement plan.

Full textAbstract:
Productive Plants Maintenance is a strategic function of industrial realities that aims to ensure the regular functioning and good conservation of productive equipment. (OSCE, 1993); in particular, it comprehends all technical and administrative techniques, including controlling activities, that aim to restore to and/or maintain an item in a condition in which it can performed the required function (UNI9910). A company, at in a first moment, decides to invest a part of its capital in new equipment for production, to reach its core business goals and gains success; in a second moment, anyway, it is necessary to invest resources and time to guarantee its correct functioning and conservation, to satisfy the productive expectation (Pay Back).
TPM (Total Productive Maintenance) is an industrial tool that comprehends all techniques and methods that aim to optimize industrial plants effectiveness, through equipment availability improvement and making downtime and failure decrease. TPM paradigm aims to increase productivity (Productive), involving all the staff (Total), through maintenance (Maintenance). TPM benefits are well known in our industries: companies that applied these techniques registered a reduction of failures of about 50%, a reduction of production loss of about 70%, the 60% of reduction of maintenance costs and, finally, 50-90% of reduction in set-up time.
However its implementation in industrial realities it is not always so easy: it is necessary to take care to some critical factors that might influence the success of the project. In the world of automatic production systems, where the human factor is reduced and often useless, to involve people in equipment maintenance might be hard. Moreover, to align production and maintenance requirements, in order to optimize equipment availability, means to plan together production downtime, looking to satisfy the demand that is becoming more and more variable and uncertain, with shortest lead time.
In this context, this work aims to carry out a useful framework to apply TPM in automatic production systems, in particular in Food & Beverage sector, focusing on the drivers that might influence its implementation. Food Industry, in addition to peculiarities related to the automation world, is characterized by factors related to security, safety, quality and sustainability. From literature review about many case studies of TPM Implementation it arises that the application of this paradigm on industrial realities requires a very long time and a lot of resources, and its benefits are slowly to arise. What is proposed in this work is different in the way it aims to maximize and to highlight TPM benefits in a faster way; the framework, in particular, is focused on carrying out productive equipment criticalities, through the use of various tools and techniques, to optimize and arise results. Therefore, it is propose the application of the framework to a real industrial case.
Then, a second part of this work is dedicated to micro downtime analysis in automatic production flow lines. In fact, as it arises from the case study, micro downtime is the greatest cause of inefficiency in these production systems. Micro downtime can be related to technical and/or design causes, or to the normal functioning of more machines working in series with different characteristics. Sometime micro downtime inefficiency could be solved with technical solutions, if they result convenient (efficiency
improvement compared to the investment proposed); in other cases it is required to evaluate the buffer size and allocation. In fact, in this sector, machines downtime might be related to lack of product in ingress ( the upstream machine is down – starving) or the excess of product in exit (the downstream machine is down – blocked).
The Ph.D. thesis structure is the follow:
1. State of the art analysis about factors that influence TPM implementation in automatic production systems and about food and beverage sector peculiarities; the core objective is to identify an innovative and structured framework for TPM implementation; what is new in the proposed framework is the focus on accelerated and visible benefits.
2. TPM framework application to a real industrial case, in particular a bottling line. During the framework implementation, micro downtime arise as the core inefficiency.
3. State of the art analysis about Downtime in automatic production systems, focusing on micro downtime impact on production efficiency and machines availability. Improvement for these inefficiencies are proposed as: technical solutions related to the improvement of equipment effectiveness (CPI – Cost Performance Indicator) or evaluation of buffer sizing and location through a simulative model (BAP – Buffer Allocation Problem);
4. Micro downtime analysis applied to a real case study; construction of the CPI, when possible, and of a new simulative model to evaluate buffer sizing and allocation. It is proposed a new simulative model based on ad hoc micro downtime probability distribution (Weibull Distribution for each micro downtime).
This Ph.D. Thesis has been carries out in strong collaboration with Acqua Minerale San Benedetto S.p.A., that made possible the framework implementation and data collection.La Manutenzione degli Impianti Produttivi è una funzione strategica delle realtà industriali che ha l’obiettivo di assicurare il funzionamento regolare ed il buono stato di conservazione di questi sistemi (OSCE, 1993); in particolare, secondo la definizione UNI9910, essa comprende tutte le azioni tecniche ed amministrative, incluse le azioni di supervisione, volte a mantenere o a riportare un’entità in uno stato in cui possa eseguire la funzione richiesta. Se inizialmente un’azienda decide di investire una parte del proprio capitale nella costruzione ed avviamento di un nuovo impianto produttivo, successivamente è necessario investire tempo e risorse per il suo mantenimento, al fine di mantenere i requisiti richiesti e soddisfare le aspettative (Pay Back). Il TPM (Total Productive Maintenance) consiste in un insieme di tecniche e strumenti che hanno la funzione di ottimizzare il mantenimento degli impianti produttivi, aumentandone l’affidabilità e riducendo fermi e guasti. Il TPM mira ad aumentare la produttività degli impianti (Productive), coinvolgendo tutto il personale (Total), attraverso la manutenzione (Maintenance). I benefici del TPM sono ormai ben noti nelle industrie: le aziende che hanno implementato tale paradigma hanno registrato una riduzione dei guasti del 50%, del 70% di produzione persa, del 60 % dei costi di manutenzione e tra il 50-90% dei tempi di set-up. Tuttavia la sua implementazione non è sempre facile e diretta: è necessario porre attenzione ad alcuni fattori che possono pesantemente incidere sul successo del progetto. Per quanto riguarda il mondo degli impianti automatizzati, dove il fattore umano è ridotto e spesso estraneo, coinvolgere il personale nel mantenimento delle macchine può risultare difficoltoso. L’obiettivo di allineare esigenze produttive e manutentive, nell’ottica di ottimizzare l’affidabilità degli impianti, implica concordare fermi produttivi rispettando tempi di consegna sempre più ristretti con previsioni della domanda estremamente variabili; pertanto risulta evidente come ottimizzare la produzione attraverso la manutenzione possa essere un obiettivo ambizioso nelle realtà industriali. In tale contesto si inserisce la presente trattazione, che ha l’obiettivo di proporre un framework di applicazione di tecniche di manutenzione nel contesto degli impianti automatizzati, in particolare legato al mondo del Food & Beverage. Tale settore, oltre alle peculiarità legate al mondo automatizzato, è caratterizzato da fattori di sicurezza alimentare, elevata qualità e obiettivi a sfondo ecosostenibile. Da quanto emerso in letteratura, il processo di applicazione del TPM è lungo ed impegnativo, e spesso i suoi benefici richiedono lunghi periodi per diventare tangibili. Quanto proposto in questo lavoro si differenzia dall’attuale stato dell’arte in quanto ambisce a massimizzare ed evidenziare i benefici di tale paradigma in tempi più ristretti; il framework proposto, in particolare, mira a focalizzarsi sulle criticità degli impianti produttivi, proponendo varie tecniche risolutive al fine di massimizzare i risultati e aumentarne la visibilità. E’ poi proposta l’applicazione di tale framework ad una vera realtà industriale, quale una linea di imbottigliamento. Una seconda parte di tale lavoro è dedicata, invece, all’analisi delle micro fermate negli impianti automatizzati. Infatti, come emerso anche dal caso studio, esse rappresentano una rilevante fonte di inefficienza negli impianti automatizzati. Le microfermate possono essere di natura tecnica e/o di progetto oppure legate al normale funzionamento di più macchine con caratteristiche differenti che lavorano in sequenza. Tale inefficienza talvolta può essere risolta con soluzioni tecniche mirate e definitive, se opportunamente convenienti (recupero efficienza rispetto investimento proposto); talvolta invece è richiesta una rivalutazione del dimensionamento del Buffer tra le due stazioni di lavoro al fine di ridurre l’incisività delle micro fermate di una macchina sull’intera linea (fenomeni di starving and blocking). Nelle linee automatizzate è frequente che una macchina si trovi nelle condizioni di non poter operare per mancanza di input (starving) o per eccesso di output (blocking). La tesi è suddivisa in quattro fasi: 1. Analisi dello stato dell’arte dei fattori che hanno influenzato l’implementazione della TPM nei sistemi automatizzati e delle peculiarità dell’industria alimentare al fine di identificare un modello di implementazione strutturato ed innovativo; la differenza dallo stato attuale è il focus su risultati accelerati e visibili. 2. Applicazione del modello ad un impianto di imbottigliamento; individuazione delle micro fermate come causa impattante di inefficienza produttiva. 3. Analisi dello stato dell’arte sui Downtime negli impianti automatizzati, focalizzandosi sull’impatto delle micro fermate sull’efficienza produttiva ed affidabilità del sistema. Proposte di miglioramento di tali inefficienze: Soluzione tecniche mirate con modello di recupero di efficienza produttiva (CPI – Cost Performance Indicator) o rivalutazione del dimensionamento dei buffer (BAP – Buffer Allocation Problem). 4. Analisi mirata delle micro fermate di una stazione di lavoro critica e relativa costruzione del modello simulativo per valutare il dimensionamento di un buffer. Tale modello risulta innovativo in quanto è basato su distribuzioni di Weibull personalizzate per ogni tipologia di micro fermata. Tale progetto di ricerca è stato svolto grazie alla collaborazione con Acqua Minerale San Benedetto S.p.A., che ha reso possibile l’implementazione del modello e la raccolta dei dati.

