Full textA fierce competition among production companies in a global market force them to beefficient in their processes in order to survive. Small companies, lacking the financialstrength of a large company, are even more dependent on an efficient usage of existingresources, since they often do not have the same chance to invest in new equipment. Overall Equipment Effectiveness (OEE) is a ratio that measures a company's equipmentefficiency. Using OEE will help a company trace losses in their production processes inorder to be able to eliminate these.This report intends to clarify to what extent small manufacturing companies in Swedenuse OEE today. The theory suggests that large efficiency improvements are possiblethrough the use of OEE in large companies, however, a limited amount of literaturedescribe the use of OEE in smaller companies. The purpose of this report is toinvestigate what potential there is for small companies to use OEE successfully and toidentify the specific factors for success. In order to fulfil the purpose of the report, interviews have been made with consultantsand small manufacturing companies, all very familiar with OEE. The empirical studywas carried out based on theory, primarily focusing on the usage of OEE in largecompanies. Moreover a questionnaire was sent to small manufacturing companies inorder to obtain a broader view and a deeper understanding of attitudes towards OEE insmall companies in Sweden.The study reveals that there are few small manufacturing companies that use OEE todayin Sweden. One reason is a lack of knowledge among these companies. Another keyissue among small companies is that they are not able to spare staff to work with OEE, since many of them are busy with daily operations. Yet another reason why many smallcompanies do not use OEE – or not even measure their production processes at all – is that they consider their machine utilization as being good already. The results of ourstudy however show that companies often overestimate their own capabilities in thisregard. By starting to measure the production processes, one will often discover flawsthat were previously not understood.Moreover, the study has shown that small companies could use OEE more than they dotoday, in order to maximise their existing machinery’s efficiency. To avoid the specificproblem with limited resources related to small companies, a key factor of success is acareful and continuous implementation in small steps in the company. This is importantregarding the amount of machines you initially decide to measure OEE on, but theimplementation in small steps is also important with respect to what measuring methodsyou use. Initially a small company only needs simple, manual methods. Thesemeasuring methods could later on gradually change to automatic data collectionmethods, when the necessary resources exist within the company. Another key factor ofsuccess is a large management commitment and good communication with theemployees regarding the use of OEE. Small companies have an advantage here, compared to large companies, since the organizational structure is less hierarchical.Overall the understanding of OEE and its long-term positive impact on the company isyet another crucial factor for success.

Full textProcess industries have to strive to attain high resource utilization so as to increase their productivity and competitiveness in the market. Many indicators have been used to measure their manufacturing performance, one of them is the Overall Equipment Effectiveness (OEE). However, high OEE values per se do not ensure superior global performance. Some authors suggest that the consideration of indicators with broader magnitude such as Overall Plant Effectiveness (OPE) is more appropriate to measure and analyze the overall manufacturing performance since it also reflects the impacts of support areas on a plant\'s capacity utilization. This research reviews the application of OEE in companies that depend heavily on the ability to rationalize the utilization of their production capacity and explores the use of indicators derived from it. With this purpose, a literature review is presented to identify the limitations of OEE, to enumerate indicators derived from OEE and characterize them as management tools that may offer a more global perspective to the measurement of capacity utilization. Moreover, a case study is developed in a food processing company to identify how the diverse agents responsible for the losses in production capacity including those who perform beyond the manufacturing function, can be involved in the effort to eliminate or control this problem. The study shows that the use of OPE besides OEE can make the detection of the root cause of problems more effective and induce the integration of manufacturing strategy with other functional strategies, and thus promote the increase of overall manufacturing performance.

Os níveis de eficiência com os quais as empresas transformam os insumos em produtos podem conduzir as organizações para o aumento da sua capacidade competitiva. No entanto, a literatura apresenta uma escassez de métodos que possibilitem a avaliação de desempenho das operações nos sistemas produtivos, considerando todos os seus componentes. Assim, o objetivo deste trabalho é propor uma análise de eficiência em um sistema produtivo utilizando o OEE e a DEA integradamente. Para atingir o objetivo proposto é realizado um estudo de caso em uma empresa fabricante de ônibus. Foi conduzida uma análise comparativa com os resultados obtidos por meio da utilização da DEA/OEE confrontados com os resultados do OEE medido em uma operação da empresa estudada. A eficiência medida com o uso da DEA/OEE apresenta diferenças em relação aos resultados do OEE. A análise das causas dessas diferenças apontou que as ações tomadas para melhorar o indicador OEE reduziram a eficiência da operação analisada. O estudo aponta que as tomadas de decisão focadas na melhoria do OEE, em si, podem conduzir a um incremento do consumo de recursos em uma operação. Esse aumento de recursos não necessariamente eleva os níveis de produção, ocasionando, assim, a redução da eficiência técnica.
