Optimalizace vnitropodnikové logistiky / In-plant logistics optimalization

Maroušek, Jan January 2008 (has links)
In a theoretical part of this work there is introduced a general view on logistics and its development, than a view on creating value for customer, basics of lean production, lean thinking and following methods as Six Sigma and Value Stream Mapping. At the end of the theoretical part there is mentioned outsourcing of logistics services and view on relationship between logistics provider and a client. In a practical part there is introduced a project of in-plant logistics optimalization in a factory producing steel pannels for MINI Cooper production. At the beginning there is introduced the factory itself, logistics services provider and a background of the project birth. Than there is a step by step description of a work on the project respecting a DMAIC methodology, it means that it's a classical example of a Six Sigma project using a Value stream mapping tool.

Effektivisering av transportprocessen : En fallstudie om lean i ett globalt transportföretag / Streamlining the transport process : A case study about lean in a global transport company

Nyqvist, Nicole, Josefin, Murath January 2017 (has links)
Transporter har blivit allt viktigare i vårt samhälle och beräknas fortsätta bli ännu viktigare de kommande åren. En stor utmaning för transportleverantörer är att bevara en hög kvalitetsnivå och samtidig hålla nere miljöpåverkan vilket sätter hög press på effektivisering av processerna. I dagsläget finns det få studier som undersökt möjligheten att effektivisera den faktiska transportprocessen genom styrningsmodeller som exempelvis lean. Därav syftar studien till att undersöka hur transportprocesser kan effektiviseras med hjälp av lean. Studiens teoretiska referensram består främst av Seven Waste Framework och Value Stream Mapping. Ett kvalitativt angreppssätt har använts och insamling av data har skett genom observationer kombinerat med intervjuer för att få god förståelse för processen. En anpassad metod har använts för att lättare kunna dokumentera och visualisera flödet för att få god förståelse för processen. Den anpassade metoden innebär att först utforma en VSM över processen, sedan att identifiera slöserier i processen för att till sist definiera en strategi för att effektivisera eller helst eliminera slöserierna. Resultatet av studien är att lean är ett resultatrikt verktyg för att effektivisera transportprocesser samt att VSM skapar god förståelse av processen vilket gör att lean och VSM är en framgångsrik kombination. / Transportation has increasingly become important in today’s society and is expected to continue to grow rapidly in the following years. A major challenge for transport providers is to maintain a high quality level and at the same time minimize the environmental impact, which puts pressure on the efficiency of the processes. At present, only a few studies which review the possibility to rationalize the actual transportation process through different accurate models such as lean. Therefore the study aims to review how transport processes can be streamlined using lean. The theoretical reference framework of the study consists mainly of Seven Waste Framework and Value Stream Mapping. A qualitative approach has been used and in order to give an overall understanding for the process, the data collection was made both through observations as well as by interviews. A customized method has been used to simplify the documentation and visualizing the process flow, and hence create a better understanding of the process. The steps to the customized method firstly designs a VSM of the process, then identifies waste in the process to finally define a strategy to minimize, or preferably eliminate, the waste. The study shows that lean is an effective tool for optimization of transport processes as well as VSM creates a good insight of the process, which makes lean and VSM a powerful combination.

Produktionsplanering vid förändring av en del i en produktionslina : En fallstudie i en säsongsbaserad tillverkning / Production planning with a changed part of a production line : A case study in a season based production

Andersson, Amanda, Kjellström, Lakhsmi January 2020 (has links)
En säsongsbaserad tillverkning kan innebära svårigheter för företag att möta kundefterfrågan och hålla lagernivåerna nere. En strategi för att möta en varierande efterfrågan är automatisering, vilket kan leda till en högre produktivitet och kapacitet, samtidigt som det kan begränsa flexibiliteten. För ökad flexibilitet kan gradvis automatisering av en anläggning göra det möjligt att integrera processer och få en stabil tillverkning. Arbetets syfte är att skapa förståelse för hur en förändring av en del av en produktionslina påverkar flödet i produktionen, med hänsyn till förändrad maskinutrustning och kapacitet. Målet med arbetet är att skapa en modell som möjliggör produktionsplanering i ett flöde där empirisk data inte är tillgänglig. För att svara på syftet skapades frågeställningar för att behandla hur en produktionsplanering kan göras som är baserad på empirisk teoretisk data, hur flöden bör kombineras samt hur olika faktorer påverkar buffertar och ledtider i en produktion. Genom att använda teorier om lean production och lager kunde en matematisk modell skapas. Resultatet blev en modell som med hjälp av kända variabler kunde beräkna okända samt skapa en matematisk produktionsplanering. Slutsatsen visar på att det är möjligt att skapa en produktionsplanering baserat på empirisk teoretisk data, och att modellen är tillämpningsbar även på andra industrier eftersom den är anpassningsbar. / A season based production may lead to difficulties for companies to fulfill customer demand and to keep stocks to a minimum. Changing the production can lead to a higher productivity and capacity, meanwhile it may limit flexibility. A gradual automation makes it possible to interact different processes and to make a stable production. The purpose of this project is to gain an understanding of how a changed part of a production line affects the production flow, with changed capacity and machine equipment taken into account. The goal is to create a model that enables production planning in a flow where empirical data is not available. To answer the purpose, questions of the issue were created with a focus on how a production plan can be done with only empirical theoretical data, how flows can be combined and finally how factors affect the buffers and lead time. By combining theories of lean production and inventory, a mathematical model could be created. The result was a model that with the help of known variables could figure out unknown and thereby create a mathematical production plan. The conclusion shows that it is possible to create a production plan based on empirical theoretical data, and that the model can be applied to other industries as well because of its customizability.

Implementation of Lean Tools in the Garments Industry to Improve Productivity

Hasan, Md Mehedi January 2021 (has links)
A few years back, almost every garment manufacturer industry started implementing “lean Manufacturing.” Garments manufacturing is one of the oldest manufacturing systems, compromising a higher number of critical operations. The main performance indicators in the garment industry are the lead time, production rate, more wastage, and labor intensity. To remain competitive in the global market, the most important task for garments manufacturers is to reduce lead time and waste, which is also essential for productivity and long-term stable development. A headlong rush to reduce lead time and waste by turning into lean and responsive manufacturing has created an urgency for researchers and practitioners to apply new tools and techniques for discovering wastages. This thesis focuses on the application of value stream mapping in the garments industry to implement lean manufacturing system. Value stream mapping (VSM) helps visualize Material Flow and Information Flows of all components, cycle times, and utilization of resources. VSM is a proven lean technique in identifying and eliminating wastes in accommodation with similar or identical product routings. The research approach adopted in this thesis is abductive. Qualitative has been collected by the structured and semi-structured interviews. A single case observation has been made to use VSM as a lean tool to achieve productivity improvement at a selected garment company. Both current and future state mapping of cutting section and sewing line scenarios are discussed using value stream concepts. This was analyzed along with the process lead time as standard minute value (SMV) calculation and two gaps as productive time and non-productive.  Finally, gain in productivity (increase output pcs, less worker, less working hours), increased productive time, and reduce non-productive time was calculated.