Full textAbstract:
The study improved the overall equipment effectiveness (OEE) of machines and processes through the implementation of a total productive maintenance (TPM) approach at Company S over a three-month period. By comparing the OEE of equipment before and after the implementation of autonomous maintenance, this study concluded that autonomous maintenance improves OEE. The target of this study was one general product line at a polytetrafluoroethylene (PTFE) plant. Due to time limitations, the study only applied autonomous maintenance to operational activities. This research involved machine and processes selection, condition assessment, baseline OEE assessment, operator training, execution of autonomous maintenance, and OEE measurement. The approach was based on the steps of autonomous maintenance but was simplified for the conditions of the plant.

Mestrado em Gestão e Estratégia IndustrialNuma economia globalizada, a competitividade dita a necessidade de redução dos custos nos processos produtivos. Para essa finalidade, existem diversas ferramentas de gestão que respondem à necessidade crescente de redução de custos e melhoria contínua, com o objectivo de aumentar a produtividade. O TPM, i.e., Total Productive Maintenance, assume-se como uma abordagem à gestão dos equipamentos que procura a maximização da eficiência global dos mesmos, através da redução das perdas associadas ao processo produtivo, envolvendo directamente todos os colaboradores da empresa. No entanto, implementação sem critério desta filosofia tem-se traduzido em situações de fracasso e descrédito por parte dos colaboradores. Este trabalho visa propor uma metodologia que contrarie esta situação, conduzindo os responsáveis da empresa por uma sequência de etapas que estabeleçam as condições para a implementação do TPM bem sucedida. A metodologia proposta é validada através da elaboração de um projecto-piloto dedicado à linha da embalagem de uma fábrica de cimento demonstrando ser capaz de criar as condições propícias à implementação do TPM de uma forma consistente. Os resultados prevêem uma redução dos gastos com a manutenção, pela transferência de tarefas para os operadores e o aumento de produtividade decorrente da diminuição das paragens. É expectável uma melhoria real do OEE (Overall Equipment Efficiency) de 21% relativamente ao nível actual. Mais do que a obtenção de resultados tangíveis, o maior ganho com a implementação da metodologia proposta será a mudança cultural despoletada pelo projecto.
In a globalized economy, competition dictates the need to reduce costs in production processes. For this purpose, with the aim of increasing productivity, there are several management tools that respond to the growing need for cost reduction and continuous improvement. The TPM, i.e, Total Productive Maintenance, is an approach to the management of equipment that seeks to maximize the overall efficiency, by reducing the losses associated with the production process, by involving all company employees. However, careless implementation of this philosophy has resulted in situations of failure and disrepute by employees. This paper aims to propose a methodology that runs counter this situation, leading the company through a sequence of steps to establish conditions for the successful implementation of TPM. The proposed methodology is validated by developing a pilot project dedicated to the packaging line of a cement factory and proved capable of creating the conditions for implementation of TPM in a consistent manner. The results predict a reduction in maintenance costs by transferring tasks to operators and increased productivity resulting from the decrease of stops. It is expected a real improvement in the OEE of 21% over the current level. More than tangible results, the biggest gain with the implementation of the proposed methodology will be cultural change triggered by the project.

Full textAbstract:
This research was concerned with investigating “the absence of Total Productive Maintenance (TPM)” at a plastic painting plant. TPM is a combination of operations and maintenance activities and is performed by operators under their own authority and is called “autonomous maintenances”. The author has tested the degree of implementation of TPM by using a sevenstep TPM implementation model this highlighted an absence of TPM in the organisation investigated. TPM is a relatively new concept in the South African automotive industry and has not been fully accepted by management as a solution to the maintenance problems in the organisation. Due to a long implementation period and the difficulty in measuring the benefits of the TPM program for the organisation TPM tends not to be implemented by companies. The research studies several maintenance philosophies each with its own advantages and disadvantages. The benefits that arise from the implementation of an effective TPM philosophy were explored. The development of an effective improved model for the implementation of TPM was investigated. Maintenance engineers and managers in any organisation can use this model to implement an effective TPM program. The seven-step TPM implementation model formed the basis for the compilation of a questionnaire. A survey was conducted to determine if an absence of TPM existed in a plastic painting plant. The results from the survey were drawn up and recommendations to further develop a model for the implementation of TPM was put forward.

Questo lavoro di tesi di laurea è stato realizzato in collaborazione con la Calzoni S.r.l di Calderara di Reno ed ha come obiettivo quello di mostrare come possa essere implementato un nuovo processo manutentivo in ottica TPM.
Nell'elaborato è stata inizialmente illustrata la teoria facente riferimento ad una gestione ideale della manutenzione, ovvero di una manutenzione che possa fare affidamento su un sistema informativo di supporto per la presa delle migliori decisioni riguardanti il sistema manutentivo e successivamente la sua applicazione al caso aziendale.
In particolare è stato mostrato come, all'interno di un'azienda come la Calzoni S.r.l, si è impostato il processo di raccolta dati e la loro organizzazione in un sistema informativo di manutenzione e come, nel frattempo, venga impostato un programma di manutenzione in ottica TPM.

La seguente tesi è stata sviluppata attraverso un percorso formativo di 6 mesi svolto presso l’azienda Berco S.p.a, Headquater del gruppo Berco Undercarriage nella sede dello stabilimento di Copparo (FE), un’azienda di grandi dimensioni, leader nel campo della produzione di componenti per carri cingolati.
Il progetto contenuto nell’elaborato ha lo scopo di aumentare la disponibilità, efficienza e tasso di qualità di una linea automatica di montaggio rulli.
La scelta di tale linea di assemblaggio, quale oggetto dell’attività, deriva dal fatto che fosse la linea più critica al mio arrivo in azienda, infatti presentava un valore iniziale di OEE (Overall Equipment Effectiveness) di 55%, che è un indicatore per stabilire l’efficienza di un impianto. Da tale valore possiamo vedere che l’impianto lavorava sfruttando solo la metà della sua capacità produttiva.
Analizzando la natura delle perdite della linea, tipicamente guasti, fermate maggiori di 10 minuti, e set-up si è deciso di introdurre i principi fondamentali del TPM (Total Productive Maintenance) attraverso l’introduzione della Manutenzione Autonoma oggetto della tesi e successivamente le tecniche di SMED (Single Minutes Exchange of Die).
Per la realizzazione di un’attività strutturata di Manutenzione Autonoma si è proceduto con l’analisi degli indici di efficienza della linea, in particolare valori di OEE e di disponibilità in modo da individuare le criticità tecniche delle macchine; successivamente sono stati identificati gli strumenti necessari a rendere operativa la manutenzione autonoma del reparto. Infine per addestrare e motivare il personale di linea direttamente coinvolto nel progetto sono stati realizzati dei corsi di formazione.
Al termine del lavoro è stata definita una procedura standard di implementazione della Manutenzione Autonoma già avviata nel reparto di Montaggio Rulli ed estendibile ai restanti reparti dello stabilimento.

