Full textAbstract:
The Production Manager at Atlas Copco AB Craelius wants to adopt a lean approach to become more competitive. This thesis is an exploratory study of the subject and what it means for the business activity and its implementation process. The objective is to provide a basic understanding of lean to the company, and what this means for Atlas Copco AB Craelius. The report describes the industrial revolution in brief. This is because the company itself must understand where certain ways of looking at production management is derived from. Furthermore, it provides an understanding of Lean's origins. The report describes lean principles and outline, some of the lean tools and methods as well as what these mean for Atlas Copco Craelius AB. The focus of the report is on education and the importance of management's knowledge and understanding of the subject. At the end of the report an adequate but overall implementation program is presented as well as a few examples of possible improvements. The thesis is based on a basic literature review of production management and lean. To get a general understanding of the business, I studied the assembly for a few days, talked to the staff, participated in the daily pulse meetings and participated in the production office Friday meetings. I did a study at Atlas Copco Tools AB to learn how they managed the implementation of lean there. Furthermore, personal experience from previous training, work and study has influenced the report.

Previous issue date: 2009-07-14In the current global scene, where the competition is increasing, it distinguished the great vehicles manufacturers dispute. The first in this ranking is Toyota Motor Company, a Japanese manufacturer who constructed a successful history since the postwar crisis period in Japan and assumed the world-wide sales leadership in 2007. This system production benchmarking is widely accepted and it is explored by the whole world assembly plants, even so its application doesn t occurs in the same standards of Toyota, what means partial implantations, mistakes in the concept or hybrid solutions that alternate between a production system and another one. This work makes an analysis on the process of lean production implantation applied in a French automobile company. The objective of this work is to identify level of adequacy of the company analyzed in relation to the rules and lean production tools in its productive process. To reach this objective company employees interviews is used, the author direct observations, searches in internal organizations documents and theoretical survey of the study object, searching to identify the employees knowledge level and the existing practical in the company that is not lined up to the lean production principles.

Full textAbstract:
Dans cette thèse, après avoir expliqué l'historique et les concepts principaux de l’organisation lean dans différents contextes, le monde des systèmes complexes est exploré, puis il est montré pourquoi le lean est lui-même un système complexe. Un modèle novateur du lean est proposé sous forme d'ontologie, le Lean Organization Framework (LOF), qui peut être appliqué à toutes les formes d’organisations. Le LOF est testé avec celles qui ont déjà été explorées, proposant ainsi des pistes d’amélioration (lean pour la fabrication, pour l’IT, pour les soins de santé, pour la fonction publique, pour les organisations non gouvernementales, pour les start-ups et pour l’éducation). Il peut également être appliqué à de nouveaux domaines d’activités avec l’aide d’experts dans ces domaines, une approche montrée avec les exemples nouveaux d’une fondation lean et de l’architecture d’entreprise lean (Lean EA) mais aussi en comparant l’organisation lean au système immunitaire, un exemple bien connu de système complexe. Ensuite, un modèle de processus lean est proposé, présentant les propriétés émergentes d’un système complexe, le hoshin kanri (gestion des objectifs de l’organisation), y compris dans sa dimension culturelle. Les résultats de son expérimentation pratique avec l’application eHoshin sont discutés et un premier prototype en open source est présenté, déjà utilisé à ce jour par une centaine d’organisations dans le monde. Une seconde expérimentation plus robuste dans l’industrie (Toyota, dans plusieurs fonctions et entités juridiques) est exposée. Le modèle théorique est enfin amélioré sur base des résultats obtenus. En annexe, les concepts du lean sont expliqués avec leur application à six domaines de connaissance différents et les programmes de simulations sont listésIn this thesis, after explaining the history and main concepts of the lean organization in various contexts, the world of complex systems is explored, then it is shown why the lean organization is itself a Complex System. A novel model of lean is proposed as an ontology, the Lean Organization Framework (LOF), which can be applied to all forms of organizations. The LOF is tested with those already explored (Lean Manufacturing, Lean IT, Lean Healthcare, Lean Government, Lean NGO, Lean Start-Up, Lean Education) and proposes ways to enhance them. It can also be applied to new domains with the help of subject matter experts, an approach that is checked with the novel cases of a Lean Foundation and Lean Enterprise Architecture (Lean EA), but also with the comparison of the lean organization with the immune system, a well-known Complex System example. Then, a model of lean process presenting the emergent properties of a Complex System is proposed: the hoshin kanri, or management of the organization objectives, including in its cultural dimension. The results of its practical implementation with the eHoshin application are discussed and a first open source prototype already used by around one hundred organizations in the world is explained. A second, more robust implementation in the industry is presented (at Toyota, extended to several departments and legal entities). Finally, the theoretical model is improved based on the experimentation results. In the appendices, the lean concepts are explained together with their application to six domains of knowledge and the simulation programs are listed

In 2005, Outokumpu began to implement its system of continuous improvement, OK> 1, at Avesta Jernverk. OK> 1 has not generated sufficient results on plant KPI:s. The purpose of this study is to identify the understanding, participation and commitment regarding to OK> 1, and to suggest some actions to make OK> 1 more successful with emphasis on these three aspects. The thesis shall also determine whether there are any differences in the attitude towards OK>1 between Blue Collars and White Collars.
The study consisted of a survey, and interviews. The output from these methods were processed and analyzed and finally resulted in a SWOT – analysis and suggested actions for improving the understanding, participation and commitment towards OK>1. The thesis work also covered a literature study concerning Lean Production, to get a deeper understanding of how to implement Lean Production successfully.
The results of the survey pointed out that Blue Collars do not understand OK>1 as well as White Collars, and that they do not participate as actively as White Collars in improvement activities. To improve the results on plant KPI:s the thesis suggests following actions: education, simplification of methods and increased feedback from the management.

Dissertação apresentada para cumprimento dos requisitos necessários à obtenção do grau
de Mestre em Ciências Empresariais, ramo gestão de PMENesta época em que vivemos uma das mais graves crises económicas e a maioria dos mercados europeus e mundiais registam graves recessões, impõe-se um tempo de mudança de pensamento e de abordagem à gestão tradicional. Temas como a qualidade e o custo baixo adquirem relevância ainda maior na sobrevivência das empresas, visto que os mercados se encontram cada vez mais competitivos. Para isto, as empresas são forçadas a analisar com melhor detalhe e pormenor os seus processos e a redesenhá-los com vista à redução ou, em alguns casos, eliminação de tudo o que não acrescente valor para a empresa, ou seja, eliminação de desperdícios nos seus processos. A metodologia do sistema de produção Toyota embora iniciada e concebida no seio da produção, abrange todas as áreas de uma empresa, sendo transversal a toda a empresa desde a parte produtiva, administrativa, recursos humanos, qualidade, engenharia e até logística externa e interna. Esta ultima tem vindo a afirmar-se num contexto global, através da sua implementação em diversas empresas e consequente uso das suas ferramentas. Com isto, as empresas conseguem obter excelentes resultados na melhoria de qualidade, redução de custos, na relação com os seus clientes e até na melhoria de relacionamento interno entre os diversos departamentos. Esta dissertação pretende evidenciar através do estudo de caso único, como a aplicação de ferramentas e técnicas do sistema de produção Toyota no contexto real de uma empresa da indústria automóvel, que se encontra inserida num grande polo industrial de Setúbal como é o da Volkswagen Autoeuropa, pode proporcionar a criação e aumento de valor acrescentado e a eliminação de desperdícios nos seus processos. Para a realização deste estudo de caso da empresa Schnellecke recorreu-se ao estudo de inúmeras técnicas e ferramentas tais como a metodologia Lean, VSM, TPM, 5S, gestão visual, ferramentas da qualidade, os cinco porquês, poka yoke, sistema de controlo Kanban, processos uniformizados e folhas de processo, heijunka e Kaizen. Este estudo permite realçar a importância do sistema Toyota que se denota nos enormes ganhos obtidos tendo em conta os investimentos para a melhoria das situações.
Abstract: In the time that we live one of the most serious economic crises in which most European and world markets are experiencing severe recessions, managers are inevitably shifting the thinking and approach from the traditional management. Issues like quality and low cost acquire even greater importance in the survival of firms because markets are increasingly the competitive. To do this, companies are forced to examine with better detail their processes and redesign them with tools to reduce, or in some cases eliminate everything that does not add value to the company, or in other words the elimination of waste in their processes. The methodology of the Toyota production system although initiated and conceived within the production , covers all areas of a company , being cross functional throughout the company since production , administrative, human resources , quality, engineering, internal and external logistics. This has been asserting itself in a global context, with several companies implementing it and using their tools to obtain excellent results in quality improvement, cost reduction, better relationship with its customers and to the improvement of internal relationships between different departments. This dissertation intents to show how using the unique case study in the application of tools and techniques of the Toyota Production System in the actual context of a company from the automotive industry which is inserted into a major industrial center in Setubal as the Volkswagen Autoeuropa, can provide creation and increase of value added and eliminating waste in their processes. For the realization of this case study in the company Schnellecke resorted to the study of numerous techniques and tools such as Lean, VSM, TPM, 5S, visual management, quality tools, the five whys, poka yoke, Kanban control system, standardized processes and methodology sheets process, heijunka and Kaizen. This study allows us to highlight the importance of this Toyota system that denotes the huge gains made taking into account the investments of improving the processes.

