摘　　要：为了正确评估由返修回路、分装线回路和总装线回路组成的多回路发动机环形装配线的生产能力,指导后期装配线运行,对多回路发动机环形装配线进行数字化仿真与性能优化。首先分析了发动机装配线离散事件仿真的流程;然后按照层次建模法,考虑不确定因素导致的返修过程,对多回路发动机环形装配线进行详细建模;最后利用遗传算法,协同优化了不同回路中的托盘数量,提高了装配线生产性能。本方法能帮助企业更好地规划和运行多回路发动机环形装配线。In order to correctly evaluate the productivity of multi-loop circular engine assembly line,which is composed of rework loop,sub-assembly loop and main assembly line loop,and guide the operation of the assembly line,the simulation modeling and performance analysis of assembly line are carried out.Firstly,the process of discrete event simulation for this kind of assembly line is analyzed.Then,according to the hierarchical modeling method,considering the reworking,the assembly line is modeled in detail.The number of different pallets in the main assembly line loop and the sub-assembly line loop is optimized by genetic algorithm,which improves the production performance of the assembly line.This method can help enterprises better plan and operate the multiloop circular engine assembly line.
