The Study Basic On The Simulation Technology Of Production System Balance In The Automotive Assembly

As one of important branch of Industrial Engineering,the manufacturing facility design is to organize the facility of enterprise to improve the utilization of enterprise resourcesto achieve the efficient performance. With rapidly development of system simulation technique,using simulation technique to the design,verification and analysis phases of facility design plans can effectively avoid risk of changing real facility layout.In this paper, the research object is the assembly shop of one trunk manufacturing enterprise.We discuss the technique of facility layout and logistic simulation,analyze the principle and use of logistic simulation software Pro-Model,build the simulation model of shop,analyze and modify the model to increase the throughput and reduce WIP(work in process).Firstly, we introduce the theory of facility layout design and its evaluation system;and use these technique to analyze real workshop.Secondly,we introduce the application of system simulation in facility layout, and use simulation software to build the model of workshop.Through analyzing the simulation result to get the production case of the workshop and find the problems of real facility layout and production process.At last,in order to increase throughput and reduce WIP,we use systematic layout planning and line balance method to improve the facility layout and production line of the workshop,propose the improvement plan and build and run its simulation model. The results of simulation show that the improvement plan can achieve the objective of reducing WIP and increasing throughput,and it is important for the enterprise to have a decision support.