O Brasil é o maior produtor mundial de cana-de-açúcar (Saccharum spp.), matéria-prima para produção de açúcar, etanol e bioeletricidade (a partir da biomassa). Nas usinas o sistema de colheita é o que mais onera os custos abrangendo a área agrícola. Cumpre assinalar que em virtude das exigências legais e ao menor custo do corte mecanizado em relação a outros sistemas de colheita, o setor tem investido em novas tecnologias e modelos de gestão dessa operação. O gerenciamento de todas as etapas da colheita (corte, carregamento e transporte) tem a finalidade de deixar o sistema mais eficiente e atender às necessidades de matéria-prima da unidade industrial. Com o propósito de atingir a excelência na produtividade e qualidade da colheita mecanizada, as usinas podem utilizar diversas metodologias e/ou programas de gerenciamento. A Manutenção Produtiva Total (MPT) apresenta-se como uma técnica gerencial, atuando na forma organizacional, no comportamento das pessoas, na forma com que tratam os problemas, não só de manutenção, mas de todos os trabalhadores diretamente ligados ao processo produtivo. Neste contexto o objetivo deste trabalho foi aplicar a metodologia MPT na operação de colheita mecanizada de uma usina de cana-de-açúcar, incluindo-se a avaliação dos indicadores de desempenho durante três safras: 2008/2009; 2009/2010 e 2010/2011. Os resultados obtidos confirmaram que essa metodologia é um modelo de gestão viável para a aplicação aqui proposta.Brazil is the largest sugarcane (Saccharum spp.) producer in the world. Sugarcane is the raw material for sugar, alcohol and bioelectricity (from biomass) production. In mills, the harvesting system is the heaviest issue in the budget including the agriculture area. It is worth mentioning that according to the legal demands and the lowest cost of mechanized cut in comparison with other methods, the area has invested in new technology and new management models for such operation. Management in all its stages (cutting, loading and transportation) has as main goal to make the system more efficient and fulfill the industrial unit raw-material needs. With the sole purpose to achieve excellence in production and quality of mechanized harvesting, mills can use different methods or management programs. Total Productive Maintenance (TPM) is introduced as a management technique, working in the organizational area, in peoples behavior, in the way they react, face and solve a problem, not just in maintenance, but with all workers directly involved in production process. In such context, the purpose of the following study was the use of the TPM in the harvesting operation in a sugar mill. Performance indicators during three crops are included: 2008/2009, 2009/2010 and 2010/2011. The obtained results confirmed that such method is a feasible management method for the proposed application of this study.

Rapporten handlar om att sätta upp en plan för implementering av ett mer strukturerat underhållsarbete på Valmet ABs gjuteri i Karlstad. Arbetet görs i kursen examensarbete för högskoleingenjörsexamen i maskinteknik på Karlstads universitet under våren 2014. Valmet har nyligen köpt upp gjuteriet på Lamberget i Karlstad. Där är det ett mycket eftersatt underhåll och finns i nuläget inte någon bra struktur på hur de arbetar med underhåll. Underhållsverksamheten är i behov av att systematiseras och integreras i Valmets övriga underhållsorganisation. Syftet med arbetet är således att utarbeta en plan för att strukturera underhållet på Valmets gjuteri i Karlstad. Arbetet är indelat i tre faser. - Nulägesanalys genom dels intervjuer av underhållspersonal samt kartläggning av utrustning - Skapa en målbild över hur man vill arbeta med underhåll, genom studiebesök hos andra liknande verksamheter, diskussioner med ledningen samt litteraturstudier. - Upprättande av plan för hur man ska ta sig dit. Vilka aktiviteter som skall utföras samt i vilken ordning, där bland annat lämpliga mätetal ska tas fram. Arbetet är baserat på metodiken TPM (total productive maintenance), det handlar dock inte om ett fullständigt införande av TPM utan begränsat till valda delar. Utifrån intervjuer med underhållspersonalen på gjuteriet samt observationsstudier och en kartläggning av maskinparken har en nulägesanalys gjorts. Denna nulägesanalys har visat de problem och utmaningar som finns på underhållsavdelningen på gjuteriet. En målbild över hur man vill arbeta med underhåll på gjuteriet har ritats upp utifrån de studiebesök samt intervjuer med personal i ledningen. Det mest vitala som framkommit i denna fas är hur viktigt ledningens engagemang är för att kunna genomföra ett förändringsarbete, samt hur viktigt det är med en bra kommunikation både mellan de olika avdelningarna, men också inom gruppen. Med hjälp av de två ovanstående faserna samt den teori som bearbetats under projektet har en plan upprättats för ett mer strukturerat underhållsarbete. Planen innefattar 12 punkter som behandlar de aktiviteter som bör implementeras, samt i den turordning de bör implementeras, för att få en bättre struktur på underhållsarbetet på Valmets gjuteri. De två enskilt viktigaste delarna i planen är enligt mig dels att anställa en person som ansvarar för den dagliga driften av underhållet. Samt att implementera underhållssystemet AM-underhåll, så att man kan få en bättre struktur på underhållsarbetet i form av arbetsordrar, mätetal och historik.The report is about setting up an Implementation plan for a structured maintenance work on Valmet ABs foundry in Karlstad. This work is the final part for the Degree of Bachelor of Science in mechanical engineering and takes place at Karlstad University in the spring of 2014. Valmet has recently bought the foundry at Lamberget in Karlstad. The maintenance work is much neglected and in the current state there is no good structure. The maintenance work is in need of systemization and integration into Valmets other maintenance organization. The purpose of the project is to develop a plan Implementation plan for a structured maintenance work on Valmet ABs foundry in Karlstad. The project is divided into three phases. - Situational analysis through both interviews of maintenance personnel and identifying the current equipment - Create a vision of how they want to work with maintenance through benchmarking against other similar businesses, and literature studies - Establishment of a plan for how to get there. What activities to be performed and in what order The work is based on the methodology TPM (total productive maintenance). However it is not about an implementation of TPM, but limited to certain parts. From interviews with the maintenance staff at the foundry, observational studies and an identification study of the machinery, a situational analysis has been made. This situation analysis has shown the problems and challenges that exist in the maintenance department at the foundry. A vision of how they want to work with maintenance on the foundry has been drawn, based on study visits and interviews with management staff. It is most vital that emerged in this phase is the importance of management commitment to implement a process of change. A good communication both between the different departments and within the group is also vital. Using the two phases above, together with the theory processed during the project, a plan has been established for a more structured maintenance. The plan includes 12 stages that addresses the activities that should be implemented, and in what order, in order to get a better structure on maintenance work at the foundry at Valmet. The two single most important elements of the plan are, in my mind, to hire a person who is responsible for the daily operations of the maintenance work. As well as to implement the maintenance system AM-underhåll, so you can get a better structure to the maintenance work in the form of work orders, metrics and history.

For many manufacturing companies, equipment is the largest capital investment andeffective maintenance of these assets can impact on profitability. It extends equipment life, improves equipment availability and retains equipment in proper condition. Conversely, poorly maintained equipment may lead to more frequent equipment failures, poor utilisation of equipment and delayed production schedules. Malfunctioning equipment may result in scrap or products of poor quality. Total productive maintenance (TPM) is one of the most popular concepts for improving process dependability (Nakajima 1988). It focuses on increasing the effectiveness of maintenance which is commonly measured by the overall equipment effectiveness (OEE). Ford Struandale Engine Plant (FSEP) applies lean manufacturing through its Ford Production System (FPS) which consists of twelve elements. One element of FPS is Ford Total Productive Maintenance (FTPM) with the objective to maximise the overall effectiveness of plant facilities, equipment, processes and tooling through the focused efforts of work groups and the elimination of the major losses associated with manufacturing equipment. The concern for FSEP management was that although FTPM is implemented, the OEE data revealed that equipment availability targets are not achieved. The researcher identified a gap to investigate the reasons for the poor performance. A literature study was conducted to search for relevant information on the subject. A questionnaire was constructed from the theoretical information and a survey was conducted. After data collection the results were captured and analysed. The researcher made conclusions based on the data and made recommendations. The main findings were that autonomous maintenance is not functioning well, spares management is not good and the Computerised Maintenance Management System is underutilised. The recommendations were that these issues must be addressed.

The Struandale Engine Plant (SEP) was set up in 1924 and was the 16th Ford plant outside North America. The plant has since produced a variety of different components ranging from wheel hubs, to engine components such as crank shafts and cylinder blocks, to the assembly of engines. Manufacturing at this plant has predominantly been via the job-shop method, where mass production techniques were used. The RoCam programme preparation started in 1999. In 2001, SEP experienced a very steep ramp-up due to an unexpected surge in volume requirements. This forced the plant’s Human Resources team to embark on an “emergency” recruitment drive to cover the required human resources to support the programme. Due to this action being taken by the Human Resources department, the educational level of the employees was at a very basic level and had an adverse effect on productivity. The SEP operating committee made a decision in 2004 to focus on the implementation and maintenance of the Ford Production System (FPS). This initiative was important because ageing equipment needed to be maintained at predetermined intervals through continuous improvement techniques that form part of the FPS programme. If these techniques are not in place, the Overall Equipment Efficiency (OEE) suffers. This programme comprises a number of critical elements such as FTPM that requires a certain education and skill level in effort to completely comprehend the system. Evidently, education was an issue and an effort had to be made to upgrade the workforce skill’s level, specifically the team leaders. On the 30th January 2008, Ford Motor Company of Southern Africa (FMCSA) had announced plans to invest more than R1.5-billion to expand its operations in South Africa for the production of Ford's next-generation compact pick-up truck iv and Puma diesel engine. In an effort to secure and retain the Puma contract at SEP, the plant had to prove that it could compete globally; hence it had to improve OEE levels to the world-class standard. The Puma engine contract had been contracted to South America, Turkey, Thailand, and South Africa. This was a strategic move in order to retain flexibility within the supply chain i.e. if one supplier / plant cannot deliver, demand can be shifted to one of three alternative suppliers. The problem statement which will be addressed by this research is: What are the main causes for the poor Overall Equipment Efficiency level (OEE) at the Struandale Engine Plant of Ford Motor Company of Southern Africa? The Primary Objective of this research is to: Identify the main causes for the poor Overall Equipment Efficiency level (OEE) at the Struandale Engine Plant of Ford Motor Company of Southern Africa