Full textAbstract:
Syfte: Branschen tampas fortfarande med kvalitetsbrister och har därför börjat uppmärksamma de fördelar som följer med industriellt byggande och standardiserade arbetsprocesser. Med industriella arbetsprocesser kan företagen ge frihet till arbetare att få ansvara för de arbetsprocesser som de medverkar i, och således bidra till att de förbättrar lösningar och standardiseringar. Ett koncept som lämpar sig väldigt väl för detta är The Toyota Production system (TPS), också kallat Lean production. År 2016 utfördes en samling fallstudier bland Lean-arbetande byggföretag där de visade att kvalitet och strävan efter standardiserade arbetsprocesser var högt prioriterat. Lean production och dess processer i företag omfattar informations – och kunskapsöverföringar och kan vara svårt att tillämpa. Därför motiveras vidare forskning på tillämpbarheten av principerna och dess verktyg i byggföretag. Studiens mål är att analysera hur företag inom prefabindustrin som arbetar med Lean kan utveckla sitt förbättringsarbete i produktionsprocessen. Metod: Rapporten är en kvalitativ fallstudie utförd på Ulricehamns Betong AB. Studiens datainsamlingsmetoder har varit litteraturstudier, deltagande observationer, semistrukturerade intervjuer och dokumentanalyser. Resultat: Utifrån studiens analys kunde vissa problem i förbättringsarbetet identifieras, samt leda till en analys över hur det förbättras och göras mer kunskapsdelande. Det framkom att inställningen till förbättringsarbete varierade stort bland medarbetarna. En gemensam syn på förbättringsarbetets betydelse krävs för fortsatt utveckling, något som kan uppmuntras från organisationens håll tydligare. Genom rollen som handledare kan företag säkra att det arbetas efter standardiserade arbetssätt. Konsekvenser: Avgörande för ett kunskapsdelande och utvecklande förbättringsarbete är att alla medarbetare är motiverade till att bidra till en förbättring. För att motivera medarbetarna bör statusen på individuell kunskap följt av inställning till kunskapsdelande att höjas. Medarbetare ska ha tillgång till kontinuerliga förbättringsmöten eller andra forum där de kan utbyta erfarenheter och idéer. Begränsningar: Fallstudien har genomförts på ett företag som använder sig av Lean-konceptet. Studien begränsas till att endast behandla förbättringsarbete i produktionen av prefabricerade betongelement. Studien redogör alltså inte för hur andra prefab-företags förbättringsprocesser ser ut i produktionen.Purpose: The industry is still struggling with reoccurring deficits regarding quality and has therefore began to pay attention what benefits that comes with an industrial building process. With industrial building processes the companies using it can let the workers be in charge of their work processes that they find themselves in and thus help to improve and standardise them. A concept that fits these conditions very well is The Toyota production system (TPS), also known as Lean production. In the year 2016 several studies were made that showed that among Lean working construction companies it was the reach for higher quality and standardised working processes that was prioritized. Lean production and its processes contains a lot of information- and knowledge transfers and may be hard to practice in a company. Therefore further studies on how to implement these principles and tools properly are recommended. The aim with this study is to analyse how companies in the precast industry who works with Lean can evolve their continuous improvement process in the production process. Method: This report is a qualitative case study accomplished at Ulricehamns Betong AB. The chosen methods on how to collect data are literature studies, participating observations, semi-structured interviews and document analysis. Findings: From the analysis of this study some problems in the improvement process could be identified, but also how they could be improved and how they could be more knowledge sharing. It was shown that the will to participate in the improvement process did varied a lot among the co-workers. A common attitude for the importance of the improvement process is needed for the continuous development, something that can be more encouraged by the organisation. Through the implementation of a mentor the company can ensure that the production process is more standardised. Implications: The number one thing that is most important for an evolving and knowledge sharing improvement process is that the co-workers stay motivated to participate. To motivate them, the status of individual knowledge should be raised and heard. Furthermore they should have access to continuous improvement meetings or other forums where they can exchange experiences and ideas. Limitations: The case study has been accomplished at a company that are using the Lean concept. The study limits to only study the improvement process in the production process of precast concrete elements. Furthermore the study is focused on how one specific company uses their improvement process and not how other companies uses theirs.

Syftet med denna rapport är att kartlägga Scania Production System (SPS), hur det motiverades och implementerades inom Scanias organisation samt dra kopplingar mellan tidigare reformer och SPS. Vi vill ta reda på hur Scania lyckats skapa ett eget skräddarsytt produktionssystem som visat sig vara så framgångsrikt och hur detta infördes inom hela organisationen. SPS är ett resultat av Toyota och deras Toyota Production System (TPS) efter ett nära samarbete mellan Scania och Toyota sedan början av nittiotalet. Scanias värderingar, principer och prioriteringar beskrivs av SPS och har visat sig vara en av företagets konkurrensfördelar genom ökad effektivitet samt produktivitet inom produktionen. TPS fick mycket av sin inspiration av de tidigare reformerna Taylorismen och Fordismen ur rationaliseringsrörelsen. Detta genom Taylors idéer om standardisering och Fords löpandebands-princip. Toyota var även bland dem första att utforma och tillämpa de logistiska reformerna Total Quality Management, Lean Production och Just-In-Time i sitt produktionssystem. Reformer som används och är välkända inom många företag inte minst Scania och SPS. Rapporten uppfyllde sitt syfte genom intervjuer och analys av konceptlitteratur för att kunna konstatera att det finns en röd tråd inom företaget och att det finns en tydlig koppling mellan SPS och tidigare reformer. Avslutningsvis lyckades vi även analysera och dra slutsatser om hur SPS utformades, motiverades och implementerades. Utformningen av SPS gick till genom ett nära samarbete mellan ledningar på Scania och Toyota vilken Scania på så sätt kunnat ta inspiration ifrån och kunnat anpassa systemet efter Scanias kultur. Hur sedan SPS motiverades och implanterades föregick i en ledningsprocess som Scania tillämpade inom organisationen. Lösningen kom att bli avgörande för framtiden, ledarskapet. Man tillämpade ett nytt tankesätt genom hela verksamheten vilket har visat sig vara framgångsrikt.The purpose of this report is to map the Scania Production System (SPS), how it was motivated and implemented within Scania's organization, as well as linking previous reforms with SPS. We want to find out how Scania managed to create its own customized production system that proved being successful and how it was introduced throughout the organization. SPS is a result of Toyota and their Toyota Production System (TPS) following a close collaboration between Scania and Toyota since the early 1990s. Scania's values, principles and priorities are described by SPS and have proven to be one of the company's competitive advantages through increased efficiency and productivity in production. TPS received much inspiration from the earlier reforms of Taylorism and Fordism from the rationalization movement. This through Taylor's ideas about standardization and Ford's running band principle. Toyota was also one of the first to design and apply the logistics theory’s Total Quality Management, Lean Production and Just-In-Time in its production system. Reforms used and well known in many companies, not least Scania and SPS. The report fulfilled its purpose through interviews and analysis of conceptual literature to find that there is a red thread within the company and that there is a clear link between SPS and previous reforms. In conclusion, we also managed to analyse and draw conclusions about how the SPS was designed, motivated and implemented. The design of SPS was achieved through close collaboration between Scania and Toyota wires, which enabled Scania to inspire and adapt the system to Scania's culture. The way in which SPS was motivated and implanted preceded a management process that Scania applied to within the organization. The solution came to be decisive for the future, leadership. A new way of thinking was applied throughout the business, which has proved to be successful.