The levels of efficiency with which firms turn inputs into products can lead organizations to increase their competitive capacity. Nevertheless, the literature presents a shortage of methods that allow the evaluation of the performance of the operations in the productive systems, considering all its components. Thus, the objective of this work is to propose an analysis of efficiency in a productive system using the OEE and the DEA integrated. To achieve the proposed goal a case study is carried out at a bus manufacturer. A comparative analysis was conducted with the results obtained through the use of DEA/OEE and the results of OEE measured in an operation of the company studied. The efficiency measured with the use of DEA/OEE presents differences in relation to OEE results. The analysis of the causes of these differences pointed out that the actions taken to improve the OEE indicator reduced the efficiency of the analyzed operation. The study points out that decision-making focused on improving OEE itself may lead to an increase in resource consumption in an operation. This increase in resources does not necessarily raise production levels, thus reducing technical efficiency.

Full textSiemens Industrial Turbomachinery AB (SIT AB) i Finspång är ett företag vars verksamhet är inriktad på tillverkning av gas- och ångturbiner för främst industriella tillämpningsområden. Företaget har cirka 2 100 anställda och är en del av den tyska storkoncernen Siemens AG. Inom SIT AB har det sedan tidigare funnits en delad mening kring vilka orsaker som främst bidrar till förluster inom företagets produktion. I dagsläget genomförs flera olika typer av driftsuppföljningar, ett problem är dock att dessa inte är synkroniserade för att ge en tydlig förlustbild på maskinspecifik nivå. Till följd av detta önskar nu produktionsansvariga på SIT AB undersöka möjligheten att mäta utrustningseffektiviteten hos sina maskinresurser genom införande av mätetalet Overall Equipment Effectiveness (OEE). Genom ett pilotprojekt ska en metod för mätning av OEE på SIT AB utvecklas, denna ska sedan implementeras och testas på två av företagets fleroperationsmaskiner. Pilotprojektet genomförs i form av ett examensarbete, arbetet ska ligga till grund för rekommendationer gällande hur mätresultaten ska användas samt hur SIT AB ska gå tillväga för att kunna genomföra OEE-mätningar i större skala.
OEE avser mätning av total utrustningseffektivitet genom ett enda mätetal. Syftet med beräkningen är att åskådliggöra omfattningen av de sex stora produktionsförluster som definieras inom ramen för Total Productive Maintenance. Efter förlustanalys kan välriktade förbättringsåtgärder vidtas med avsikt att öka utrustningseffektiviteten hos den studerade resursen.
Inom denna undersökning konstateras att OEE är ett mätetal som främst är framtaget för applikation i processliknande industrier. Eftersom SIT AB bedriver tillverkning i en huvudsakligen funktionell verkstadsmiljö krävs viss anpassning för att öka mätetalets tillämpbarhet på företaget. En sådan anpassning får även stöd i litteraturen där det klargörs att det är viktigare att åstadkomma en mätning som kan ligga till grund för förbättringsarbete än att strikt följa grunddefinitionen av OEE. Som stöd för metodanpassningen genomfördes en fallstudie på Kongsberg Terotech AS (KTT), ett av nordens ledande företag inom branschen för underhåll av verktygsmaskiner. KTT har stor erfarenhet inom OEE-mätning genom arbete som rådgivare på uppskattningsvis 15-20 olika företag där verksamhetsområdena sträcker sig från enstyckstillverkning till processindustri och från skärande bearbetning till livsmedelindustri.
Den metod som utvecklats för mätning av OEE på SIT AB är helt baserad på storheten tid. Mätningen sker genom tidsregistrering inom ett diskret antal fördefinierade förlustkategorier, framtagna specifikt för de studerade maskinerna. Genom utvecklandet av en specialdesignad blankett kan datainsamlingen skötas av maskinernas operatörer under pågående ordinarie arbete. Mätningarnas manuella utförande utgör ett hinder för exakt stopptidsmätning, konceptet kan dock införas med kort varsel och utan krav på dyra investeringar i avancerad mätutrustning.
På inrådan från KTT genomfördes OEE-mätning under en period om fyra veckor i respektive maskin. Förlustdata kunde insamlas från 95 av 96 möjliga skift och dataunderlaget omfattar 564 respektive 576 planerade produktionstimmar i vardera resurs. Trots att de båda fleroperationsmaskinerna i princip är identiska till utförandet uppvisades förlustbilder som i jämförelse är relativt olika. Av detta dras slutsatsen att maskinerna bör behandlas individuellt vid vidtagandet av eventuella förbättringsåtgärder.
OEE-mätning är något som enbart ska utföras i syfte att underlätta och motivera kontinuerligt förbättringsarbete kopplat till företagets tillverkningsprocesser. Den framtagna mätmetoden kan hjälpa SIT AB att värdera förbättringspotentialen hos den studerade produktionsutrustningen, insamlad data kan även användas för att prioritera hur förbättringsinsatserna ska fokuseras. Huvuddragen i metoden kan även användas för mätning i stor skala, förlustkategorier bör dock väljas utgående från den maskin där mätningarna ska introduceras. En tydlig nackdel är att metoden i nuvarande utförande inte säkerställer god kvalitet i insamlad data, detta kan innebära viss risk för att beslut fattas på felaktiga grunder. Metoden kan vara lämplig att använda som introduktion till OEE-mätning eller i det fall att företaget vill undvika mer omfattande investeringar kopplat till mätningarna. Om SIT AB i framtiden vill satsa på OEE-mätning rekommenderas att datainsamlingen automatiseras.
