The research of modeling & simulation on improving efficiency for job shop in manufacturing enterprise

This paper aimed at the cylinder head processing production line of a small equipment manufacturing enterprise, established the discrete digital simulation model of production and analyze the existing bottlenecks in the production line through the simulation run. This study raises the corresponding optimal adjusting program in accordance with the need of workshop production, carries out the comparative analysis of the facts before and after the workshop production, determines a standard method of production and the process, and then achieves to improve the production efficiency at the workshop working level, through investigating and analyzing over the line, this paper showed some measures about improving efficiency using Petri net and witness software with actual conditions. Then construe the results about theoretic and figures. These methods improved the efficiency of enterprise after the enterprise using them.