This thesis examines The Toyota Motor Corporation's core precepts, management principles, supply chain architecture, product development methods, leveraged practice of supplier partnerships and procurement practices, all of which are integral elements associated with the Toyota Production System, and assesses the scalability these elements for application in the commercial aerospace industry.The methodology used in this study includes an examination of basic concepts and practices that Toyota employs throughout its extended enterprise and which are being widely adopted throughout the automotive industry as well as other industries worldwide, based on a review of the open literature. The research also draws upon the author's first-hand exposure to Toyota's production system through field research involving benchmarking site-visits to Toyota plants, and makes use of extensive interviews conducted with both automotive and aerospace industry experts.The research reported in this thesis reveals that Toyota's Production System, as a mutually reinforcing set of principles, methods and practices, are indeed scalable to the aerospace industry and that one of the two commercial aerospace behemoths, Boeing and Airbus, has an opportunity to leverage them in order to obtain a clear and sustainable competitive advantage in the industry. This is possible, however, with an important caveat: the end-to-end enterprise transformation process would need to be based on adopting a long-term approach to renovating the current system, working closely with the supply chain partners, owning the change process, and holding steady over the longer-haul.

Full textAbstract:
Detta examensarbete har utförts vid Elitfönster AB i Vetlanda. Elitfönster AB är Sveriges största leverantör av fönster och fönsterdörrar.
Syftet med arbetet är att ta fram åtgärdsförslag för att minska ledtiderna, då korta leveranstider blir ett allt viktigare konkurrensmedel. Arbetet innebar en kartläggning av nuvarande produktionsflöde och identifiering av problemområden.
Arbetet genomfördes med hjälp av tidsstudier och intervjuer med arbetsledare och personal. Arbetet bygger även en hel del på observationer, iakttagelser och studerande av statistik.
I stora drag kan man dra slutsatsen att de långa ledtiderna beror på främst två orsaker;
• hyvelbanornas långa ställtider som medför körningar i veckosatser
• kvalitetsbrister och bristfälliga kvalitetskontroller samt trästycken som ”försvinner” längs förädlingskedjan. Detta leder till att order får ställas åt sidan i väntan på nya/omlackade bitar.
För att erhålla en reducering av produktionsledtiden bör Elitfönster AB i första hand;
• överväga att flytta ut ett eller två produktsortiment, vilket skulle medföra reducerade ställtider i hyvelbanorna och därmed en möjlighet att bryta ner veckosatserna i mindre satser.
• sträva mot att synkronisera de olika resursernas cykeltider mot takttiden.
• skapa stabila processer, det vill säga tillförlitlig utrustning och mångkunnig personal, för att kunna minimera buffertar och mellanlager.
• kontinuerligt kvalitetsarbete i form av leverantörssamverkan och kvalitetsutbildningar till personal.

Denna studie är utförd på ett företag i Helsingborg som heter Abdon Finax AB. Företaget startade med mjöltillverkning för att sedan introducera müslin till Sverige. Sedan dess har bolaget fortsatt växa. I dagens samhälle går utvecklingen fort fram. Globaliseringen innebär att konkurrensen ökar och företag tvingas att tävla med varandra om kunderna, vilka ständigt söker bättre kvalitet, lägre kostnader samt kortare ledtider. Detta samtidigt som företagen försöker tjäna mer pengar genom ökad lönsamhet genom bland annat effektivare flöden. På så sätt kan företaget minimera kostnaderna för att kunderna ska kunna tillgodoses samtidigt som företagen tjänar på det. ’’Ibland måste man vara liten för att springa om de stora’’ är ett av Finax valspråk. För att fortsätta ha chansen att springa om de stora krävs flexibilitet i produktionen för att möjliggöra kortare ledtider till kunderna. Syftet med studien har varit att analysera flödet av de glutenfria produkterna på Abdon Finax AB för att finna effektiviseringsområden. För att kunna göra detta har en flödeskartläggning gjorts. Denna gjordes med hjälp av observationer samt intervjuer på företaget. Efter en jämförelse mellan teori och empiri har sedan några kritiska punkter pekats ut för förbättring och effektiviseringsförslag har rekommenderats. Dessa förslag involverar standardisering samt sänkningsförslag på omställningstiderna allt för att företaget ska öka sin flexibilitet och kunna producera i mindre batcher. Vilket ska leda till att ledtiderna minskar och även lagerkostnaderna. I framtiden när ställtiderna har minimerats skulle det vara fullt möjligt att producera efter kundorder vilket minimerar riskerna för att kassera produkter samt minskar lagerkostnaderna ytterligare.

Full textAbstract:
Syftet med detta arbete är att få en bättre förståelse av vad Lean Production innebär, med dess ingående grunder såsom Toyota Production System (TPS), samt hur det implementeras rent praktiskt i industrin, där teorin bakom Lean Production sätts i verksamhet. Lean Production är en filosofi där man arbetar för att uppnå en så resurseffektiv produktion som möjligt, genom att bland annat minska på olika former av slöseri. För att gränsa av arbetets omfång, undersöks specifikt Scanias motoravdelning och hur deras implementering av Lean Production och tolkning av Toyota Production System ser ut. Arbetet utfördes både som en litteraturstudie, med vetenskapliga källor från KTH:s databas och litteratur inom Lean Production och Toyota Production, och fältstudie i form av en intervju med en anställd inom motoravdelningen på Scania, rundtur i produktionen samt föreläsning om Scania Production System (SPS). Toyota är grundaren bakom Toyota Production System, där de utvecklat ett unikt system som ger resultat i form av kvalité och effektivitet. Från att vara ett litet företag utvecklades de till värdens största bilproducent och är en av de främsta anledningarna varför Lean och TPS uppmärksammats så pass mycket. Toyota har 14 principer som berör deras filosofi, människor, processer och problemlösning där dessa principer anses vara till nytta för företag som söker att utveckla sitt företag, både inom service och tillverkning. Lean Production är en filosofi som härstammar från TPS, där man i huvudsak fokuserar på att eliminera sju olika typer av slöseri och istället tillföra mer värde till kunden. Resultatet av detta arbete har genererat en helhetsbild av vad Lean Production och dess grunder är och hur det implementerats i Scanias motoravdelning, där de utvecklat ett eget produktionssystem SPS, modulsystemet och individhanteringen. I SPS återfinns många av de begrepp som diskuteras i TPS och Lean Production och är också den väsentliga likheten mellan dessa tre produktionssystem. Det som skiljer Scania från TPS och Lean Production är främst individhanteringen och modultänket. Slutsatsen att Scania har en bättre anpassning efter Lean än vi tidigare trott och att deras arbete stämmer väl överens med vad Lean Production är idag.The purpose of this work is to gain a better understanding of what Lean Production entails, with its basic foundations such as the Toyota Production System (TPS), and how it is implemented practically in the industry, where the theory behind Lean Production is put into operation. Lean Production is a philosophy in which you work to achieve as resourceefficient production as possible, by among other things reducing various forms of waste. To limit the scope of the work, Scania's engine department is specifically investigated and how their implementation of Lean Production and interpretation of the Toyota Production System looks. The work was carried out both as a literature study, with scientific sources from KTH's database and literature within Lean Production and Toyota Production, and field study in the form of an interview with an employee in the engine department at Scania, a tour of the production and a lecture on the Scania Production System. Toyota is the founder of the Toyota Production System, where they developed a unique system that gives results in terms of quality and efficiency. From being a small company, they were developed into the world's largest car manufacturer and are one of the main reasons why Lean and TPS were noticed. Toyota has 14 principles that address their philosophy, people, processes and problem solving, where these principles are of benefitial to companies seeking to develop their business, both in service and manufacturing. Lean Production is a philosophy that originates from TPS, where it mainly focuses on eliminating seven different types of waste and instead adding more value to the customer. The result of this work has generated an overall picture of what Lean Production and its foundations are and how it has been implemented in Scania's engine department, where they developed their own production system SPS, the modular system and individual management. In the SPS, many of the concepts discussed in TPS and Lean Production are found and are also the main similarity between these three production systems. What distinguishes Scania from TPS and Lean Production is primarily individual management and the modular thinking. The conclusion is that Scania is better adapted to Lean than we previously thought and that their work fits well with what Lean Production is today.

Full textAbstract:
A primary role of the Incident Command System is to learn from past incidents, as illustrated by its origins in the wildland firefighting community. Successful emergency response operations under the Incident Command System has prompted its nationwide spread, this promulgation critically relies on the system’s capability to stabilize and continuously improve various aspects of emergency response through effective organizational learning. The objective of this study is to evaluate the potential to apply fundamental principles of the Toyota Production System (Lean manufacturing) to improve learning effectiveness within the Incident Command System. An in-depth review of literature and training documents regarding both systems revealed common goals and functional similarities, including the importance of continuous improvement. While these similarities point to the validity of applying Lean principles to the Incident Command System, a focus on the systematic learning function of the Incident Command System culminated in the discovery of gaps in approaches proposed by the Incident Command System framework. As a result, recommendations are made for adjustments in systematic problem solving to adapt Lean principles of root cause analysis and emphasis on standardization of successful countermeasures to benefit the system. Future recommendations are also proposed based on the author’s understanding of the system.