Lean manufacturing has seen its creators, Toyota, rise from insignificance in the middle of the previous century, to the biggest selling car manufacturer in the world today. Another Japanese car manufacturer, Honda, which has also been practising the principles of lean avidly during the last few decades, has also made huge strides towards becoming a dominant force in the car market. These Japanese companies‟ adoption of lean has seen many of their mass producing United States (US) and European counterparts struggle for survival. Maynard (2003:10) predicted that by the end of the decade, at least one of the „Big Three‟ auto makers in the US – Chrysler, Ford, and General Motors (GM) – would be forced to undertake significant restructuring to continue in operation. At the time of this writing all indications are that this prediction will come true. GM is in the process of major shareholding restructuring in an attempt to keep the company afloat, having run up insurmountable debts in the face of the current global economic downturn. Adopting the lean methodology has become a matter of necessity. The continued use of mass production methods alone is no longer viable; companies need to also employ lean methods intelligently in order to remain competitive. This study is regarded as a crucial endeavour to assist operations managers of manufacturing concerns in developing lean implementation strategies which will maximise the benefits to the organization.

The 737 program is currently producing 42 airplanes per month and will increase that production rate to 47 per month by 2017 and 52 per month in 2018 [1] [2]. In order to help meet these rates Boeing plans to increase the amount of automation in the shop that produces front and rear spars for all 737 variants. To mitigate risks associated with increased automation, the automation design team would like to implement an approach to equipment maintenance and operation known as Total Productive Maintenance (TPM). However the justification for TPM was not clear and an implementation strategy did not exist. The focus of this thesis therefore, is to clarify the justification for TPM, understand how TPM could impact the production system, identify the barriers and enablers of TPM implementation at Boeing, and present a TPM implementation plan that will be appropriate and effective for the particular context in which it will be executed. An analysis of current maintenance data and practices, case studies within the current factory, and a qualitative analysis of the future production system suggest that TPM could provide many quantitative and qualitative benefits and that the new production system is a good candidate for TPM. Results from a discrete event model show that TPM poses minimal risk of disrupting the future production system. Results of an employee survey show that the most important factors to successful TPM implementation are related to planning and building support prior to implementation. These findings influenced the design of the TPM implementation plan presented in this thesis, which focuses initially on building support, planning, and training. As the airline industry adopts automated equipment in response to increased competition, TPM may become an important strategy for staying competitive. The multi-pronged analyses demonstrated in this thesis for justifying TPM, the survey method used to understand the company-specific barriers and enablers of TPM, and the method of designing a customized TPM implementation plan based on the insights from these analyses can serve as a general model for implementing TPM within Boeing and within the broader airline industry.

Full textAbstract:
For a tyre manufacturing company to compete nationally and internationally, the maximum utilization of their equipment is extremely important. Thus, having a maintenance system in place that will ensure this will be essential. In today’s competitive environment, the need to go further than just scheduling maintenance in accordance with manufacturer’s recommendations as a method of improving productivity and product quality was quickly recognized by those companies who were committed to total quality management programmes. The objective of this study was to propose an appropriate strategy for the implementation of Total Productive Maintenance at Continental Tyre South Africa. To achieve this, the current Total Productive Maintenance (TPM) programme, in the steel stock preparation division in affiliated Continental plants in Otrokovice in the Czech Republic and Puchov in the Slovak Republic was evaluated. A comprehensive literature study was performed on Total Productive Maintenance programmes. A questionnaire was designed based on the guidelines in the literature study in order to establish the effectiveness of implemented TPM programmes. The researcher used the random sampling method of selection and distributed the questionnaire to 62 potential respondents via hand-outs from each plant’s respective heads of departments. 56 completed questionnaires were returned and these were processed and analyzed using Microsoft Office Excel 2003, running on the Windows XP suite of computer packages. The opinions of the various respondents were compared with the guidelines provided in the literature survey, in order to identify how to answer two main questions the author wanted to use as part of selecting an appropriate implementation approach for TPM at Continental Tyre South Africa. These were: • How much are the employees involved and empowered to perform their TPM tasks?; and • How effective is the implemented TPM programme? The following were the main recommendations and conclusions: • The experiences gained by plants like Otrokovice and Puchov must be used as a guideline for introduction and implementation; • The employees that will be required to perform the TPM tasks must be properly trained and they should receive the necessary tools to perform their tasks; • It is essential that everyone throughout the entire manufacturing organization is involved from the start in the development, improvement and maintenance of the TPM programme and that the driving force behind it should be a combination of maintenance, production and quality; and • TPM will achieve it’s objectives if: • The equipment effectiveness can be improved; • Autonomous maintenance is achieved; • Planned maintenance is in place; • Staff are trained in relevant maintenance skills; and • Early equipment management can be achieved.

Full textAbstract:
Effective and efficient operations management is the cornerstone of any company's success. Presently, because of cost-cutting pressures, all investors look out for companies' operations before making any investment commitment. The South African Government (through the Department of Public Enterprises), as an owner and investor in Eskom, is looking at optimising operational excellence within state-owned enterprises like Eskom.
Eskom is presently experiencing problems with increased electricity consumption which it cannot meet due to the limited plant capacity it presently has. These challenges are forcing Eskom to be more efficient and effective in management of the present plant assets (like Matimba Power Station) it presently operates. Matimba Power Station has consistently shown improvement in the areas of plant, financial and operations performance over the last three years. It is presently the standard bearer for the whole Eskom in terms of plant and operational performance. Asset management (through maintenance and management thereof), especially preventative management with in a power utility like Eskom, is a critical factor because supply (generation of electricity) has to meet demand (consumption of electricity) instantaneously as electricity cannot be saved. The planning, scheduling and execution of maintenance (through a work management process) to ensure success of business operations are very critical. An Eskom document titled Routine Work Management
Manual emphasised the criticality of preventative management and included a six-step process of work management within the power generation business. The Japanese success in ensuring that operations costs are limited by implementing total productive maintenance (which includes work management) is suggested in the study as a way to go for operational success at Matimba Power Station. Many of the research studies done at Eskom in regard to maintenance were based on and confined to a sampling population of senior staff members like managers, engineers and supervisors. Experience has shown that progress of implementing change (whether in systems or structures) is slow if there was no proactive involvement of all participants and stakeholders, especially employees at lower levels involved in operations. A work management process, which is one of the pillars of total productive maintenance, was recently implemented at Matimba and is currently experiencing teething problems which are being attended to. Employee involvement in making sure of the success of work management is critical. The study investigates the implementation of work management from the employees' perspective in order to address problems for possible full implementation of total productive maintenance.Thesis (M.B.A.)--North-West University, Vaal Triangle Campus, 2010.

Full textAbstract:
The international competition and the demand to increase productivity of manufacturing and production lines have attracted the management of industrial organisations from a wide spectrum to implement Total Productive Maintenance (TPM) as a tool for improving productivity and system’s output. Some Libyan companies are still facing many problems concerning maintenance activities of assets. Inadequate maintenance can have cost impact on the maintenance performance and production. Following the privatisation of the Cement industry in Libya, companies are now interested in improving productivity, reducing cost, improving maintenance procedures and reducing the negative effect on the environment. To address the above issues within the Libyan industry, this research presents an investigation into the need for implementation of Total Productive Maintenance (TPM) in Libyan cement industry. TPM is a generic maintenance philosophy that transforms maintenance activities from what is considered to be the 'necessary evil' into an essential part of the business. In TPM, maintenance and downtime is integrated within the production system and scheduled as an essential part of the manufacturing process. This thesis investigates the problems facing four cement factories in Libya. Following a comprehensive literature review around the research problem; case studies, statistical data, semi-structured interviews, detailed questionnaires and site visits are utilised to evaluate and understand the problems within the four factories. Based on the analysis, this thesis suggests a new Framework and associated models for implementing Total Productive Maintenance (TPM) and identifying the key Factors to improve the overall maintenance performance.

