Layoutmodifiering i en tillverknings industri : En svensk fallstudie på Varimixer A/s

Sammanfattning: The manufacturing industry in Europe is characterized by fierce competition from Asianmanufacturers. In order to be successful, companies must develop products that are competitive. Allprocesses must be exposed in a company to improve. Large companies implement transformativechanges on a time horizon that spans 3-5 years. In order for smaller companies to maintain theircompetitiveness, these too must change for the better.Production processes need to undergo changes continuously and one way is to simulate and examinethe layout of the production. This case study looks at this problem. The case study has been carriedout at the quality and planning department at Varimixer A/S in Copenhagen. The purpose of the casestudy was to look at how production looks today with the flow of components toworkstations/machines.Interviews, observations and acquisition of data logs from the production have been used for datacollection. A mapping of overall production steps has been carried out. A literature study has beencarried out to anchor the study in the literature. After this collection of data, several futureproduction concepts were drawn up.The aim was to see how a future production flow might look purely in terms of flow in a factory. Thealgorithm used is CRAFT and uses the number of transports, workplace area and facility size as inputdata. An Excel macro has been used to carry out the simulation.Future production concepts have been picked up and show a 24% reduction in transport costscompared to the current factory. Another conceptual layout has been developed to reduce leadtimes in a new production facility with increased future volume. Here, the report shows a 13%reduction in transport costs. The focus has been on being able to reduce material handling costs infuture production in the event of a move to a new factory with all current processes.A mapping of the current production flow has been carried out. Conclusions that the author drawsfrom mapping are to point out areas that could be improved. One area that has been identified is toreduce the number of steps in machining components.
