Flödesanalys och kontroll av ett Job-shopproduktionssystem

Abstract

Today’s industry is changing rapidly, and the demand for customized products with shorter lead times is growing. This bachelor thesis aims to analyze a company’s production system in order to identify bottlenecks and provide improvements in the production flow. The study was carried out through proved methods within lean, layout planning, and discrete event simulation. The data was modeled in Tecnomatix Plant Simulation, where the simulated model was verified and validated against the real production data to ensure accuracy. The results show that the sawing station creates significant bottlenecks and causes blocking, which prevents the whole system from working effectively. The analysis also demonstrates that machine placement and transport distances play an important role in lead time. An alternative layout was developed according to lean philosophy and the SSLP-method to improve production rate, utilize space, and create an efficient flow. The findings show that optimizing layout design and balancing cycle times can improve the overall performance and efficiency of the production system.