This treatise investigates the underlying factors that are hindering the improvement of Overall Equipment Effectiveness at the Ford Struandale Engine Plant. In January of 2008 the Ford Motor Company announced plans to invest more than R1.5 billion to expand operations for the production of Ford's next-generation compact pickup truck and the PUMA diesel engine. Ford will use the investment to expand operations both in Silverton for the production of 75 000 units of a new bakkie and in Port Elizabeth for 220 000 units of its new-generation PUMA diesel engines (http://www.autoblog.com /2008/01/31/ford-to-invest-209m-in-south-africa-for-new-ranger-pickup/). Only five Ford plants globally will be producing the PUMA engine (Turkey, UK, Thailand, Argentina and South Africa – Ford Struandale Engine Plant). The Ford Struandale Engine Plant will be the only plant which will have the I4 assembly, I5 assembly and 3C (Crank, Cylinder Block, and Cylinder Head) machining and the expectations of operating in a lean environment is high. The management team at the Ford Struandale Engine Plant needs to understand what the underlying factors that are hindering the improvement of Overall Equipment Effectiveness of the plant or, in other words, they need to be informed of the total benefits of TPM. A literature review was conducted to determine what the theory reveals about Overall Equipment Effectiveness, the three factors of OEE (Availability, Performance Efficiency, and Quality), the influence of Six Big Losses on each of the factors and the role of Total Productive Maintenance in improving OEE by eliminating these Six Big Losses. A Ford literature study was conducted to reveal the current literature being applied at Ford. This was then followed by an empirical survey conducted within the Ford Struandale Engine Plant. In addition, a task team formed to analyse the current maintenance operating strategy. Finally, the findings from discussions with the task team, the empirical survey, Ford Struandale Engine Plant literature survey and a general literature survey were amalgamated to draw conclusions relating to the Ford Struandale Engine Plant. These conclusions indicate what the underlying factors are that are hindering the improvement of Overall Equipment Effectiveness of the Ford Struandale Engine Plant facilities and equipment. Then recommendations are made as to how the Ford Struandale Engine Plant can improve the Overall Equipment Effectiveness of its facilities and equipment.

Today's successful manufacturing organisations require a significant competitive advantage, hence the need to implement and develop a Total Productive Maintenance (TPM) strategy. This research paper addresses the impact of TPM on manufacturing performance at the Colt production facility (DCSA). A literature survey was undertaken into the elements and benefits of TPM. Questionaires were also sent to all levels of people at the Colt production facility for their views on TPM and the impact, they believe, it has had on manufacturing performance. In conclusion, this research paper has also led to the development of recommendations to improve TPM activities at the Colt production facility. From the research, it was shown that top management support for TPM activities is needed and that training is an essential factor for TPM's success in improving manufacturing performance.

[EN] This thesis explores the difficulty in implementing TPM (Total Productive Maintenance) and through the analysis of the existing literature:
- Define a proposal to establish which is the most suitable TPM implementation model and the key development objectives that should be reached in each step.
- Define an exhaustive list of facilitators and barriers that influences the TPM, defining hierarchical links that govern them and their similarities with the facilitators for continuous innovation.
- Define the relationships between the facilitators and the steps of the proposed model, through the assessment of the impact on their development objectives and the existing hierarchical links between facilitators.
In addition, it pinpoints that the difficulty of implementing TPM can be reduced by the use of two suggested questionnaires. The first is approaching the TPM implementation model and the second is more focused on the TPM facilitators. Both intend to cover the lacks in the existing development models and methodologies and be a complement to guide the personnel in charge of the TPM implementation.
Through a longitudinal analysis, this thesis validates that the suggested questionnaires are suitable for their application in a company, demonstrating how the improvement of the items described in these questionnaires or proposed guidelines are linked with an improvement in the TPM implementation results. It concludes that the use of these questionnaires does not interfere or harm the development of the implementation methodologies, but reinforce them by focusing on the vision and the implementation efforts, supporting the relevant aspects to perform in the right way. It also addresses the fact that the enhancement of facilitators due to their hierarchical links improves the sustainability and reduces the need of periodic revivals of the whole TPM implementation process.[ES] La presente tesis doctoral profundiza en la dificultad que supone la implantación del TPM (Total Productive Maintenance) y a través del análisis de las publicaciones existentes: - Elabora una propuesta que concreta cual es el modelo de implantación del TPM más adecuado y los objetivos de desarrollo fundamentales que se deberán de conseguir en cada paso. - Define una relación exhaustiva de facilitadores y barreras que influyen sobre el TPM, definiéndose las relaciones jerárquicas que los regulan y sus semejanzas con los facilitadores propios de la innovación continua. - Define las relaciones entre los conjuntos de facilitadores y los pasos de modelo propuesto, a través de la valoración del impacto que pueden tener sobre sus objetivos de desarrollo y la relación de jerarquías existente entre los facilitadores. Así mismo, concreta que la dificultad que presenta la implantación del TPM, puede reducirse mediante el uso de dos cuestionarios propuestos, uno de aproximación al modelo de implantación del TPM y otro de aproximación a los facilitadores del TPM, que ayuden a suplir las carencias de los modelos y metodologías de desarrollo existentes y sirvan como complemento que oriente al personal de planta, encargado de implantar el TPM, en el buen camino. A través de un análisis longitudinal, en la presente tesis doctoral se valida que los cuestionarios elaborados son adecuados y pueden ser utilizados en una empresa real, mostrando como una mejora de los ítems descritos en estos cuestionarios o guías propuestos, va relacionada con una mejora en los resultados de la implantación del TPM; concluyéndose que el uso de estos cuestionarios en ningún momento perjudica o interfiere en el desarrollo de las metodologías de aplicación, sino que las refuerza, sirviendo de ayuda para centrar la visión y el esfuerzo de la implantación, ayudando a reforzar aspectos relevantes que dirijan su desarrollo por el buen camino. También se muestra como la potenciación de los facilitadores, y debido a su relación de jerarquías, ayuda al sostenimiento de los resultados en el tiempo, así como a reducir la necesidad de revitalizaciones periódicas del proceso de implantación del TPM.
[CAT] La present tesi doctoral aprofundeix en la dificultat que suposa l' implantació del TPM (Total Productive Maintenance), tot això per l'anàlisi de les publicacions existents: - Elabora una proposta que concreta quin és el model d'implantació del TPM més adequat i els objectius fonamentals de desenvolupament en cadascú dels passos. - Defineix una relació exhaustiva de facilitats i barreres que influeixen sobre el TPM, definint les relacions jeràrquiques que els regulen i les seves semblances amb els facilitadors propis de l' innovació contínua. - Defineix les relacions entre els conjunts facilitadors i el passos de model proposat, a través de la valoració de l'impacte que pot tindre al voltant dels seus objectius de desenvolupament i la relació amb les jerarquies existents entre tots els facilitadors. Així mateix, concreta que la dificultat que presenta d'implantació del TPM, pot reduir-se mitjançant l'ús de dos qüestionaris proposats, un d'aproximació al model d'implantació del TPM i un altre d'aproximació als facilitadors del TPM, que ajuden a suplir les carències dels models i metodologies de desenvolupament existents i serveixen com a complements que orienten al personal de planta, encarregat d'implantar el TPM, pel bon camí. Per un anàlisi longitudinal, en la present tesi doctoral es valida que els qüestionaris elaborats són els adequats i poden ser utilitzats en una empresa real, mostrant com una millora dels ítems descrits en aquestos qüestionaris o guies proposades; va relacionada amb una millora dels resultats de l' implantació del TPM; concloent que l'ús d'aquests qüestionaris en ningú moment perjudica o interfereix en el desenvolupament de les metodologies d'aplicació, sinó que les forces, serveixen d'ajuda per centrar la visió i l'esforç de l' implantació, ajudant a reforçar aspectes importants i rellevants que dirigeixen el seu desenvolupament pel bon camí. També és mostra com la potència dels facilitadors, i degut a la seva relació de jerarquies, ajuda al sosteniment dels resultats en el temps, així com a reduir la necessitat de revitalitzacions periòdiques del procés d'implantació del TPM.