Det förbättringsarbete som ska följa av genomförda OEE-mätningar bör skötas av förbättringsgrupper tillsatta för ändamålet. Förbättringsgrupperna innehåller med fördel personal med olika kunskapsområden. En tvärfunktionell sammansättning bör innebära att förbättringsarbetet kan skötas på ett mer mångsidigt sätt än vid behandling av enskilda personalgrupper. Den viktigaste förutsättningen för ett lyckat förbättringsarbete är att alla beslut kan baseras på fakta från verkligheten, mätningar som exempelvis OEE utgör konkreta verktyg för att åstadkomma denna situation. För att kunna styra och förbättra centrala produktionsprocesser måste dessa ständigt utvärderas. I detta sammanhang kan införandet av OEE-mätning komma att spela en central roll för verksamheten på SIT AB.
Siemens Industrial Turbomachinery AB (SIT AB) in Finspong is a company dedicated to the production of gas- and steam turbines mainly for industrial applications. The company has around 2 100 employees and is a part of Siemens AG based in Germany. There have previously been different opinions regarding what the largest causes of losses within the company’s production are. Today a number of different ways to follow up on the production is used, a problem with these are however that they are not synchronized to give a clear view of the losses on any specific machine. As a result the production managers at SIT AB now want to look into the possibility of measuring the machines´ effectiveness by introduction of the technique Overall Equipment Effectiveness (OEE). A method for measuring OEE at SIT AB will be developed through a pilot study, this will then be implemented and tested on two of the company’s multifunctional machines. The pilot study is to be performed in the form of a master’s thesis, the paper will be the basis for recommendations regarding how the results of the measurements shall be used and how SIT AB should go about making the measurements usable on a grander scale.
OEE is used to show a resource’s total effectiveness with a single parameter. The calculations are aimed at illustrating to which extent the six big losses defined within Total Productive Maintenance affect the production. After the losses have been analysed improvement measures can be taken in order to increase the previously measured resource effectiveness.
Within this thesis it is concluded that OEE is developed mainly for use in mass-producing industries. Since SIT AB conducts production with similarities closer to a work-shop some adjustments have to be made in order to make OEE more applicable in the company. Such adjustments are supported by the literature where it is stated that it is more important to achieve a measurement which can be used as a basis for improvement rather then to strictly follow the original definition of OEE. As a support for the work with these adjustments a case study was conducted at Kongsberg Terotech AS (KTT), one of the leading companies regarding maintenance of tooling machines in the Nordic countries. KTT has gained a lot of experience when it comes to measuring OEE since they have worked as counsellors at approximately 15-20 different companies ranging from production of single units to mass-production and from metalwork to the food industry.
The method developed for the measurement of OEE at SIT AB is completely based on the entity time. The information is gathered by means of time being registered within a discrete number of predefined loss-categories designed specifically for the studied resources. Since a specially designed form is used the gathering of information can be performed by the operators during regular work. Exact registration of losses is hindered by the measurements being performed manually, however this allows the concept to be introduced with short notice and without the need of expensive investments regarding advanced equipment.
For manual data collecting KTT advised that the measurements should be performed for a period of four weeks in each machine. Data containing the losses could be gathered from 95 out of 96 shifts, which means observation of 564 and 576 planned production hours respectively in each machine. Despite the identical features of the multifunctional machines they presented different losses. This leads to the conclusion being drawn that all machines must be treated individually when it comes to deciding improvement measures.
Measuring OEE should only be carried out when the purpose is to create a basis for continuous improvement of the company’s production processes. The developed measuring technique can aid SIT AB in evaluating the potential for improvement of the studied equipment, the data can also be used to prioritize where improvement measures should be taken first. The main part of the technique can be used for measurements on a grander scale, the loss categories should however be chosen in accordance with the specific machine being studied. A clear down side is that the method in its current state does not secure good quality data, this can potentially mean that decisions are made based on false information. The method is suited for an introduction to OEE or if a company wants to avoid extensive investments. For the best possible result an automatic data collecting system is advised.
Improvement activities based on the OEE measurements should be carried out in groups appointed for the task. These groups should consist of staff with different areas of expertise, a cross functional composition will hopefully mean that the work with improvements can be undertaken in a versatile manner. The most important prerequisite for successful work with improvements is that all decisions are based on facts, measuring OEE can be used as a tool to present the reality. In order to be able to control and improve important production processes these must be constantly evaluated. In this context the introduction of OEE measurements can play an important role for the production system at SIT AB.

