Effektivisering av en produktion präglad av många produktvarianter

Sammanfattning: Change is taking place all the time and it has happened as much for the last 50 years as in the entire human history. Hence changes are taking place at an ever higher rate, it is a must for companies to keep up with the development and streamline themselves to not be outdone by other companies. Companies compete with each other by offering high quality products at attractive prices with short lead times. Lean philosophy has become a widespread tool for companies to work with in this necessary streamlining work. The purpose of the work in this report is to streamline the manufacturing of elementary products at the case company. The reason has been to chart how the production process works today by performing a value-flow analysis. Our project is based on the value-flow analysis to find what deficiencies there is in the production and create an improved future position. Value-flow analysis, shortened VSM in literature, is a Lean production tool for mapping the flow of a product or service. It is a visual tool that helps identify value-enhancing and non-value enhancing parts and clearly illuminate wastes. The case company has a large product mix where many of the products undergo different processes, making it difficult to perform a proper value-flow analysis. We constrained our work to the 80/20 products and within these products found a suitable product family for our value-flow analysis, which symbolizes a large part of the case company's production. The improvements we propose mean a significant reduction of lead time within the production, which means more efficient production with lower costs and shorter delivery times. The production strategy we present that in theory leads to a significant reduction in lead time, requires further investigations and needs to be adapted to the case company's production with a high product mix before implementation.