Full textAbstract:
Purpose: this thesis study aims to provide an analysis and an assessment of the current operations’ performance effectiveness at Nobel Biocare’s production plant in Karlskoga, Sweden and to describe the potential for improvement. It intends to clarify the importance of performance measurement and explain Overall Equipment Effectiveness (OEE) metrics in particular.Furthermore, it strives to identify causes for inefficiency in production and suggest recommendations to minimize losses.
Methodology: the study is using both qualitative and quantitative approaches in parallel as measurements are implemented to discover effectiveness rates and detect causes for production losses while assessments are made using different models, such as the Capability Maturity Model(CMM) and OEE assessments, in order to evaluate the current development level and the potential for improvement.
Findings: the research finds that major losses are closely related to frequency of changeovers in machining processes, where average effectiveness rates were 68%. In surface treatment and packaging equipment inspected, the values were found to be between 46% and 59% as the major common cause was the absence of work due to unstable flow of orders. Assessing process orientation and maturity levels, the findings indicate on high levels in general. However, areas of weakness were identified in the different processes in which the potential for improvement is embedded. In those areas, lower OEE values were registered; low levels of maturity and process orientation were found, as low development of losses improvement were assessed. The study finally suggests that the areas of weakness suffer from lack of learning orientation that is ought to be improved and at the same time, a variety of specific recommendations are provided.

O aumento da competitividade no mercado tem estimulado uma grande busca por conceitos e técnicas que auxiliem os processos de melhoria do desempenho de sistemas produtivos, sobretudo no que tange a produtividade e qualidade. Neste contexto, o estudo da experiência das indústrias japonesas revela que a sua competitividade foi conquistada e tem sido sustentada com base em modelos integrados voltados ao planejamento, implementação e condução dos chamados programas de melhoria da produtividade e qualidade (PMPQ\'s). Tais modelos são baseados em filosofias especificas de gestão da manufatura, sendo que os três seguintes, despontam com grande destaque e constituem o objeto central de estudo desta dissertação: 1. Manufatura Just-in-Time (JIT); 2. Total Quality Control (TQC); 3. Total Productive Maintenance (TPM). O presente trabalho é dedicado ao estudo conceitual destes modelos. Para isso foi elaborado um quadro conceitual sobre a estrutura geral de um PMPQ. Tomando-se este quadro como pano de fundo, estes três modelos foram então caracterizados, analisados e avaliados de forma comparativa. Esta análise possibilitou a identificação dos aspectos específicos a cada um, más também evidenciou muitas semelhanças (exemplo: sua aplicação como instrumento de gestão estratégica da manufatura) entre os mesmos.Along the last decades a series of geopolitical and macroeconomic changes have made the competition in international trade tougher. Although the brazilian economy has not been so integrated to the international market, effects of such trend are already disturbing the dynamics of Braazilian companies. Therefore an increasing number of companies have driven themselves into processes aimed to increase competitive power through strategies that value mainly attributes like cost and quality. Such processes have in general a broad scope and are usully called Productivity and Quality Improvement Programs (PQIP\'s). In this context, new paradigms for planning, implementation and guidance of such programs have risen from japanese industries. Among these paradigms, three of them are worthy of special attention and represent the main object of this work. Each of these paradigms have their own manufacturing management philosophy and are the following; 1. the paradigm based on Just-In-Time (JIT) Manufacturing philosophy, 2. the paradigm based on Total Quality Control (TQC) philosophy and 3. the paradigm based on Total Productive Maintenance (TPM) philosophy, This work is dedicated to the conceptual investigation of these paradigms. First, a conceptual framework for the general structure of a PQIP was built. Then it was taken as a frame in order to present, analyse and evaluate comparatively the three paradigms. The investigation resulted in the recognition of features that are unique to each one but it also exposed many similarities among them. One commom feature is that all three admit their use as a tool for strategic management of manufacturing, an activity that has been overlooked by western industrial companies organized and managed in traditional way. The investigation also revealed a clear resolution of these paradigms to search the achievement of economic objectives of a firm without confronting and neglecting the social and humanistic demands expressed by the human resources engaged in production.

Nell'elaborato viene trattato il processo di implementazione di tecniche di Total Productive Maintenance (TPM) su di un impianto pilota all'interno dell'azienda Bonfiglioli Riduttori S.p.A. Dall'analisi dei dati dello storico degli interventi a guasto, effettuati sull'impianto, si sono ottenuti i parametri manutentivi di interesse per avere un quadro generale della situazione di partenza e sono state identificate due tipologie di manutenzione, come previsto dal TPM: l'automanutenzione affidata agli operatori e una serie di interventi programmati di preventiva a carico dell'ente manutenzione. Sono stati effettuati anche una serie di interventi migliorativi per incrementare l'efficienza dell'impianto. In conclusione sono stati confrontati i parametri di partenza con quelli di fine progetto per valutare i miglioramenti conseguiti valutando anche l'aspetto economico degli investimenti fatti. Dai dati ottenuti alla fine del percorso, sono state fatte le dovute considerazioni e sono stati proposti degli elementi di riflessione.

Mestrado em Ciências EmpresariaisÉ hoje reconhecido que a principal via para reduzir custos de operação passa necessariamente pela eliminação de desperdício e perdas nos diversos processos da cadeia de valor. A necessidade de obter ganhos de eficiência através da eliminação de desperdício, obriga as empresas a assumir a questão da melhoria contínua como um tema central na aquisição de vantagens competitivas que lhes permitam ocupar uma posição ganhadora no mercado. A integração da filosofia Lean nas diversas áreas de conhecimento das organizações, originou uma nova abordagem da gestão de Manutenção, denominada por Lean Maintenance. Esta metodologia segue a base do Total Productive Maintenance, ganhando particular destaque nas empresas cuja atividade depende fortemente dos seus ativos físicos. O alinhamento dos objetivos das empresas com a sua missão, visão e valores só é possível através do desenvolvimento de metodologias que permitam o desdobramento estratégico nas diversas perspetivas de valor da organização. Face à relevância do tema, este estudo apresenta uma revisão de literatura sobre a evolução histórica da gestão de manutenção, descrevendo o modo como evoluiu para uma área de conhecimento complexa e preponderante para uma gestão de ativos físicos eficiente e de elevado valor. Posteriormente é apresentado um estudo de caso demonstrativo dos benefícios que a implementação de uma metodologia Lean Maintenance pode trazer a uma empresa do sector dos transportes.
It´s a fact in our days that the way to decrease operational costs must achieve waste~reduction in value chain flow. The need to obtain efficiency gains through the elimination of waste leads companies to take the continuous improvement as main issue to achieve competitive advantage in the market. The integration of Lean philosophy in all company’s subject, created a new vision in maintenance management, called Lean Maintenance. This methodology is driven by Total Productive Maintenance, winning highlights in companies who activities depend a lot from physical assets. The alignment of objectives with its mission, vision and values is only possible by the development of methodologies that allow the strategic deployment in all the perspectives of value. Regarding the relevance of the theme, this study show’s a literature review about the history and development of Maintenance, describing the way how a complex knowledge can be so important to reach an efficient and high value physical asset management. Posteriorly is presented a case study to demonstrate the benefits that the implementation of a Lean Maintenance methodology can bring to a road transport company.

Detta examensarbete är utfört på Astrazeneca Södertälje inom Meto-försteg som är en del av fabriken API, med syftet att effektivisera underhållsarbetet. En kartläggning av det förebyggande underhållet genomfördes, i syfte att identifiera underhållsarbete som utförs dubbelt av både operatörer inom API och underhållsleverantören Caverion. Examensarbetet presenterar en redogörelse för begrepp inom underhåll, TPM (Total Productive Maintenance) och beslutsmodellen QFD (Quality Function Deployment) vilka utgör den teoretiska utgångspunkten för resultat och analys. Examensarbetet bygger på insamlade observationer och intervjumaterial från personal verksamma inom drift och underhåll. Studiens resultat visar att det genomförs överlappningar i underhållsarbetet, exempelvis inom veckotillsyn och förebyggande underhåll (FU) inom fabriksdelen Meto- försteg. Både operatörer och Caverion genomför underhållsåtgärder som innefattar visuell kontroll av oljenivåer, läckage, missljud, vibrationer för ett antal maskiner. En tydligare fördelning av underhållsåtgärder mellan operatörer och Caverion kommer bidra till effektiviseringen av underhållsarbetet.This thesis was carried out at Astrazeneca Södertälje within Meto-pre stage, which is part of the factory API, intending to streamline the maintenance work. Apreventive maintenance survey was carried out, to identify maintenance work that was performed twice by both API operators and the maintenance provider Caverion. The thesis presents an account of concepts in maintenance, TPM (Total Productive Maintenance), and the decision model QFD (Quality Function Deployment) which constitute the theoretical starting point for results and analysis. The thesis is based on collected observations and interview materials from staff active in operations and maintenance. The results of the study show that there are overlaps in maintenance work, for example in weekly supervision/inspections and preventive maintenance (FU) within the factory part Meto-pre stage. Both operators and Caverion carry out maintenance operations that include a visual control of oil levels, leakage, noise, vibrations for several machines. A clearer distribution of maintenance measures between operators and Caverion will contribute to the streamlining of maintenance work.