Full textHård konkurrens mellan industriföretag tvingar dem till att ständigt arbete med att förbättra sina prestationer. Utvecklingen av "Lean Manufacturing" program för att uppfylla detta syfte bidrar till populariteten av Overall Equipment Effectiveness (OEE); ett mätverktyg som används för att bedöma produktiviteten hos en utrustning beroende på dess tillgänglighet, prestanda och kvalitet.OEE filosofin har anpassats för att uppfylla krav hos företag där processer är automatiserade och företag där processer är manuell. Men implementeringen av detta koncept i ett företag med halvautomatiserade processer (dvs. processer som kräver både manuella ingrepp och automatiserade åtgärder) är fortfarande en utmaning. Denna avhandling avser att utforma och implementera en prestanda indikator, inspirerad av OEE filosofi, på halvautomatiska produktionslinjer.För att nå detta mål, har denna avhandling utförts i ett företag som utvecklar och tillverkar flygplans navigationsinstrument. Tillverkningen av dessa produkter realiseras på halvautomatiska produktionslinjer, som kräver både ingripande av kvalificerade operatörer och pålitliga maskiner . Undersökningar har utförts i samarbete med företags managers för att får förståelse för specifikationerna för halvautomatiska miljöer. För att utforma en prestanda indikator relevant för dessa analyser har arbetsgrupper bestående av ingenjörer i bolaget bildats. Diskussioner med operatörerna har sedan gjorts för att implementera denna indikator på företagets produktionslinjer. Samtidigt utvecklade författaren till denna uppsats ett verktyg för att visualisera information om den uppmätta prestandan på dessa linor.Diskussionerna som utförts inom arbetsgrupperna resulterar i definitionen av prestanda som andelen produkter som inte påverkas av tidsförluster. Insamlingen av dessa tidsförluster säkerställs genom införandet av en tabell på produktionslinorna som gör det möjligt för operatörerna att rapportera problem de stöter på. Denna metod understryker att engagemang från alla medarbetare, från högsta ledningen ner till arbetarna på verkstadsgolvet, är en viktig framgångsfaktor för implementeringen av prestanda indikator.Dessutom visar studierna som utförts av författaren till denna uppsats att den övergripande prestandan hos halvautomatiska produktionslinjer påverkas av organisationen, produktions medel samt produktens prestanda. Dessa analyser påvisar att uttrycka den övergripande prestandan som den genomsnittliga prestandan av de tre entiteter som nämns ovan återspeglar den faktiska produktiviteten hos halvautomatiska produktionslinjer. Klassificeringen av tidsförlusterna med avseende på den entitet som de tillhör gör det möjligt att detektera den begränsande faktorn för den övergripande prestandan. Utöver detta så förser Pareto diagrammen, som visas i verktyget som utvecklats av författaren, en visuell identifiering av de områden där förbättringsåtgärder måste sättas in först.

Full textExamensarbetet är utfört vid Pågens bageri i Göteborg, vid bageriet tillverkas både matbröd och kaffebröd. Bageriet har totalt elva produktionslinjer med varierande produkter och antalsorter per linje. Detta projektet är utfört vid en av de linjer som producerar flera olika sorters bröd, där fokus legat på de tre produkter som står för majoriteten av produktionen. Uppgiften bestod i att kartlägga och analysera linje 39 utifrån problemområden som påverkar utnyttjandegraden(OEE%) negativt.Linje 39 har idag en genomsnittlig OEE% på 61,9% jämfört med det uppsatta målet på 85%. Kartläggning och analys av nuläget skedde genom intervjuer, observationer, arbetsmätningar, sammanställning av data och värdeflödesanalys. Målet med projektet är att identifiera problemområden för linje 39 ́s process som påverkar OEE% negativt och om möjligt komma med lösningsförslag utifrån relevant litteratur, samt att standardisera omställningar vid paketeringen genom SMED-analys. Utifrån nulägesbeskrivningen samt värdeflödesanalysen kunde följande problemområden identifieras: Avsaknad av standardiserade arbetsmetoder vid omställningar vilket kan leda till flera typer av slöserier. Stor procentuell del av kapacitetsförluster som hör till övriga utnyttjandeförluster vilken inte går att härleda till specifikorsak eller problemområde. Felaktigdata vid beräkning av teoretisk kapacitet Upplevd stress hos operatörer i samband med omställningar Utifrån de identifierade problemområden togs lösningsförslag fram för problemområdena med hjälp av relevant litteratur för att skapa en effektivare process och utnyttjandegrad. Detta skedde genom utförande av Single Minute Exchange of Dieför omställningar i paketeringen samt analys av liggtider vid sortbyten i degavsnittet Genom användandet av litteratur och Single Minute Exchange of Die kunde en standard för omställningar mellan produktsorter tas fram för paketeringen, vilken kan minska omställningstiden med upp till8,5minuterfrån 23,5 till 15 minuter. Detta resultat ger idagingen förändring av OEE% då de varierande ställtiderna härstammar från degavsnittet tidigare i flödet.Utifrån analysen av liggtider mellan olika produktsorter kunde en standard tas fram om när degen för nästa produktsort bör påbörjas för att skapa en produktionslucka på 30 min som idag är standard. Vid införande avstandardiserade arbetsmetoderoch införande av korrekta data i kalkylbladen kan linje39’s OEE% förbättras från 61,9% till 71,2%. Genom införande av standardiserade arbetsmetoder kan även operatörernas upplevda stress minskas genom att de vet vad som förväntasav dem under omställningarna. Ett stort problemområde som kvarstår är posten för övriga utnyttjandeförlustersom Pågen behöver arbeta vidare med att kartläggadessuppkomst för att kunna eliminera förlusterna.

