Denna rapport utreder möjligheterna till att reducera ledtiden, med en uppskattning av minst 10%, för plockprocessen på den utlevererande avdelningen som kallas den ”avgående avdelningen” hos EJOT Sverige AB i Örebro. Företaget vill i dagsläget skapa sig en tydlig helhetsbild av processen samt få underlag, för eventuell framtida implementering, i form av förbättringsförslag för en ledtidsreducering. Under arbetets gång beskrivs nuläget utifrån datainsamling, intervjuer och observationer, i kombination med ett spagettidiagram som presenteras. De möjliga rotorsakerna till problemen kartläggs genom att skapa ett fiskbensdiagram som sedan analyseras. Analyserna visar på att processen är komplex och därmed även problemen. Orsaker som valts för vidare analys är: layout, körslinga och placering av låga gods.  Tre förbättringsförslag har tagits fram utifrån analyserna och dessa handlar om att skapa en ny optimerad layout, en ny optimerad körslinga samt att eliminera placeringen av låga gods.  Det fortsatta arbetet bör vara att optimera en ny lagerlayout samt se över och standardisera en ny körslinga. Företaget bör också se över möjligheterna att eliminera placeringen av gods på markplan. / This report investigates the possibilities of reducing the lead time, with an estimate of at least 10%, for the picking process at the delivery unit called the “outgoing department” at EJOT Sverige AB in Örebro. The company currently wants to create an overall picture of the process and get a basis, for possible future implementation, in the form of improvement proposals for a lead time reduction. During the work, the current situation is described based on data collection, interviews and observations, in combination with a spaghetti diagram that is presented. The possible root causes of the problems are mapped by creating an Ishikawa diagram which is then analyzed. The analyses show that the process is complex and thus also the problems. Reasons chosen for further analysis are: layout, driving loop and placement of low goods. Three improvement proposals have been developed based on the analyses and these are about creating a new optimized layout, a new optimized driving loop and eliminating the placement of low goods. The continued work should be to optimize a new warehouse layout and review and standardize a new driving loop. The company should also review the possibilities of eliminating the placement of goods on the ground floor.

Aspects related to communication, unnecessary movement of professionals, patients, materials and information, useless protocols although well written are increasingly observed in health services. For improvements related to handling flow and continuous elimination of waste and activities that do not add value in the hospital, this study aimed to assess the implementation of spaghetti diagram tool in an emergency room of a small hospital in the state of São Paulo. The healthcare lean methodology and spaghetti diagram tool was used. It was identified the current situation and opportunities for improvement, relating to proposition good spaghetti diagram practices in hospitals. The main movement of wastes were mentioned and it was noted that the application of the tool was successful. The importance of the method for reducing the waste stream related to movement flow in a hospital environment has been proved. It is expected that the flow of tasks become efficient, always seeking less time to perform activities using less effort, less cost and reducing the waiting time of the patients in the unit by reorganizing the movement flow in the workplace. / A cada dia percebem-se constantes desperdícios e atividades que não agregam valor algum nos hospitais. Aspectos relacionados à comunicação, movimentação desnecessária de profissionais, pacientes, materiais e informações, protocolos inúteis, apesar de bem escritos, são cada vez mais observados nos serviços de saúde. Visando melhorias relacionadas ao fluxo de movimentação e a eliminação contínua de desperdícios e atividades que não acrescentam valor no ambiente hospitalar, esta pesquisa teve como objetivo a avaliação da aplicação da ferramenta diagrama de espaguete em uma unidade de emergência de um hospital de pequeno porte do interior do estado de São Paulo. Foi utilizada a metodologia lean healthcare e a ferramenta diagrama de espaguete. Identificou-se a situação atual e as oportunidades de melhorias, relacionando-se a proposição de boas práticas de diagrama de espaguete em ambiente hospitalar. Foram apontados os principais desperdícios de movimentação encontrados e percebeu-se que a aplicação da ferramenta pôde ser realizada com êxito. Comprovou-se a importância do método para a redução dos desperdícios relacionados ao fluxo de movimentação em ambiente hospitalar. Espera-se que o fluxo de tarefas torne-se eficiente, buscando sempre menor tempo para realização das atividades, utilizando menos esforços, com menor custo e diminuindo o tempo de espera do paciente na unidade por meio da reorganização dos fluxos de movimentação do ambiente de trabalho.

The work is focused on improving the concept of lean management in a selected engineering company, where analyzes are performed with the help of selected methods and tools to reveal current problems. The data are then processed and based on them, measures for change are proposed with an emphasis on minimizing the rate of waste of time and costs and increasing production efficiency.

Stoneridge, Inc. is an independent designer and manufacturer of highly engineered electrical and electronic components, modules and systems principally for the automotive, commercial vehicle, motorcycle, agricultural and off-highway vehicle markets. A subsidiary of Stoneridge, Inc. is the company Stoneridge Electronics. They specialise in instrument clusters and tachographs which are manufactured in high quantityin their production plant in Örebro, Sweden. This master thesis focuses on the production line of an instrument cluster called Angela. In close collaboration with Stoneridge Electronics, the goal was to find ways to improve the output of the Angela line by at least 10% compared to the three best months in terms of output from the year before. The Angela line was analyzed thoroughly and from different perspectives using lean tools such as value stream mapping, spaghetti diagram and continuous improvement. Finally, the simulation software ExtendSim was used in order to simulate and analyse different suggestions. The results show that various steps can be taken to improve the efficiency and output of the manufacturing line by as much as 16.3%. Due to the fact that other production lines within the production are similar to the one that the project was carried out on, the project results could be applicable for the other lines as well. / Stoneridge, Inc. är en oberoende designer och tillverkare av högteknologiska elektriska och elektroniska komponenter, moduler och system huvudsakligen för fordonsmarknaderna. Ett dotterbolag till Stoneridge, Inc. är företaget Stoneridge Electronics. De är specialiserade på instrument kluster och färdskrivare som tillverkas i produktionsanläggning i Örebro. Denna examensarbete fokuserar på produktionslinje av ett instrumentkluster som heter Angela. I nära samarbete med Stoneridge Electronics,målet var att hitta sätt att förbättra produktionen av Angela linje med minst 10 % jämförtmed de tre bästa månaderna när det gäller produktion från året innan. Angela-linjen analyserades grundligt och från olika perspektiv med lean verktyg som värdeflödesanalys, spaghetti diagram och kontinuerlig förbättring. Slutligen användes simuleringsprogrammet ExtendSim för att simulera och analysera olika förslag. Resultaten visar att olika steg kan vidtas för att förbättra effektiviteten och produktionen av produktionslinjen med så mycket som 16.3%. På grund av att andra produktionslinjer inom produktionen liknar den som projektet genomfördes på, kan projektresultaten vara tillämpliga för andra linjer också.