El sector textil y confecciones es uno de los sectores con mayores expectativas de crecimiento sostenible de la industria y uno de los que mayor competencia acumula con otros países del sector internacional. Este sector abarca diferentes tipos de procesos, que van desde tratamiento de fibras, hilatura, tejido y confección. El presente análisis recae sobre la baja disponibilidad que presenta los equipos en el proceso de teñido. Este proceso se mide a partir de los reprocesos que existen debido a que se ejecuta mantenimientos correctivos, el cual afecta la producción en el teñido de telas. Asimismo, se logra evaluar el tiempo promedio entre fallas (MTBF) y el tiempo promedio de reparación (MTTR), lo que indica la variabilidad por debajo del objetivo esperado por la organización.
Por otro lado, en el tercer capítulo se desarrolla le propuesta de mejora a partir del desarrollo del estado del arte del primer capítulo. Para ello se propone la metodología da seguir de acuerdo con una combinación de RCM y TPM. Bajo esta metodología se desarrolla diferentes actividades y estrategias que permitirán detectar equipos críticos e implementar planes de mantenimiento preventivo mecánico y eléctrico. Además, se incluye como parte de este sistema la implementación de un mantenimiento basado en condición (predictivo) y autónomo. Finalmente, el tercer capítulo finaliza con el soporte de la metodología 5 ‘’S’’ y la evaluación económica a partir de la estructura de costos que tiene prevista el proyecto.
Finalmente, en el capítulo cuatro se presenta la validación de la propuesta de mejora a partir de la validación de los resultados en el software Arena. Ello permite concluir que los indicadores MTTR y MTBF ha logrado alcanzar los objetivos presentados en la propuesta.The textile and garment sector is one of the sectors with the highest expectations of sustainable growth in the industry and one of the sectors with the highest competition with other countries in the international sector. This sector covers different types of processes, ranging from fiber treatment, spinning, weaving and confection. The present analysis falls on the low availability that presents the equipment in the process of dyeing. This process is measured from the reprocesses that exist due to the execution of corrective maintenance, which affects the production of fabric dyeing. Likewise, it is possible to evaluate the average time between failures (MTBF) and the average repair time (MTTR), which indicates the variability below the target expected by the organization. On the other hand, in the third chapter the improvement proposal is developed from the development of the state of art of the first chapter. For this, the methodology to be followed is proposed according to a combination of RCM and TPM. Under this methodology, different activities and strategies are developed to detect critical equipment and implement mechanical and electrical preventive maintenance plans. In addition, the implementation of a maintenance based on (predictive) and autonomous condition is included as part of this system. Finally, the third chapter ends with the support of the 5 '' S '' methodology and the economic evaluation based on the cost structure planned by the project. Finally, chapter four presents the validation of the improvement proposal based on the validation of the results in the Arena software. This allows concluding that the MTTR and MTBF indicators have achieved the objectives presented in the proposal.

La Lean Production è un tema di estrema attualità per tutte le aziende che abbiano compreso l’importanza di produrre di più, con le risorse che si hanno a disposizione, eliminando sistematicamente tutte le attività che non creano valore aggiunto.
La Produzione Snella è diventato un metodo per incrementare la competitività, riducendo l’incertezza e aumentando il servizio fornito al cliente.
Nella realtà attuale vi è ancora una scarsa diffusione dei concetti Lean. Le cause di questo problema sono imputabili soprattutto alla cultura del management aziendale, alla mancanza di efficaci strumenti tecnologici a supporto, e in alcuni casi, la scarsa disponibilità delle imprese ad abbracciare la filosofica “snella”.

The purpose of this thesis is to implement Total Productive Maintenance (TPM) in Nigeria Plastics Manufacturing Company. Manufacturing companies round the world pay huge amount of money for purchasing new equipments to boost their production however nothing or little is done to achieve or obtain full output from the machine for which it is intended to do. Small losses in time or deviations from planned or calculated capability are taken as usual machine performance. But currently as a result of improved capability levels and demand of quality product at lower prices, purchasing latest machine/equipment is not a way out unless it is completely used. Total Productive Maintenance (TPM) is a method that involve everybody totally, from high management to all workers to implement a complete maintenance program for all machine/equipment during its life. This method ends up in most effectiveness of tools, equipment, virtuously improved workers, tidy up working area, neat and clean working environment. A structure is going to be developed with the potential of evaluating the impact of implementing total productive maintenance within. By evaluating the result or outcome of Total Productive Maintenance (TPM), manufacturing companies can create sensible/smart decisions to improve the potency and standard of the machine, equipment and also the product on XYZ Plastics Manufacturing Company in Nigerian.

Detta examensarbete beskriver hur förarbetet till att datorisera ett underhållssystem genomförs. Uppdragsgivare är Lear Corporation i Torslanda. Examensarbetet består av två delar: utvärdera en på förhand vald programvara och att dokumentera allt förebyggande underhåll (FU). Syftet är att få bättre kontroll och planering av förebyggande underhåll (FU) i framtiden. Programvaran som skall utvärderas om den är lämplig för ändamålet heter Tekla™ Maintenance.
Målet var att dokumentera allt förebyggande underhåll (FU) för två av tre liner i Lear Corporations fabrik i Torslanda.
Det visade sig att Tekla™ Maintenance uppfyllde de krav som fanns. De krav som fanns var bland annat när det var dags att göra ett förebyggande underhållsarbete ska programmet automatiskt tala om att nu skall det utföras. Ett användarvänligt gränssnitt var också efterfrågat. Rapporten innerhåller även en beskrivning av hur Tekla™ Maintenance är uppbyggt.
För att få en bild av hur det är att arbeta med programmet i verkligheten genomfördes en benchmarking mot Plastal AB. Plastal AB hade mycket goda erfarenheter av att arbeta med programmet och kunde därför varmt rekommendera det.
All dokumentation av förebyggande underhåll sker i dag på papper. Eftersom denna dokumentation inte innehöll tillräckligt med information skedde nedbrytningen från grunden. Varje line delades in i mindre områden så som line, kringutrustning och moment- och skruvdragare. När allt var dokumenterat fick underhållspersonalen tala om vad för slags förebyggande underhåll som skulle göras på all utrustning. Allt skrevs in i en Excel-fil som skall användas för att importera informationen till Tekla™ Maintenance i framtiden. Filen innerhåller över 2000 stycken objekt, vilket ger en bra grund för underhållsarbetet i framtiden.
This Bachelor Thesis deals with how to prepare a computerization of a Maintenance Management System. The Bachelor Thesis is written by commission at Lear Corporation in Torslanda, Sweden. The paper is divided into two parts: evaluate a software and document all preventive maintenance. The purpose is to get better control and planning of preventive maintenance in the future. Tekla™ Maintenance is the software that is going to be evaluated.
The aim is to document all preventive maintenance for two of three production lines at Lear Corporations factory at Torslanda, Sweden.
The research shows that Tekla™ Maintenance met the specifications. One of the basic requirements was to automate the management of prevention maintenance activity, by issuing work order. Furthermore a user friendly interface was required. A description of Tekla™ Maintenance is included in the report.
To get a feeling of how the programme perform in real world, benchmarking was preformed against Plastal AB. The benchmarking resulted in that Plastal AB recommended the Tekla™ Maintenance programme.
Currently the documentation does not contain enough detailed information to allow a thorough review of all production lines.
By dividing all lines into zones, all activities at each zone have been documented.
Feedback form the operators was given, about what type of preventive maintenance that is required.
To be able to put all the information into Tekla™ Maintenance, an Excel file has been made. This file contains over 2000 entries and should provide a solid base for future preventive maintenance.

