Sammanfattning: Company A is a company based in Skövde with headquarters in Lidköping. They are world leaders in ventilation units that purify air in a production environment. They have subsidiaries in Germany, the United States, China, and France. The company is currently undergoing a transition from contract production to mass production. This degree project has been carried out on assembly line 1, where the work is limited to the assembly's work with product A. Product A is the most produced model in assembly line 1. The assembly line consists of four different stations manned by one person at each station. The work performed is manual work. The purpose of the project is to theoretically reduce all stations cycle time to less than 20 minutes. To enable this, a current state analysis is performed with the support of production engineering tools and methods. The improvement proposals are based on the data collected with these. The study was conducted using observations such as Genchi Genbutsu, spaghetti diagrams of the operators' movement in the various work steps, balancing scheme for operator showing the value-adding, non-value-adding and necessary non-value-adding time and time studies that produce the correct standard time for the work steps using the snapback method. A preference matrix has been developed to facilitate the future balancing of the assembly line. The improvement proposals presented reduce the lead time by 23.1% and the theoretical cycle time to less than 20 minutes on each station.