Full textAbstract:
This study consists of two studies around Lean. The studies are limited to two databases and three different sectors, the industry sector where Lean originated from, and the welfare and service sectors. The first study is a quantitative pilot study on published articles. The purpose was to get an understanding of what extent the different sectors get published, compared to each other. The result was illustrated in a graph where 40 articles per year were proportionally divided between the three sectors. The main study is a literature review where a scoring matrix was used to cull the selected articles. The remaining articles where compared to the “Toyota house” to answer the research questions: In what way has the definition of Lean changed from the manufacturing-based improvement philosophy it originated as, to the concept that is used in different sectors today? How does the specific sector affect the implementation of Lean, is there a difference in the Lean that is described in the literature compared to the Lean that is used in the welfare or service sectors? The study found in the chosen literature is that the sectors that are new at using Lean are using less of the tools available and in a smaller part of the organization, instead of using it on the whole organization. Many case studies where found that describes what tool was used, but not how they were used. One sector with many published articles was the construction sector, but they were overlooked due to the limitations of the study.Denna studie består av två undersökningar kring Lean. Undersökningarna är begränsade till två databaser samt tre branscher, industribranschen där Lean grundades samt välfärds- och tjänstebranschen. Först gjordes en kvantitativ förstudie av publicerade artiklar för att få en uppfattning kring hur många andelar av de olika branscherna artiklarna bestod av. Resultatet visades i form av en graf där 40 artiklar från varje år delades upp i de tre branscherna. Efter det gjordes en litteraturstudie med en bedömningsmatris för en utgallring av artiklar. Utvalda artiklar jämfördes därefter mot ”toyotahuset” för att svara på forskningsfrågorna: På vilket sätt har definitionen av Lean förändrats från den produktionsbaserade förbättringsfilosofin det ursprungligen var, till det uttryck som används i flera olika branscher idag? Hur påverkar branschen implementeringen av Lean, skiljer sig det Lean som beskrivs i litteraturen mot det Lean som används i välfärds- eller tjänstesektorn? Det vi kunde hitta i den utvalda litteraturen var att de branscher som är nya med Lean använder färre verktyg och på mindre delar av sin organisation istället för att göra implementeringen på hela organisationen. Vi hittade många ”case studies” som berättar att det använt verktyg men inte hur verktygen har använts. En bransch som det hittades mycket artiklar om men som sållades bort på grund av avgränsningen var Lean construction.

The objectives of this thesis were to identify the path of implementation of lean practices in the manufacturing industry located in a region of scarce resources from a developing country, to evaluate the insertion degree such means according certain control variables (company size, industrial sector and the main productive typology) as well as to evaluate the effects of the lean manufacturing implementation on the performance of the companies studied. By means of a Survey, it was possible to investigate the lean manufacturing implementation using robust statistical techniques to define the measurement model defined as the mean of lean manufacturing adoption by the industry researched and to evaluate the effect of such adoption on performance. The results show a high, but partial, degree of lean adoption, which is observed by the identification of its implementation path composed of six internal practices (Single-Minute Exchange of Dies, Human Resource Management, Continuous Flow, Total Productive Maintenance, and Statistical Process Control) and two external (Supplier feedback and Customer engagement). Two other important lean practices (Just In Time delivery and Supplier development) have not been implemented, probably due to the region and country characteristics in where the companies are located such as: remote suppliers and lack of transport/logistics infrastructure plus the great territorial extension. In addition, such adoption has occurred in a fragmented way, as from 36 operational measures that comprise the eight practices considered as the lean implementation path, 13 have not been implemented. Moreover, it was verified the degree of adoption of the lean practices changes according to the company’s size (bigger companies tend to incorporate more practices compared to smaller companies) and the industrial sector. However, there has been no variation in the degree of adoption considering the main productive typology. Finally, it was observed the Lean Manufacturing interrelationship model has a positive effect on operational, financial and environmental performances.
Os objetivos desta tese foram identificar o caminho de implementação de práticas Lean na indústria manufatureira localizada em uma região de recursos escassos de um país em desenvolvimento, avaliar o grau de adoção de tais práticas conforme determinadas variáveis de controle (tamanho da empresa, setor industrial e tipologia produtiva principal) e avaliar o efeito da implementação de Lean Manufacturing no desempenho das empresas pesquisadas. Por meio de um Survey, foi possível investigar a implementação da manufatura enxuta com o uso de técnicas estatísticas robustas para definição do modelo de mensuração estabelecido como o caminho de adoção da manufatura enxuta pela indústria pesquisada e avaliar o efeito de tal adoção no desempenho empresarial. Os resultados mostram um elevado grau de adoção do Lean, porém de forma parcial, evidenciada pela identificação do seu caminho de implementação, composto por seis práticas internas (troca rápida de ferramentas, gestão de recursos humanos, fluxo contínuo, manutenção produtiva total, processo puxado e controle estatístico do processo) e duas externas (feedback de fornecedor e envolvimento de cliente). Além disso, duas importantes práticas Lean (fornecimento Just In Time e desenvolvimento de fornecedores) não vem sendo implementadas, provavelmente em função das características da região do país onde as empresas estão inseridas, a saber: fornecedores distantes e falta de infraestrutura de transporte/logística somada a grande extensão territorial da região estudada. Além disso, tal implementação tem ocorrido de forma fragmentada, visto que dentre as 36 medidas operacionais que compreendem as oito práticas consideradas como o caminho de implantação do Lean, 13 não foram implementadas. Verificou-se também que o grau de adoção das práticas Lean muda conforme o tamanho das empresas (empresas maiores tendem a implementar mais práticas comparada às empresas menores) e o setor industrial. Entretanto, não houve variação no grau de adoção conforme a tipologia produtiva principal. Por fim, observou-se que o modelo estrutural de inter-relação de Lean Manufacturing, apresenta efeito positivo sobre o desempenho empresarial nos âmbitos operacional, financeiro e ambiental.

Full textAbstract:
Företag bör helst bara genomföra aktiviter som skapar värde för kunden. Ett värdeflöde är de processer som används när en produkt förädlas. Genom att göra en värdeflödesanalys går det att identifiera vilka aktiviteter som är värdeskapande respektive icke värdeskapande. Uppdragsgivarna för detta examensarbete vill genom värdeflödesanalys sänka ledtiderna och höja leveransprecisionen. Vi kommer att ge förslag på förbättringar som kan uppnå detta men också att undersöka värdeflödesanalys som verktyg när produktionsordningen varierar. Det gjordes genom vad vi kallar ”mjuk” värdflödesanalys. Från Habia Cables, som tillverkar specialkablar, affärsystem framkom att de flesta maskiner på avdelningen som observerades har förseningar under året (2012). Under våra observationer stod många maskiner stilla, främst av två anledningar: återkommande problem som var lätta att åtgärda eller så uppstod andra fel men som tog längre tid att upptäcka. På avdelningen fanns verktyg för att identifiera förseningar men de användes inte av personalen. Tidigare misslyckade 5S-implementeringar har gjort att personalen delvis är negativt inställd till nya implementeringsförsök eller andra förbättringsåtgärder. Ett sätt att bli av med återkommande problem med maskinerna är att börja använda ett fem varför-tänkande för att nå grundorsaken till olika problem. Att ledningen och personalen ser olika på saker är vanligt och beror ofta på dålig kommunikation så att problem inte kommer upp till ytan. 5S är inte bara ett sätt att få ”ordning och reda” utan kan stödja högre och jämnare resursutnyttjande, något som bättre förutsättningar att sänka ledtiderna och höja leveransprecisionen. Vi gjorde en ”mjuk” värdeflödesanalys. Med det menas att vi främst undersökte hur personalen arbetar och i lägre utsträckning själva maskinerna och lager. Med detta arbetssätt ökar vi också förutsättningarna att applicera våra förbättringsförslag på andra avdelningar på företaget. I vår ”mjuka” värdeflödesanalys identifierade vi flera faktorer som kan förbättras så att företaget fokuserar sitt arbete på att skapa värde för kunden och eliminera icke värdeskapande aktiviteter. Tydligt och engagerat ledarskap krävs för att åtgärder för verksamhetsförbättring ska implementeras med framgång. 5S kan vara ett sätt för att sänka ledtiderna och höja leveransprecisionen om det inte bara används för att få ”ordning och reda”. Ett annat sätt för att nå sänkta ledtider och höjd leveransprecision är att finna grundorsaken till problem. När produktionsordningen varierar och produkterna har hög grad av specialisering kan det vara mer fördelaktigt att satsa på en flexibel produktionsprocess än att anpassa flödet efter en eller några få produkter.Companies should focus on activities that create value for the customer. A value stream is the processes that are used to manufacture a product. Through value stream analysis, value creating and non-value creating activities can be identified. The aim of the company aim with this thesis is to decrease lead time and increase delivery precision. We will make suggestions on improvements to fullfill that aim but also examine how values stream analysis is used when the manufacturing order varies. This was be done with what we call “soft” value stream analysis. The business system of Habia Cable, a special cable manufacturer, revealed that most machines in the observed section of the factory had delays during the year (2012). During our observation, many machines were not running, chiefly of two reasons: recurring problems that were easy to fix or other problems but were harder to discover. There were instruments to identify delays in the factory but they were not used by the staff. Previous unsuccessful 5S-implentations contributed to a negative attitude towards new implementation attempts or other improvement projects. One way to eliminate recurring problems regarding machines is to start using five whys which helps reaching the root cause for different problems. It is common that management and staff have different views on things and the reason is often bad communication which leads to problems not resurfacing. 5S is not only a tool to “clean up” the factory. It can also be used to support higher and more consistent use of resources. We conducted a “soft” value stream analysis. By that, we mean that our research focused mainly on how the staff works and not as much on the machines and stocks. Through this way of working, the applicability of our suggestions for other departments in the company increases. In our ”soft” value stream analysis we identified several factors which can be improved so that the company focuses on creating value for its customers and eliminating non value-adding activities. Clear and committed leadership is required for measures to improve operations to be implemented successfully. 5S can be one way to reduce lead times and increase delivery accuracy if it is not only used to “clean up” the factory. Another way to reduce lead times and increase delivery accuracy is to find the root cause to problems. When the order of how at product is manufactured and the products are highly specialized, it can be better to invest in a flexible manufacturing process rather than adjust the manufacturing process for one or a few products.