Full textAbstract:
Por estar diretamente sujeita a fatores econômicos de nível global, a mineração tende a se desenvolver para buscar processos produtivos mais enxutos, aliando menores custos operacionais a melhores taxas produtivas. Neste contexto, o objetivo principal deste trabalho é avaliar o comportamento geral da curva de tempo em manutenção preventiva de uma frota de caminhões em uma mineração de grande porte, sendo a análise realizada em uma janela temporal baseada em um período econômico de mínimo local nos preços do cobre. A partir do comportamento observado é feita uma discussão sob as premissas da metodologia de gestão nomeada Manutenção Produtiva Total de forma a se debater os possíveis principais riscos e/ou consequências que podem ser enfrentadas pelo projeto e como estas decisões qualitativamente indicam o grau de maturidade na integração operacional entre produção e manutenção em um projeto minerário. Ao final, pode-se concluir que ainda é necessário um intenso trabalho em se traduzir as premissas da MPT para a indústria mineral, buscando-se adaptar processos e métricas que sejam mais condizentes ao ambiente da indústria extrativa (que é muito diferente da indústria de manufatura, onde o programa teve início). Além disso, fica claro que a aplicação da MPT é possível e bem-vinda na mineração já havendo de vários estudos acadêmicos na área - ou seja, o ponto em questão mais desafiador provavelmente é que seja desenvolvido um programa de MPT de forma endógena em um projeto mineral.As it is directly under global economic factors, the mining industry tends to develop to seek leaner production processes, combining lower operational costs to better productive rates. In this context, the main objective of this study is to evaluate the general behavior of the time spend in preventive maintenance of a truck fleet from a large-scale mining project, being the analysis performed in a time window based on an economic period of local minimum in copper prices. From the observed behavior a discussion is made under the assumptions of the management methodology named Total Productive Maintenance in order to discuss the possible main risks and/or consequences that can be faced by the project and how these decisions qualitatively indicate the degree of maturity between production and maintenance in a mining project. In the end, it can be concluded that an intense work is still needed to translate the TPM premises into the mineral industry, being necessary to seek ways to adapt processes and metrics that are more suited to the extractive industry environment (which is very different from the manufacturing industry, where the program started). In addition, it is clear that the application of TPM is possible and welcome in mining since there are several academic studies in the area - in other words, the most challenging point in question is probably that an endogenous TPM program is developed within a mineral project.

L'industrie de la production actuelle est caractérisée par des progrès significatifs : une augmentation massive de la haute technologie, l'émergence de clients exigeants, des marchés compétitifs, une qualité de produit variée et des demandes aléatoires ont exigé la collaboration des aspects interdépendants de la production. La production, la maintenance et la qualité sont les aspects les plus critiques du système industriel. Nous nous intéressons à l'optimisation de la maintenance qui joue un rôle essentiel dans la satisfaction du client, la durabilité et le développement des entreprises. Notre étude est centrée sur le développement de la production et de la maintenance intégrées dans une carte de contrôle de la politique de qualité. Nous proposons de nouvelles stratégies de maintenance intégrée avec une analyse approfondie des améliorations continues de la fiabilité du processus de production et traitées sous les contraintes des exigences du client (Service, qualité et coût). L'intégration et la coordination optimale de ces facteurs de production n'est pas facile et représente un défi pour les entreprises industrielles, et sont plus difficiles avec les causes multi-assignables de la variation du processus de production. Pour répondre à ce problème, ce travail de recherche a utilisé l'outil carte de contrôle en combinaison avec les principes de l'AFNOR connus sous le nom de Règle des sept comme impliqués dans la gestion de la qualité. Pour surveiller, analyser et diriger les actions de maintenance appropriées pour l'amélioration continue de la fiabilité du système le long des différents scénarios de processus multiples comme niveaux de décision. Nous utilisons les interactions entre le processus de production et la qualité du produit pour des stratégies de maintenance qui réduisent la défaillance du système de production en améliorant la fiabilité du processus et en réduisant les produits non conformes. L'étude a porté de manière significative sur la qualité, les outils de qualité et leurs applications dans le contrôle de la production et de la maintenance. La technique que nous avons utilisée pour optimiser la maintenance et le contrôle de la qualité d'un système de production intégré est un outil de carte de contrôle basé sur la mesure et l'analyse statistique des paramètres de qualité. Nous modélisons différents problèmes de production et développons une politique de contrôle pour des systèmes de production à défaillance aléatoire qui doivent satisfaire les exigences des clients de manière dynamique tout au long de l'horizon de production fini. Nous avons introduit un modèle mathématique pour minimiser les coûts totaux de production, d'inventaire, de maintenance et de contrôle de la qualité. L'optimisation de la stratégie de maintenance a été intégrée dans un outil d'information sur les cartes de contrôle. Sur la base de la variation du taux de production et de son impact sur la dégradation de la machine, le nombre de maintenance, les temps et les intervalles nécessaires à une prise de décision prudente sont déterminés par l'algorithme développé. Dans ce contexte, cette recherche présente la dérivation pour différents cas de toutes les probabilités pour le processus d'être dans ou hors de contrôle, les durées moyennes d'exécution, et les durées de cycle de restauration. Sur la base du facteur de dégradation, de nouvelles équations de taux de défaillance sont formulées, puis le taux de défaillance moyen pour chaque cas, nous avons formulé différents modèles d'optimisation des coûts de maintenance. L'approche proposée est utile pour le calcul précis et la minimisation du coût total de maintenance. Elle optimise le coût total de production en considérant tous les états possibles du processus de production dus à des causes multiples. Notre travail contribue à l'émergence de techniques de gestion de la qualité et d'amélioration des performances qui contribueront au développement des entreprises de productionThe current production industry is characterise by significant progress: a massive increase in high technology, the emergence of exigent customers, competitive markets, varied product quality, and random demands required the collaborations of the inter-related aspects of production. The production, maintenance, and quality are the most critical aspects of the industrial system. We are interested in optimising maintenance that plays a critical role in customer satisfaction, sustainability, and the development of companies. Our study is centred on developing production and maintenance integrated into a control chart of quality policy. We propose new integrated maintenance strategies with an in-depth analysis of the continuous production process reliability improvements and treated under customer requirements (Service, quality, and cost) constraints. The integration and optimal coordination of these factors of production is not easy and represent a challenge for industrial companies, and are more challenging with multi-assignable causes of production process variation. To address this problem, this research work employed the use of a control chart tool in combination with the AFNOR principles known as Rule of seven as involved in quality management. To monitor, analyses and direct appropriate maintenance actions for continuous system reliability improvements along the different multiple process scenarios as decision levels. We use the interactions between the production process and product quality for strategies of maintenance which reduce the failure of the production system by improving process reliability and reducing the no conformal products. The study Significantly focused on quality, quality tools, and their applications in production and maintenance control. The technique we used to optimise the maintenance and quality control of an integrated production system is a control chart tool based on statistical measurement and analysis of quality parameters. We model different production problems and develop a control policy for randomly failing production systems that must satisfy customer requirements dynamically throughout the finite production horizon. We introduced a mathematical model to minimise the total costs of production, inventory, maintenance, and quality control. The optimisation of the maintenance strategy was integrated into a control chart tool information. Based on the production rate variation and its impact on machine degradation the number of maintenance, times, and intervals needed for prudent decision-making is determined by the developed algorithm. In this context, this research presents the derivation for different cases of all the probabilities for the process to be in or out of control, the average run lengths, and the restoration cycle durations. Based on the degradation factor, new failure rate equations are formulated, and then the average failure rate for each case, we formulated different maintenance cost optimisation models. The proposed approach is useful for precise calculation and minimisation of the total maintenance cost. Which optimises total production cost considering all possible production process statuses due to multiple causes. Our work contributes to the emergence of quality management and performance improvement techniques that will contribute to the development of production companies

A TPM é uma abordagem de Melhoria Contínua reconhecida para o desenvolvimento de estratégias organizacionais, otimização do processo e o aumento de competitividade. Porém, durante sua implementação ocorrem muitas falhas e os resultados não ocorrem da maneira esperada. Para reduzir estas falhas, esta pesquisa tem como objetivo apresentar os Fatores Críticos de Sucesso (FCS) na implementação da TPM em um grupo de empresas brasileiras vencedoras do prêmio TPM Awards. Os FCS foram identificados através de uma pesquisa exploratória em casos de implementações bem sucedidas. Após identificados, estes fatores foram priorizados pelo método de Análise Hierárquica de Processo (AHP), por especialistas na metodologia TPM. As análises demonstram claramente, que o sucesso da metodologia TPM depende fortemente dos esforços dos gestores das empresas, principalmente a alta gestão. Desta forma, são apresentados os elementos fundamentais em que a gestão deve se concentrar em cada uma das quatro fases do programa. Este processo pode auxiliar os gestores a dar ênfase sobre os FCS e a identificar quais erros devem ser evitados para aumentar as chances de sucesso do programa da TPM.The TPM is a Continuous Improvement approach recognized for developing organizational strategies, process optimization and increased competitiveness. However, during its implementation many failures occur and the results do not occur as expected. To reduce these flaws, this study aims to present the Critical Success Factors ( CSFs ) in the implementation of TPM in a group of Brazilian companies winning the award TPM Awards. The FCS were identified through an exploratory research on cases of successful implementations. Once identified, these factors were prioritized by Analytic Hierarchy Process method (AHP), by experts in the TPM methodology. The analyzes clearly demonstrate that the success of TPM methodology depends heavily on the efforts of corporate managers, especially top management . Thus, the key elements that the management should focus on each of the four phases of the program are presented. This process can help managers to give emphasis on the FCS and identify what mistakes should be avoided to increase the chances of success of the TPM program.
