Abstract

Abstract: Value Stream Mapping is an effective tool to identify and reduce waste in the production system. TOC is the theory to find the bottleneck of the system and improve the effective output of the system. Based on the improvement of the production system of a sprocket workshop, the waste in the production system is identified through the Value Stream Mapping analysis, and the TOC method is used to identify bottleneck resources, and then the related theories of improved SLP, SHA and lean production applied to explore the general method of improve manufacturing production system, and specific suggestions put forward. Finally, the Witness simulation model is built, and validation shows that the improvement effect is obvious. The improvement plan of production system proposed has a positive and practical significance for the improvement of workshop production system and can provide some reference for the improvement of workshop production system of the same type of manufacturing enterprises.

Key words: theory of constraints(TOC), systematic layout planning(SLP), system handling analysis(SHA), value stream mapping(VSM), Witness simulation