Previous issue date: 2014-10-03The metallurgical Alfa has three areas of operations: the Port, the Refinery and the Smelter. The intermediate area produces alumina using steam as an energy source. This comes from two High Pressure Boilers that operate together and are essential for the full operation of the process, so it is necessary make it reliable equipment. With this in mind, Alfa industry bases its operations management in a Own Business System adapted guidelines of the Toyota Production System (TPS) and Total Productive Maintenance (TPM). So, this was seen as an opportunity for research, which was carried through the search for understanding of the Business System, the definition and understanding of the equipment, the realization of hiking equipment by a multidisciplinary team, with a survey of existing equipment failures, by mapping the current situation, identifying the losses associated with the faults previously raised by raising costs and monitoring focused on technical resolution and human reliability during maintenance activities, which were carried out to remedy or minimize failures, as described. Thusthere was a reduction in production losses around 3484.28 t SGA/year and 304.526,07 US$/year of 2011compared to the year 2012. And also proof that the boiler reaches 100% of their operational availability and yes, they can become confident with the implementation of continuous improvement.
A indústria metalúrgica Alfa possui três áreas de operações: o Porto, a Refinaria e a Redução. A área intermediária produz alumina utilizando como fonte de energia, o vapor. Este é oriundo de duas Caldeiras de Alta Pressão que operam juntas e são essenciais ao pleno funcionamento do processo, por isso é necessário torná-las equipamentos confiáveis. Com este intuito, a indústria Alfa alicerça sua gestão de operações em um Sistema de Negócios Próprio adaptado das diretrizes do Sistema Toyota de Produção (STP) e da Manutenção Produtiva Total (MPT). Assim, esta situação foi vista como oportunidade de pesquisa, a qual foi realizada através da busca pelo entendimento do Sistema de Negócios, pela definição e entendimento dos equipamentos, pela realização de caminhadas pelos equipamentos com equipe multidisciplinar, pelo levantamento das falhas existentes nos equipamentos, pelo mapeamento da situação atual, pela identificação das perdas associadas as falhas levantadas anteriormente, pelo levantamento de custos e pelo acompanhamento focado na resolução técnica e na confiabilidade humana durante as atividades de manutenção, as quais foram realizadas para sanar ou minimizar as falhas, já descritas. Desta forma, houve uma redução nas perdas de produção em torno de 3.484,28 t SGA/ano e 304.526,07 US$/ano do ano de 2011 em relação ao ano de 2012. E também a comprovação que as caldeiras alcançam 100% da sua disponibilidade operacional e sim, podem tornar-se confiáveis com a implementação da melhoria contínua.

Titel: PMC WAY – Vägen till effektiv produktion
Problem: Hur kan PMC AB använda sig av Lean production-konceptet för att få en mer produktiv och effektiv produktion?
Syfte: Syftet med denna uppsats är att på uppdrag av PMC AB genomföra en studie om konceptet Lean production, för att sedan ta reda på hur PMC AB kan använda sig av detta koncept i sin produktion för att bli mer effektiva och produktiva.
Metod: För att genomföra studien har primär- och sekundär data använts. Den primära datan har samlats in genom intervjuer med personer på PMC AB samt observationer i produktionen. Den sekundära datan består av information insamlad från litteratur, artiklar, Internet och broschyrer.
Resultat: Studien visar att Lean production inte bara är användbart i stora österländska företag såsom Toyota, utan går att implementera på alla olika sorters företag. Konceptet betonar dock vikten av att grundligt gå igenom alla delar av företaget och inte glömma någon. Toyota Ways fyra huvudområden tar upp just alla företagets delar, vilket har gjort att modellen blivit så framgångsrik. De fyra huvuddelarna är filosofin, processerna, medarbetare och partners samt problemlösning. Alla fyra huvudområden är viktiga på olika sätt, men utan den långsiktiga filosofin blir det svårare, om inte omöjligt, att uppnå framgång med konceptet. Den långsiktiga filosofin sitter tätt ihop med att företaget måste få med sig alla medarbetare i detta långsiktiga tänkande. Ledarna måste få medarbetarna motiverade och känna ett engagemang gentemot verksamheten och inte bara ser det som ett arbete. Kan ledarna få medarbetarna motiverade går det lätt att förbättra processerna och få bort allt slöseri i företaget. Detta kan dock endast göras om medarbetarna och ledarna själva blir problemlösare och lär sig se och lösa problem. Därför måste företaget få dem att inse att problem är något bra och något som endast kan göra företaget bättre. Genom att använda sig av denna modell har vi kunnat få fram vad som är viktigt för PMC att tänka på för att får en mer produktiv och effektiv produktion. Vi har analyserat fram hur PMC kan förbättras, och lämnat förslag till ledningen som nu får ta över arbetet med att genomföra dessa förbättringar.

Full textAbstract:
Inom byggbranschen är det av vikt att hitta arbetssätt som på lång sikt sänker byggkostnaderna för att på så sätt kunna producera en vara som kräver mindre förbrukning av resurser men som även fortsätter vara konkurrenskraftig. Syftet med detta examensarbete är att undersöka hur medarbetarna vid Skanskas byggprojekt "Trädgårdarna" i Boglundsängen, Örebro kommun, arbetar för att minimera slöserier (icke värdeskapande aktiviteter). Syftet är även att identifiera vanliga slöserier som förekommer, både generellt på byggarbetsplatser men i synnerhet på byggprojektet "Trädgårdarna", samt att slutligen komma med förslag på åtgärder för att mini-mera dessa slöserier. Arbetet grundar sig på en kvalitativ metod i form av intervjuer och obser-vationer. När detta arbete skrevs var produktionen i ett tidigt stadie. Arbetets resultat påvisar att det finns både styrkor och brister gällande hur arbetet på "Trädgårdarna" fortskrider. Även fast produktionen i skrivandets stund inte har kommit så långt på projektet framkommer det av resultatet att personalen värdesätter ordning och reda och försöker upprätthålla detta genom olika tillvägagångssätt. Överlag arbetar personalen bra med att minska slöserier på arbets-platsen. De slöserier som har uppstått beror främst på brister i projekteringen och/eller produktionsplaneringen. För att minska slöserierna och upprätthålla ett effektivt arbetssätt är det av stor vikt att ha en genomarbetad projektering, genomföra arbetsberedningar på så många moment som möjligt, ha god ordning och reda på arbetsplatsen, ta tillvara på personalens kunskap och engagemang samt att utnyttja någon form av samordnad leverans för att minimera lagerhållningen och väntetiderna.In the construction industry it is important to find ways of working that in the long term lowers construction costs so as to produce a product that requires less consumption of resources, but which also continues to be competitive. The purpose of this thesis is to investigate how employees at Skanska's construction project "Trädgårdarna" in Boglundsängen, Örebro, work to minimize wastes (non value-adding activities). It also seeks to identify common wastes that occur, both generally on construction sites but in particular on the building project "Trädgårdarna", and finally to come up with suggestions on measures to minimize these wastes. This thesis is based on a qualitative method in the form of interviews and observations. When this thesis was written production was at an early stage. The results of this thesis demonstrate that there are both strengths and weaknesses regarding how work on "Trädgårdarna" is pro-gressing. Although the production was in an early stage, during the time of writing this thesis, the results show that the staff appreciates orderliness at their workplace and try to maintain this through different means. Overall, the staff work well to reduce wastage in the workplace. The wastes which have arisen primarily did so due to deficiencies in the design and/or production planning. To reduce the wastage rate and maintain an effective work it is of great importance to have a well-planned design, to implement work preparations as frequently as possible, to have an orderly workplace, to take advantage of the staff's knowledge and commitment and to use some form of coordinated delivery system to minimize inventory and waiting times.

