摘要和关键词

摘要: 文章以某电梯钣金加工公司的钣金混流生产线为背景, 通过虚拟仿真方法对钣金生产环节中的投产序列和瓶颈问题进行优化。首先, 根据某电梯门板生产线的实际生产状况, 建立生产线的仿真模型, 以工件完工时间、设备空闲时间和设备总切换时间为目标, 基于遗传算法, 优化钣金混流生产线的投产序列; 其次, 通过分析缓存区添加位置和容量对钣金生产线产量的影响, 解决生产线堵塞、利用率不平衡等问题。结果表明, 对生产线的优化有效, 经优化后的投产序列相比原始投产序列整体时间缩短约 15%, 通过适宜的缓存区设置, 各工位设备平均利用率提高了 9.6%, 产量提高了 14.15%。

Abstract and Keywords

Abstract: Based on the sheet metal mixed-flow production line of an elevator sheet metal processing company, the production sequence and bottleneck problems in the sheet metal production link are optimized by virtual simulation method. According to the actual production status of an elevator door panel production line, the simulation model of the production line is established, and the production sequence of the sheet metal mixed-flow production line is optimized based on the workpiece completion time, equipment idle time and total equipment switching time, combined with genetic algorithm. At the same time, by analyzing the influence of added location and capacity of the buffer on the output of sheet metal production line, the problems of production line blockage and unbalanced utilization rate are solved. The results show that the optimization of the production line is effective, the overall time of the optimized production sequence is shortened by about 15% compared with that of the original production sequence, and the average utilization rate of each workstation equipment is increased by 9.6% and the output is increased by 14.15% through the appropriate buffer setting.

Keywords: virtual simulation; sheet metal mixed-flow production line; genetic algorithm; bottleneck workstation
