基于混合遗传算法和仿真的后桥总成线投产顺序优化研究

Optimization of Rear Axle Assembly Line Production Sequence Based on Simulation and Hybrid Genetic Algorithm

多品种、小批量混流生产模式可以使企业适应个性化、定制化的需求,满足消费者个性化需求。合理的投产顺序能够提高人和机器的利用率,进而提高企业的生产效率。以某公司后桥装配线中的后桥总成线为例,建立最小循环周期最短模型,运用混合遗传算法求解出最优投产顺序。在此基础上,借助Flexsim仿真软件,建立后桥总成混流装配模型,对后桥总成过程进行仿真。仿真结果验证了合理的投产顺序能够降低工作站的空闲率和提高产线的产量,进而提高企业生产效率。

The multi-variety,small-batch mixed-flow production mode can enable enterprises to adapt to personalized and customized needs and meet the personalized needs of consumers.Reasonable production sequence can improve the utilization rate of human and machine,and thus improve the production efficiency of enterprises.In this paper,taking the rear axle assembly line of a company as an example,the minimum cycle shortest model is established,and the optimal production sequence is solved by hybrid genetic algorithm.On this basis,with the help of Flexsim simulation software,a mixed-flow assembly model of the rear axle assembly was established to simulate the process of the rear axle assembly.The simulation results show that reasonable production sequence can reduce the idle rate of workstations and increase the output of production lines,thus improving the production efficiency of enterprises.