This research aims to elaborate directives influenced by the principles of management of the Toyota Production System (TPS) for the design of the industrial architecture project. The purpose is to contribute with the elaboration of the factory architecture project using orientations based on the positive results of TPS. The methodological approach chosen for the development of this dissertation was the Design Science Research Methodology (DSRM), directed to technological research. The research explains that the production management is based on principles that need a correct organization of the space, study and methodologies in the design of the architecture projects of the factory buildings. In addition, the work considers the possibility of the designed physical space to contribute with solutions to the organizational demands and to facilitate the application of the productive system. The research is focused in the relations between the guiding principles of the TPS and the complexities of the factory projects. With the application of DSRM, at first a theoretical review on the factory building and the most relevant principles of the TPS is carried out. Then an analysis of the relationship of the two concepts from a conceptual map establishes the design and development of a proposed Toyota Architecture Directive (DAFT). In a third moment, this set of directives is submitted to the eyes of eight experts working in the area of architecture and industry, through semistructured interviews. This evaluation allows the refinement of the set of 14 directives (DAFT) for final presentation. In the discussion of the directives by the experts interviewed the opinions link the production management with the need to study the factory space as a whole, in an interactive way. At all times, it is evident that the complexity of projects and manufacturing facilities requires specific study methodologies to solve organizational problems. As a result of the research, we also obtained evidence that the directives from the TPS tools, for the most part, can be applied in several industrial projects, considering that some experts work with other systems and considered them relevant. In this way, the DAFT can represent to the organizational challenges a possible discussion proposal to assist in the decision making in all stages of the design of the industrial architecture project.
Esta pesquisa tem como objetivo elaborar diretivas influenciadas pelos princípios de gestão do Sistema Toyota de Produção (TPS) para a concepção do projeto de arquitetura fabril. O propósito é contribuir na elaboração do projeto de arquitetura fabril com orientações baseadas nos resultados positivos do TPS. A abordagem metodológica escolhida para o desenvolvimento deste trabalho foi a Design Science Research Methodology (DSRM), direcionada para pesquisas tecnológicas. A pesquisa explicita que a gestão da produção é baseada em princípios que necessitam de uma correta organização do espaço, do estudo e de metodologias na concepção dos projetos de arquitetura dos edifícios fabris. Além disso, o trabalho considera a possibilidade do espaço físico projetado em contribuir com soluções para as demandas organizacionais e facilitar a aplicação do sistema produtivo. A pesquisa é subsidiada nas relações dos princípios norteadores do TPS e nas complexidades dos projetos fabris. Com a aplicação da DSRM, primeiro é realizada uma revisão teórica sobre o edifício fabril e os mais relevantes princípios do TPS. Em seguida, uma análise da relação dos dois conceitos a partir de um mapa conceitual estabelece o design e o desenvolvimento de uma proposta de Diretivas de Arquitetura fabril Toyota (DAFT). Em um terceiro momento, este conjunto de diretivas é submetido ao olhar de oito experts atuantes na área da arquitetura e industrial, por meio de entrevistas semiestruturadas. Esta avaliação, em um quarto momento, permite o refinamento do conjunto de 14 diretivas (DAFT) para apresentação final. Na discussão das diretivas pelos experts entrevistados, as opiniões fazem a ligação da gestão da produção com a necessidade do estudo do espaço fabril como um todo, de forma interativa. Em todos os momentos fica evidenciado que a complexidade dos projetos e das instalações fabris exige metodologias de estudo específicas para solucionar os problemas organizacionais. Como resultados da pesquisa também foram obtidas evidências de que as diretivas advindas das ferramentas do TPS, em sua maioria, podem ser aplicadas em projetos industriais diversos, considerando que alguns experts trabalham com outros sistemas e as consideraram pertinentes. Desta forma, as DAFT podem representar aos desafios organizacionais uma possível proposta de discussão para auxiliar na tomada de decisões em todas etapas da concepção do projeto de arquitetura fabril.

Full textAbstract:
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”.
La presente tesi, dopo una panoramica introduttiva su l’origine e l’evoluzione del Pensiero Snello e l’analisi di tutti i tools disponibili per combattere lo spreco; si propone di analizzare l’applicazione degli stessi in Gambro Dasco, multinazionale biomedicale leader nella vendita delle sue apparecchiature per dialisi.

Full textAbstract:
This master thesis is the last part of the master program Production Engineering and Management at the Royal Institute of Technology, KTH, in Stockholm. The thesis is conducted at Exeger Operations AB, in short Exeger. The company is in an expansion phase and wants to prepare for future production expansion. Thus, a simulation capability to test future production scenarios was desirable. The problem definition was defined by the company together with the authors and led to a literature study within simulation, TPS and Lean manufacturing. Following the literature study, a current state map was produced to achieve sufficient understanding of the production flow at the company. A simulation model was then built. The model was used to test three different ”what-if” scenarios. Buy or Optimize, Future ratio 3:1:1 and Buy or SMED. The authors’ findings in the Buy or Optimize scenario suggest that optimizing the process time in the printers is far better, from multiple perspectives, than investing in new machinery. A 3:1:1 ratio of printers, sinter 1 and assembly station was developed using the simulation model to achieve leveled production flow of these specific processes. Lastly, conducting a SMED on the sinter 1 machine, the setup-,and wait-times achieved a theoretical reduction up to 75 % by altering the SOP and allocating additional preparatory space, in accordance with Lean philosophy. This change would offer the same improvement to a full-scale production as investing in a new sinter 1 according to the simulation model. Future work may consist of Layout Planning and adopting the simulation model to new prerequisites.

Resumo: Este trabalho apresenta uma metodologia para o direcionamento de projetos de melhoria nas empresas com base nas ferramentas do Sistema Toyota de Produção. Muito esforço têm sido despendido pelas empresas para alcançar resultados significativos em projetos de melhoria justamente pela não utilização de métodos estruturados de direcionamento destes projetos. O modelo metodológico proposto utiliza a integração entre o Mapa de Fluxo de Valor, o Balanced Scorecard, e o guia de produção enxuta da empresa como ferramenta para garantir a melhor relação possível entre custo e benefício alcançado nos projetos de melhoria. A validação do modelo se dá através de um projeto de implementação coordenado pelo autor, que utiliza esta metodologia durante mais de um ano em uma empresa de autopeças, e ao final do trabalho apresenta os ganhos referentes à aplicação do método
Abstract: This work presents a methodology to drive business improvement projects based on Toyota Production System tools. A lot of efforts are being spent by the companies to reach significant results on improvements projects because they do not utilize structured methods to drive these projects. The methodological model proposed uses the integration between the Value Stream Map, the Balanced Scorecard, and the Lean Production Guide of the company as a tool to assure the best possible relation between cost and reached benefits on improvements projects. The validation of the model occurs through an implementation project coordinated by the author, who applied this methodology for more than a year in an auto parts company and at the end presents the gains related to the application of the method

Resumo: Este trabalho teve como objetivo avaliar a aplicação dos conceitos da Manufatura Enxuta em uma empresa do setor automobilístico. Esta aplicação se deu em duas áreas distintas da empresa, sendo uma delas uma máquina de forjar a quente, que apresentava aumento de demanda de 30% dos itens nela produzidos, e a outra uma família de peças responsável por grande parte do faturamento desta empresa, que não atendia às necessidades do cliente em termo de performance de entrega, com alto nível de atraso. Foram utilizadas ferramentas como a Análise dos Sete Desperdícios, Setup Rápido, Sistema Puxado e Mapeamento do Fluxo de Valores, todas suportadas pela metodologia DMAIC de implantação. Após a implantação das melhorias sugeridas em Workshops Lean por times multifuncionais, ocorreu a medição dos resultados. Para ambos os casos estudados, os resultados foram satisfatórios, como aumento do OEE, redução do Lead Time, aumento do nível de produção e redução dos tempos médios de setup, porém com discretas diferenças. Desta forma, no decorrer desta dissertação são abordados os motivos pelos quais os resultados finais foram diferentes e também o motivo pelo qual o Estudo de Caso foi o modelo de estratégia de pesquisa adotado
Abstract: This study aimed to evaluate the application of the concepts of lean manufacturing in a company of the automobile sector. This application was made in two different areas of the company, one was a hot forging machine, that there was a demand increase in 30% of the itens producedes on this machine, and the other was a family of parts responsible to much of the income from this company, that didn't attend the delivery performance requirements. For this study, some tools were used as the analysis of the Seven Wastes, Quick Setup, Pull System and Value Stream Mapping, all of them supported by DMAIC methodology. After the implementation of the suggested improvements from the workshops with multifuncional teams started to measure the results. For both studied cases, the results were satisfactory, as OEE increasing, Lead Time reduction, increased the production level and average setup time reduction, however with slight differences. Thus, throughout this dissertation examines the reasons why the final results were different and also why the case study was the model search strategy adopted