Full textPurpose: 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.

Full textDet finns stora förluster i sågverk som inte framkommer av deras traditionella driftsuppföljnings¬processer. Strategiskt viktigt för organisationen är frågan vad företaget behöver göra för att bli effektivt. I detta arbete diskuteras mätmetoder av effektivitet med avseende på underhåll och hur effektiviteten kan mätas med hjälp av att beräkna den totala utrustningseffektiviteten (OEE). Arbetet beskriver också olika underhållsstrategier och processen med att införa en sådan policy på sågverk. Under en period av sex dagar beräknas OEE på fem sågverk. Resultatet var att OEE värdet i snitt var runt 50 procent, som är ganska lågt. Genom att applicera en kostnadseffektiv underhållspolicy kan företaget öka sitt OEE värde och få en mer effektiv process. Detta kan göras genom att en policyn minskar de övergripande kostnaderna relaterade till de sex stora förlusterna. Diskussion förs också kring avvikelserna/stoppen och hur orsakerna till dessa kan härledas genom analyser med t.ex. Ishikawadiagram. Arbetet lyfter fram att ett systematiskt förbättringsarbete skulle ge nästan ett fördubblat kapacitetsutnyttjande för sågverken utan några större investeringar. I arbetet beskrivs hur sågverken kan bli framgångsrikare med detta genom att välja en kostnadseffektiv underhållspolicy.
There are several big losses in sawmills that are not addressed by the traditional operation feedback systems. It is strategic significant for organizations to address the question what need to be done in order to bee more effective. This work discusses methods of measurement the effectiveness with respect to maintenance and how the effectiveness can be measured by assessing the Overall Equipment Effectiveness (OEE). The work also emphasizes on maintenance strategies and the process of implementing such a policy in sawing mills. During a period of six days assessments of OEE were made in five different sawmills. The results were that OEE in general were about 50 percent, which is considered low. By implementing a cost-effective maintenance policy, it will lead to increase the value of OEE for the process. Using a policy that will decrease the overall costs related to the six big looses could do these. Discussions the production stoppages and how these can be analyzed by using different tools, such as Ishikawa diagram are addressed. The work highlights that a systematic improvement work would increase appreciably the capacity utilized without any large investments. This study also describes how sawmills can be successful when increasing their effectiveness by selecting a cost-effective maintenance policy for their process.

Características existentes no processo de produção da indústria de fluxo contínuo, particularmente a petroquímica, requerem que a medição de eficiência inclua características diferentes da indústria de produção intermitente, tais como a maneira de quantificação dos produtos finais e a natureza das perdas que são consideradas no cálculo da eficiência de produção. Indicadores de eficiência global de produção tipicamente são derivados do OEE (Overall Effective Equipment), proposto por Nakajima (1988) para a indústria de produção intermitente e, por vezes, são utilizados em indústrias de produção contínua sem uma análise prévia de suas limitações. Doze indicadores identificados na literatura foram analisados e comparados com características do processo de produção da indústria petroquímica, obtidos a partir da revisão teórica e de entrevistas com profissionais e pesquisadores dessa indústria. Dessa análise identificou-se que o indicador OAE (Overall Asset Efficiency) apresenta maior aderência em relação à classificação de perdas e às características do processo de manufatura da indústria petroquímica. Os resultados de eficiência global de produção obtidos através da utilização do OAE foram confrontados com os provenientes do OEE e do TEEP (Total Effective Equipment Productivity), com base em dados reais de uma empresa localizada no Pólo Petroquímico do Rio Grande do Sul. Os resultados obtidos através do cálculo de eficiência utilizando o indicador selecionado OAE, se mostraram mais descritivos da realidade da empresa quando comparados com aqueles atualmente utilizados. Outras práticas que geram interferências sobre o cálculo do OEE também foram identificadas nas entrevistas. Ainda, foi identificada a necessidade de uma discussão mais ampla no sentido de melhor definir os conceitos de capacidade e nível de atividade na indústria petroquímica e sua estimação operacional para fins de análise de eficiência, bem como, a incorporação de termos relativos à eficiência de insumos e custeio na análise de eficiência operacional global dessa indústria.
Due to singular characteristics present in the production of continuous flow process industry, especially petrochemical, efficiency measurement require different features of intermittently producing industry, such as how to quantify the final products and the cause of the losses that are considered in the calculation of production efficiency. Production efficiency indicators are typically derived from the OEE (Overall Equipment Effective) proposed by Nakajima (1988) for intermittent production industry, they are sometimes used in continuous manufacturing industries without a prior analysis of their limitations. Twelve indicators identified in the literature were analyzed and compared with features of the petrochemical industry production process, obtained from theoretical review and interviews with professionals and researchers in this industry. This analysis identified that the indicator OAE (Overall Asset Efficiency) has a better production losses structure and fits the characteristics of petrochemical manufacturing process. The results of overall production efficiency obtained using the OAE were compared with results from OEE and TEEP (Total Effective Equipment Productivity), based on manufacturing data from a company located in Rio Grande do Sul petrochemical complex. The results obtained from the efficiency calculation utilizing the selected indicator OAE, are more descriptive of the company situation when compared to those currently used. Other practices that causes interference on the calculation of OEE were also identified in the interviews. It was also identified the necessity for a broader discussion in order to better define the concepts of capacity and activity level in the petrochemical industry and also the operational way define them in order to make analysis of efficiency as well as the incorporation of terms concerning the efficiency of inputs and costing the analysis of overall operational efficiency of this industry.

