Simulation and Optimization of Production Line in Em-plant based Assembly Workshop

Abstract

Taking the dynamic production of a line in the assembly shop of a company's rear axle as an example, the on-site investigation confirmed the basic data and analyzed the assembly process. Em-plant software was used to model the dynamic simulation of each station on the assembly line. According to the simulation results, the bottleneck process is improved, and combined with ECRS principles in lean production, it is eliminate, combine, rearrange and simplify. Under the actual production conditions, an optimization scheme was proposed. After the improvement plan was implemented, the simulation results showed that the production capacity was significantly improved, the assembly line imbalance was improved, and the company's efficiency was improved.