Previous issue date: 2008-10-27Since first contact with Lean Manufacturing, western scientists have been struggling to understand the philosophy and replicate Toyota s benefits. Lean at the industrial environment is well explored and understood. The actual challenge is the expansion to the non-manufacturing arena. This work uses Lean Thinking to solve a sales problem by using its basic principles to reduce demand variability at direct business-to-consumer sales of complex-type buying behavior. Following methodological considerations, the first step towards making up for the research problem was to set Lean Thinking as a Research Program in the molds of Lakatos (1979) providing a common ground for the expansion of its concepts. Second step, covered at chapter three and with rhythm as its fundamental element, was the construction of the proposed method aimed at stabilizing demand through expanding Lean Thinking s principles to sales front-office. This method has been illustrated at chapter four by describing the implementation of the seven proposed steps in a real company over a two year period. Despite this work has not used quantitative or experimental approaches, the proposed method seems to have potential of reducing demand variability in direct business-to-consumer sales. Future research work might test effectiveness of the method by applying it at similar to studied companies or use the Research Program elaborated at chapter two as a foundation to expand Lean Thinking to other non-manufacturing areas, be them sales-related or not.
Desde os primeiros contatos com a Manufatura Enxuta, pesquisadores do mundo ocidental vêm se esforçando para entender esta filosofia e replicar os benefícios obtidos pela Toyota. A aplicação no ambiente industrial já foi bastante explorada, sendo que o desafio atual é o de expandir seu uso a ambientes não-manufatureiros. Este trabalho trata da aplicação da Mentalidade Enxuta a um problema de vendas, utilizando seus princípios básicos com o objetivo de estabilizar a demanda em vendas diretas empresaconsumidor com comportamento de compra tipo complexo. Feitas as considerações metodológicas, o primeiro passo no sentido de realizar o problema de pesquisa foi a caracterização da Mentalidade Enxuta como um Programa de Pesquisa, nos moldes sugeridos por Lakatos (1979), construindo a base para expansão dos seus conceitos. O segundo passo, desenvolvido no capítulo três e tendo o estabelecimento de ritmo como elemento central, foi a construção do método proposto para estabilizar a demanda por meio da expansão da mentalidade enxuta para o front-office da área de vendas. Este método proposto foi ilustrado no capítulo quatro por meio da sua aplicação a um caso prático, no qual uma empresa implementou os sete passos propostos ao longo de dois anos. Apesar desse trabalho não utilizar abordagens quantitativas ou experimentais, o método proposto parece ter potencial para estabilizar a demanda em vendas diretas empresa-consumidor. Trabalhos futuros podem testar a eficácia do método aplicando-o em empresas similares à estudada ou utilizar o programa de pesquisa estruturado no capítulo dois como base para a expansão da mentalidade enxuta a outras áreas nãomanufatureiras, seja a de vendas ou não.

Lo studio di cui tratta l’elaborato si sviluppa durante il periodo di tirocinio in azienda. L’obbiettivo del lavoro si concretizza nell’applicazione di metodologie lean all’interno del magazzino Toyota TMHE di Bologna, per ottenere un miglioramento in termini di bilanciamento dei flussi presenti e quindi di efficienza operativa dello stesso. Nello studio vengono descritte le metodologie e gli aspetti che stanno alla base delle scelte effettuate durante la riprogettazione del magazzino, evidenziando tutti i fattori che ivi concorrono. Il primo passo è un dettagliato periodo di analisi dello stato attuale del magazzino, in cui si cerca di individuare tutti i muda, ovvero gli sprechi, che concorrono nel generare inefficienza. In seguito, viene determinato un set di soluzioni possibili alle criticità individuate, all’interno del quale vengono selezionate le soluzioni più congrue alle esigenze dell’azienda, tenendo conto dei vincoli di tipo strutturale e informativo che concorrono alla complessità del problema. Il progetto viene poi concretizzato implementando effettivamente la soluzione in azienda, controllandone gli effetti sui flussi, sulle strutture presenti e sui lavoratori. Infine, viene verificata la sua efficacia tramite l’utilizzo di strumenti qualitativi e quantitativi, che si conclude con il riscontro di un miglioramento in linea con gli obiettivi prefissati.

Full textAbstract:
Background: There are various manufacturing methods and systems in automobile
industries throughout the world. Of these, many practice lean manufacturing methods.
The most effective and influential to all of these methods is the “Toyota Production
System” (TPS). The TPS was invented by Toyota's founding fathers in 1930 in Japan. The
TPS continuously evolves making it a benchmark for the manufacturing, product
development or any other sector of industry. It is fully based on “Socio-Technical”
systems in a continuously changing manufacturing environment. It is about learn
through doing and also about tacit knowledge and not explicit procedural knowledge.
Outcome: The Toyota Production System is called “The Toyota Way” and it actually
gives you a roadmap or more of a compass to set your direction and helps you steer
your own course. Toyota has internally developed simple but effective tools and
consistently trains their team members to implement those in all aspects of
manufacturing and designing their vehicle. For example, Toyota has developed Kaizen or
continuous improvement through which they eliminate waste that adds cost without
adding value no matter how small it is.
Toyota is known for the quality of their products. Not surprisingly their product is made
at a significantly lower price within a given segment of the auto market. It is a result of
hard work, innovation, and a Japanese work culture of generations at Toyota all across
the world.
Conclusions: Through theoretical analysis backed by my personal observations as an
employee and from the sales figures of Toyota automobiles, I firmly believe that Toyota
backs up its philosophy of long term benefits over short term financial goals. The right
processes will produce right results. It is also one of the top companies among their
group of long term suppliers as Toyota challenges them and helps them to improve.

The meaning of Just-In-Time (JIT) is to produce the necessary amount of product at the necessary time in order to fit the market demands of small amount and large variety. The leveling production of JIT is the technique to meet this kind of demand. The leveling production is achieved through roughly adjusting the monthly demand and fine adjusting the daily demand. However, the leveling production degree will affect the operation performance of a manufacturing system. It is important to investigate the affect leveling production degree on the operation performance. Unfortunately, literature reviews show that just a few researches investigate the leveling production degree. The objective of this research is to investigate the affect of leveling production degree on Toyota production system (TPS) performance by a dynamic simulation model. This research finds that the selection of the leveling production degree is not an optimization problem, but a trade-off problem. The selection of the better leveling production degree depends on the decision-maker’s business philosophy and valve criteria. A company that adopts the TPS will make its decision based on the smallest work-in-process (WIP). Under this condition, a higher degree of leveling production, smaller set-up time and fewer product defect rate will be. Suggested to use in the TPS.

After two energy crisis, Toyota Motor Corporation continued to thrive regardless the high-variety, low-volume marketing limitation. Thereafter, Toyota Production System(TPS) started to attract attentions, later becoming a new manufacturing paradigm. In 1990, the essence of TPS was introduced to the West through the IMVP led by MIT as “Lean Production.” After the IT Innovation bubbles and financial crisis, Lean Production has become a significant doctrine in the global manufacturing systems. When various global industries vied to learn TPS from Toyota co., applying TPS or Lean Production have resulted diverse means and end in different regions and conditions. However, prior studies have treated them as the same manufacturing theory, and the discussion regarding their reasoning and contexts was never being made. Therefore, this research aims to clarify the differences between TPS and Lean Production, and the field applications under different conditions. Starting with the theoretical analysis on backgrounds, contexts and implication differences of TPS and Lean Production, this study also carries out a theoretical research of 47 relative reading materials on these two manufacturing theories. Furthermore, through characterizing these two theories into four dimensions: ideology of deep-manufacturing, revolution, continuous improvements, and respect for people, this research defines TPS and Lean Production as J-type and L-type practical theory respectively. Lastly, case studies on successful Lean Revolutions in two enterprises are also designated to test and amend these theories. As a result, two discoveries were being made. Firstly, when applying these two practical theories, there are constraints in adaptability. Secondly, various characteristics have been crisscrossed in practice: For example, efficiently bringing in experts accelerates revolutions; nevertheless, allowing the participation of all members deepens revolutions. Although these two theories were developed under different backgrounds and perspectives, and have different characteristics and suitable conditions, they can still be interconnected strategically to achieve complementing outcomes.