Full textA Eficácia Global dos Equipamentos ou Overall Equipment Effectiveness (OEE) é uma métrica Lean que surgiu na metodologia TPM (Total Productive Maintenance), a qual permite às empresas analisar a sua real situação através da identificação de todas as perdas relacionadas com os equipamentos e da avaliação da capacidade de produção dos mesmos. Todas as perdas identificadas nos equipamentos estão relacionadas com um dos três fatores que constituem o OEE: disponibilidade, eficiência e qualidade. O presente projeto descreve a aplicação do indicador OEE numa das etapas do processo produtivo de uma unidade industrial da Amorim & Irmãos, S.A. de forma a melhorar a eficácia global dos equipamentos e a sua produtividade. Após a análise dos valores obtidos para o indicador OEE, assim como para os seus fatores, concluiu-se que o fator mais crítico era a eficiência. Como este fator é influenciado pela ocorrência de micro paragens é sobre este tipo de perdas que o restante projeto se debruça. Existem duas formas de melhorar a eficiência: diminuir a ocorrência das causas das micro paragens e/ou diminuir o tempo improdutivo associado a cada micro paragem. Através do diagrama de causa-e-efeito identificaram-se todas as causas que originavam a ocorrência de micro paragens e com a aplicação do diagrama de Pareto identificaram-se as causas mais significativas para o tempo improdutivo devido à ocorrência de micro paragens. Para reduzir a ocorrência das micro paragens mais significativas realizaram-se alterações técnicas nos equipamentos e, posteriormente, foram realizadas redistribuições das tarefas pelos operadores dessa etapa do processo, com o intuito de diminuir o mais possível o tempo de espera das máquinas quando ocorre uma micro paragem e, consequentemente, o tempo improdutivo associado às mesmas. Os resultados obtidos com a aplicação da métrica OEE evidenciam a potencialidade e o elevado impacto que esta promove em ambientes produtivos.
The Overall Equipment Effectiveness (OEE) is a Lean metric that appeared in TPM (Total Productive Maintenance), which enables companies to analyze their actual situation by evaluating the equipment production capacity and identifying all losses related with them. All losses identified in equipment are related to one of three OEE factors: availability, efficiency and quality. This project describes the application of OEE indicator in one of the stages of the production process of an industrial unit in Amorim & Irmãos, S.A., in order to improve the overall effectiveness of equipment and their productivity. After analyzing the values obtained for the OEE indicator, as well as their factors, it was concluded that the most critical factor was the efficiency. Since this factor is influenced by the occurrence of micro stops, the remaining project focuses about this kind of losses. There are two ways to improve efficiency: reducing the incidence of the causes of micro stops and/or decrease the downtime associated with each micro stop. Through the cause-and-effect diagram it was possible to identify all the causes that originated the occurrence of micro stops, and with the application of Pareto diagram the most significant causes of downtime due to the occurrence of micro stops were also identified. To reduce the occurrence of the most significant micro stops there were technical changes in equipment and then were made redistributions of tasks among the operators in this stage of the process, in order to reduce as much as possible the waiting time of the machines when a micro stop occurs, and hence the downtime associated with them. The results obtained with the application of OEE metric showed the potential and the high impact it promotes in production environments.

Full textDetta examensarbete är utfört på Swepart transmission AB i Liatorp. Företaget är ett tillverkande företag av transmissionslösningar. Allt efter som kundkrav och tillverkningsvolymer ökar innebär det att högre krav ställs på produktionen. Syftet med arbetet har därför varit att höja OEE-talet och lönsamheten i en av företagets produktionsceller, med tillhörande svarv. Studien är begränsad till de tre vanligaste artiklarna som går i cell 1: 433, 401 och 296. Frågeställningens syfte är att identifiera kapacitetspotentialen i cellen, men även att analysera vilka åtgärder som kan göras för att höja kapaciteten. För att svara på frågeställningarna har observationer av produktionen gjorts och insamlade data från Axxos har använts. Produktionslayouten har noga studerats för att få reda på vilka faktorer som påverkar utnyttjandegraden i cellen. Med denna data har OEE-talet räknats ut för cellen, både för hela cellen och för de olika artiklarna. Även tidsaxlar över robotens och maskinernas cykeltider i cellen har gjorts för att se vilka tidsförluster som sker i cellen. Resultatet visar att de största kapacitetsförlusterna ligger i anläggningsutnyttjandet för två av artiklarna, där svarven är den styrande faktorn. Tidsaxeln för den sista artikeln visar dock att cykeltiden enkelt kan minskas genom att öka hastigheten för fräsen. Det finns också stora förluster som kan förbättras i tillgängligheten, där personalbrist utgör en stor del av stoppen. En annan viktig del att ta i beaktning är att arbeta med svarven enligt flaskhalsteori. Detta innebär att se till att svarven alltid är tillgänglig för produktion. En viktig men enkel åtgärd är att öka tillverkningstakten för artikeln 433. Detta skulle innebära att den möjliga körtiden för svarven hade ökats, och därmed för hela cellen på grund av att svarven är en flaskhals. En annan viktig åtgärd är att se över sättet de arbetar med deras OEE-tal i Axxos, då de enligt det nuvarande arbetssättet döljer viktiga och stora förluster. Det är också viktigt att se till att stoppen och cykeltider i svarven också registrerar i Axxos. Eftersom svarven är en flaskhals är den det viktigaste att hålla koll på. Arbetet har visat att det finns stor kapacitetspotential i cellen, men att det är till stor del begränsat av svarvens långsamma produktionstakt. Det är därför viktigt att behandla svarven som en flaskhals och att eliminera de faktorer som gör att svarven inte kan producera under planerad produktionstid.

