流,缩短原材料供货周期,减少工段的在制品库存,从而提升整条生产线的增值比,增值比由2.11%提升至3.56%,提升了生产线的生产效率。其次是作业分析,针对瓶颈工序活门组装,进行双手作业分析,减少左右手的等待时间,从而缩短瓶颈工序的作业时间,提升工序的生产平衡率,工序的生产平衡率从61.41%提升至80.26%,使工序生产平衡率达到良的标准。

(2)遗传算法用于优化工段的生产平衡率。利用Python软件设计遗传算法优化方案。首先设置目标函数,要求生产平衡率越高,生产平滑指数越低。其次是初始化种群设计,绘制生产工序逻辑关系与优先关系矩阵。再次设置选择、交叉与变异操作。最后运行遗传算法,得出最优的运行结果。重新分配工段的工序后,工段的生产平衡率提升至97.50%,平滑指数降低为0.67。

(3)运用FlexSim仿真,将生产线改善前与改善后的生产线进行模拟,对比分析仿真结果。改善前人员利用率工段1为100.00%,工段2为82.85%,工段3为84.85%,工段4为77.96%,每日产能为17台。改善后人员利用率工段1为100%,工段2为95.55%,工段3为96.11%,工段4为97.38%,每日产能为20台。经过优化,生产线各工段的人员利用率与生产线产能都有明显提升。