Global economy changed rapidly during past three decades, and enterprises are all seeking to survive in the fast change environment by increasing core competency. Enterprise also agrees that core competency should be DNA of company culture which consist of “innovation”, “continuous improvement”, and “sustainability” inside. This is so-called Toyota Production System (TPS) which was invented by Taiichi Ohno, the Former Vice President of Toyota (car maker). He who invented TPS in order to survive the rapid-changed market and grow up from time to time, therefore built up a brand new production management technique and it’s methodology are “management concept”, “production organization”, “logistic control”, “quality control”, “cost control”, “inventory management”, ‘on-site management”, “real-time improvement” etc. Many scholars keep addressing research of how to transform those improvement activities and implementations into corporate culture and KPI, meanwhile, feel deep sympathy with spirit of “non-conservative” in TPS improvement activities. Industry 4.0 is a dreamy way for corporate to build up perfect factory, but need to input more resources in terms of operation and technique. The aim of this study is to establish an intelligent production process. However, improvement or achievement of Industry 4.0 will not happen overnight. Thus, in this research, we will aim at improvement from small scale to large scale, from material flow and information flow then automation,、production leveling,、Just In Time、pull-production, and end up to intelligent production process. We also wish that this research could bring contribution to Industry 4.0 with TPS’s “non-conservative” spirit.

The Toyota production system is already widely known, and many arguments have been supported by empirical cases. However, many prior studies lack a comprehensive consideration of the system improvement process, resulting in a gap between expected and actual results. In the past, improvements were made privileging the value stream mapping exclusively, which presented system effectiveness in a static manner and was unable to show dynamic changes in the system. The present study combined the value stream mapping and system simulations to observe the influence of improved items on the overall production system through simulated evaluations of improvement results in advance. This process reduced the risk and cost of production failures and demonstrated the feasibility of conducting simulated improvement evaluations. Additionally, prior cases were studied through prescriptive analytics to evaluate improvement results given different situational changes. The study offers suggestions for improvement for various situations. The research projects conducted by scholars Wei-Jie Wu and Guo-Jie Ye were revised and updated. Improved items in the research included continuous flow operations, combined workstations, multi-skill, and the Supermarket pull system. Finally, the study also provides improvement guidelines for management regarding inventory quantity and reduction in processing time when customers place orders. When the order arrival frequency is an fixed situation, the results indicated that the optimal solution could improve the order lead time about 93% and improve the WIP about 84%. When the customer order arrival frequency is an index situation, improves the order lead time about 84% and improves the WIP about 76%.

Dissertação de Mestrado em Engenharia e Gestão Industrial apresentada à Faculdade de Ciências e Tecnologia da Universidade de CoimbraCom a globalização, o preço dos produtos passou a ser estipulado pela mercado, fazendo aumentar a competitividade entre as empresas. Assim, para garantir o lucro que as empresas desejam, estas passaram a apostar em métodos que reduzam o custo associado ao produto, eliminando ou minimizando ao máximo as atividades que não acrescentam valor ao produto. O presente documento foi desenvolvido em cooperação com a empresa Toyota Caetano Portugal, SA, para a implementação da metodologia TPS (Toyota Production System) na linha de produção da soldadura da carrinha Dyna. Esta metodologia é direcionada para a melhoria contínua e otimização de processos, através da normalização dos trabalhos, da definição da sequência das tarefas e da eliminação dos desperdícios. Primeiramente, são descritos a filosofia Toyota Production System e os 7 desperdícios que Taiichi Ohno. Em seguida, são apresentados os resultados do estudo realizado com base nesta metodologia de alguns dos postos de trabalho da linha de produção da soldadura.
With globalization, the price of products has become determinate by the market, increasing competition among companies. Thus, to ensure the profit that companies want, they started to bet on methods which reduce the costs associated with the product, eliminating or minimizing the maximum activities that add no value to the product. This document was developed in cooperation with the company Toyota Caetano Portugal, SA, for the implementation of the methodology TPS (Toyota Production System) in welding production line of minivan Dyna. This methodology is directed to continuous improvement and process optimization through standardization of work, the definition of the sequence of tasks and eliminating waste. First, are described Toyota Production System philosophy and the 7 wastes that Taiichi Ohno. Then, the results of the study based on this methodology of some of the jobs of the welding production line are presented.

The amount of automobiles is increasing recently; however, the increase isn’t for new automobiles sales. Accordingly, most profit comes from maintaining and repairing automobiles for automobiles distributors. The most importance for automobiles distributors is to think how to enhance their ability to compete with others. In order to raise the customer satisfaction, the Toyota distributor system introduced Toyota Production System (TPS) since 2003 to increase the production efficiency and shorten the repairing time. This research studies the process of introducing TPS to Toyota distributor system, and then induces why the introducing TPS is successful. In addition, the result is useful when instructing TPS to other industries. This study finds that continuous production line is a key factor to improve the production efficiency. The continuous production line processes one product at the same time to eliminate lead time. To ensure the continuous production line work well, it need to standardize the production process, and divide the process into several work station appropriately according to make each process time equal in each work station. However, for service industry, the amount of customer isn’t the same every day. Whether there are enough customers for the continuous production line to produce economically is also important. Finally, it still needs to combine other policies to ensure the continuous production system work smoothly when introduce TPS to different industries.

Full textAbstract:
The increased globalisation of the automotive industry of South Africa has brought
with it both opportunities and threats for the various players. Companies taking
advantage of the government's Motor Industry Development Plan have quickly
learned that exporting both components and vehicles is the most suitable way forward.
Toyota SA, in its new role as a global player has strategized that sourcing parts from
local suppliers will give it the competitive advantage to then compete internationally.
The company has planned to increase its local content targets from 40% to around
70% in the next few years.
The question that rises to the fore is "are the local suppliers able to cope in meeting
this challenge?" This study explores the various issues faced by Toyota SA as well as
its local suppliers in attempting to achieve these targets. While Toyota SA has to
deliver the expectations of developed countries, it is faced by a local supplier base that
for many reasons, lags behind the rest of the world. The study adopts classical
techniques for analysis as well as recent techniques in evaluating the suitability of the
increased localisation strategy. Finally, based on the impact of the various forces,
recommendations are made as to the strong and weak points of the strategy.
Poor product development capabilities and technical/operational improvement
requirements at suppliers, the lack of internal resources at Toyota SA and finally the
weak second and lower tier supplier levels all emerge as issues to be addressed. These
issues cannot be ignored for the implementation of the increased localisation strategy
to be successful.Thesis (MBA)-University of Natal, Durban, 2003.

Toyota Production System (TPS) has been implementing by Toyota company over 50 years, in the environment of repidly changing market, the TPS still created strong competitive advantage in the industrial sections, and encouraged a lot of enterprises to implement TPS, but there were a lot of cases fail to implement TPS. This research purpose is to investigate the relationship between TPS, HRM, and TQM. Based on this relationship, the integrated model of TPS will be developed and divides into human dimension, technical dimension and performance dimension. A questionnaire was used to collect the data and sent to TPS’ experts. The experts determine the most important items from the questionnaire. After receiving the questionnaire back from the experts, the data will be analyzed using Delphi Method to determine the important items and eliminate the less important one based on mean value. These important items will be compared using AHP technique to calculate the weight value of each important item. The AHP technique also used to build the TPS model, which consists of 41 items. The results of this research can give useful suggestions to the industries who want to implement TPS, and different spoint of view to implemente integrate TPS model, creating a higher competitiveness of enterprises.

Tool machine is always the basis of manufacturing industry， especially the precision manufacturing industry. However， due to the influence of financial recession and the competition from China， Taiwan export has decreased and become less competitive. Therefore， every manufacturer in Taiwan is devoted to the improvement of cost control and the production management to incerease competitiveness. The advantage of Toyota productions systen is that they can raise their quality while reducing costs. To survive in this competitive and low-profit tool machine market， the two most important controllable factors are how to enhance quality and to reduce costs. This study， as the reference for Taiwan tool machine industry， intends to find out the cost-control results of TPS system in S company. The study adapts quantitative analysis and semi-structured interviews with the staffs and managers in S company. The study wants to know how the TPS improves the equipment usage rate， production cost， inventory cost， and labor production. This research is to find out the practical effects of TPS induction process and hopefully it can be the reference for tool machine industry in the future.