A concorrência no setor farmacêutico é intensa e os produtos farmacêuticos possuem tempo de ciclo reduzido quando comparado com os grandes investimentos de P&D. Para concorrer neste setor, as indústrias estão sempre com foco em melhorar a eficiência dos processos de manufatura utilizando muitas vezes equipamentos complexos, modernos e automatizados com foco na produção para atingir as metas. Neste contexto, o objetivo deste trabalho é demonstrar o melhor controle da produção utilizando como base a metodologia de Manutenção Produtiva Total da Produção buscando a maximização da eficiência dos equipamentos e recursos disponíveis, utilizando várias ferramentas dentre elas a Overall Equipment Effectiveness (OEE) conhecida como eficiência global dos equipamentos de produção. Esta ferramenta permite monitorar o desempenho da linha de produção, identificar os principais gargalos, monitorar os índices de OEE, sugerir ações de melhoria no processo. Na análise de resultados do OEE ficou evidenciado que os setups, troca de máquina, representavam grandes desperdícios ao processo produtivo sendo então utilizado o SMED para redução destes tempos e conversão em tempos reais de produção. Também a utilização e implementação de outras ferramentas de apoio à implementação, manutenção e sustentação da produtividade como: trabalho padrão, análises de causa-raiz, guia de solução de problemas, criação de um conselho de OEE, educação e treinamento, Gemba, Kaizen, 5 s, trabalho padrão para liderança, controles visuais, reuniões de níveis de responsabilidade baseadas no sistema lean de gerenciamento de produção (Tier 1, Tier 2, Tier 3 e Tier 4). O conjunto destes resultados acaba aumentando o lucro, a produtividade e qualidade, reduzindo assim os custos para o setor farmacêutico possibilitando maior competitividade. Neste estudo ficou possível observar que com a implementação destas ferramentas de gerenciamento da produção transformou-se desperdícios envolvidos no processo em tempo real de produção.
The competition in the pharmaceutical industry is intense and the products have reduced life cycles when compared to the large investments in R&D. To compete in this sector is necessary to improve the efficiency of the manufacture processes often using complex, equipment, modern and automated with focus in the production to reach the goals. In this context, the objective of this work is to demonstrate better control of production basis in the use of Total Productive Maintenance seeking to maximize the efficiency of equipments using various tools among them the Overall Equipment Effectiveness. This tooling allows you to improve the acting of the production line, to identify the bottle mouths, monitor OEE index, and suggesting improve actions in the process. Related the results of OEE analysis have been demonstrated that setup represented major wast in the production process so that the tooling SMED was used to reduce the time of change on the machine and convertion on the productive time. Beyond use of OEE another tools are used to support the implementation, maintenance and support the productivity as standard work, root cause analysis, troubleshooting, creating of OEE Council, education & training, gemba, Kaizen, 5 S, leader standard work, visual control, tier accountability based on the Lean Methodology (Tier 1, Tier 2, Tier 3 and Tier 4). The group of these results ends up increasing the profit to the productivity, quality, and cost reduction to the pharmaceutical industry enabling greater competitiveness. In this study was possible to observe the implementation of managament production tooling that’s convert waste time in an production real time.

Full textIn today’s production, effectivity and minimizing the waste are increasing. When starting up a production unit, there is a lot of planning, testing and decisive considerations. When installing and building the line, production balances and stations, different scenarios are needed to be prepared for production start. The model developed during the work will form the basis for improvement work for a more efficient production at Azelio in Uddevalla. This study consists of an analysis of a production engineering project to analyse the influencing factors on the efficiency of the balances. The purpose of the work is to develop a model that allows visualization of the parameters that may interfere with future production flows based on risks and circumstances surrounding the production. With the knowledge previously gathered during the study period, these knowledges could be applied in this work. The work then resulted in a template that could visually show whether the efficiency was around the balances in the production. Initially, a current situation analysis for the production flow was carried out, whether the product is intended to pass through production and what happened at each balance. This enabled a basic understanding of the production and the product. Secondary data was collected in an Excell sheet where the data which the company made estimates and measurements were collected. Later in this way primary data could be obtained and managed. Finally, secondary data was used as the basis for the design of the model that was developed during the work. The model resulted in a visualization of the efficiency of the balances, taking into account six different parameters that may affect the efficiency of the factory in different circumstances. How much the various parameters will affect the final production is difficult to determine at present, but it will be evaluated when production is in progress.

Atualmente, a indústria farmacêutica encontra-se inserida em um cenário de acirrada competição, enfrenta custos crescentes de pesquisa e desenvolvimento e está submetida a maiores exigências regulatórias. Soma-se a este quadro, reduzida eficiência operacional. Neste contexto, torna-se importante que as empresas farmacêuticas busquem mensurar e melhorar o desempenho de suas operações e equipamentos. Mundialmente e em diversos segmentos industriais, o indicador de eficácia global de equipamentos (Overall Equipment Effectiveness, OEE) é adotado como métrica do desempenho de máquinas e linhas produtivas. Através de estudo de caso, aplicado à produção de Farmanguinhos, verificou-se que o emprego da OEE permite identificar e quantificar as perdas que afetam o funcionamento dos recursos produtivos, servindo de base para o desenvolvimento de ações de melhoria contínua. Na implantação do indicador é fundamental assegurar que os operadores responsáveis pela coleta dos dados assimilem os objetivos e conceitos da metodologia e sejam capacitados a classificar corretamente as perdas. A análise dos resultados de OEE evidenciou que os processos de troca de máquina (set ups) representaram os desperdícios de maior impacto sobre a disponibilidade dos equipamentos em estudo. Foi verificado que princípios da troca rápida de ferramentas (Single Minute Exchange of Dies , SMED) podem ser utilizados para redução do tempo destas operações.
Currently, the pharmaceutical industry is inserted in a scenario of fierce competition, facing rising costs of research and development and is subjected to increased regulatory requirements. Reduced operational efficiency is added to this picture. In this context, it is important that pharmaceutical companies strive to measure and improve the performance of its operations and equipments. Worldwide and in several industrial sectors, Overall Equipment Effectiveness (OEE) indicator is adopted as the performance metric of machines and production lines. Through case study, applied to Farmanguinhos production, it was verified that the use of OEE enables identifying and quantifying the losses that affect productive resources operation, providing the basis for the development of continuous improvement actions. In the indicator’s implantation it is fundamental to assure that operators responsible for data collection assimilate the purposes and concepts of the methodology and are able to classify the losses correctly. The analysis of OEE results revealed that set up processes represented the waste of largest impact on the availability of the equipments under study. It was verified that principles of Single Minute Exchange of Dies (SMED) can be used to reduce the time of these operations.

Este trabalho tem como tema a análise da incorporação dos efeitos variabilidade dos processos sobre o indicador IROG (Índice de Rendimento Operacional Global) e os seus desdobramentos na GPT (Gestão do Posto do Trabalho). Como objetivo principal buscou-se a proposição de um modelo para avaliação do impacto da variabilidade sobre o IROG e a GPT. O modelo proposto foi testado em duas empresas do segmento metal-mecânico, a partir do estudo de quatro postos de trabalho. Parte-se, inicialmente de uma revisão bibliográfica dos conceitos da GPT e da evolução do uso do indicador IROG na avaliação da eficiência dos equipamentos vinculada à TPM (Total Productive Maintenance); considera-se ainda, as perdas por gestão tais como: falta de programação, falta de operador, reuniões, etc. Também fizeram parte da revisão bibliográfica os conceitos relacionados à variabilidade dos processos e formas para o seu monitoramento. Com base nos estudos de caso desenvolvidos em quatro equipamentos, comprovou-se que a aplicação do modelo proposto proporcionou melhorias nos resultados do IROG. Como exemplos destes resultados citam-se: o aumento do IROG no mês dezembro de 49% para 62% no caso 1 e de 71% para 77% no caso 3. Outro resultado percebido está relacionado ao uso do modelo como ferramenta de gestão, o que proporcionou aos envolvidos na GPT, um melhor entendimento da variabilidade, a correta identificação das causas comuns e especiais de variação e, conseqüentemente, a tomada de ações apropriadas nos postos de trabalho.
This work has covered the analysis of the incorporation of the effects related to process variability on the OEE (Overall Equipment Effectiveness) Index and its consequences on WM (Workplace Management). The main objective was to propose a model for assessing the impact of variability on OEE and WM. The proposed model was tested in two metal-mechanic companies, by studying four work stations. It originally started with a review of the concepts of WM and the evolution of the use of OEE in evaluating the efficiency of equipment tied to the TPM (Total Productive Maintenance); it has been considered as well management wastes such as lack of production planning, lack of operator, meetings, etc. A review of the concepts related to the variability of processes and ways to monitor it were also taken into consideration. Based on case studies developed in four equipments, it was shown that the implementation of the proposed model provided improvements in the results of OEE. For instance: the OEE increased in last December from 49% to 62% in case 1 and from 71% to 77% in case 3. Another result is related to the perceived use of the model as a management tool, which provided for those involved in the WM a better understanding of variability, the correct identification of common and special causes of variation and, consequently, the implementation of appropriate action on the work stations.
