摘　　要：合理的供料策略对装配线运行的效率和成本有很好的优化效果。本文研究了装配线平衡、物料供应策略的集成优化问题,同时兼顾操作者的人因负荷。首先,考虑对装配线所需各物料采用直接或间接供料策略,并采用能量消耗率和脑力承受度来客观评估操作者的体力与脑力负荷,以解决传统人因学评估方法由于量纲问题而导致的目标函数难以获得精确最优解问题;然后,以最小工位数、最小化平滑指数为优化目标,构建了装配线平衡模型;最后,结合实例,并通过遗传算法求解,分析了分层优化和集成优化的优缺点,这为实际生产中通过优化供料方式来提高经济效益、保护工人健康提供了一定的研究思路。Reasonable feeding strategy has a good optimization effect on the efficiency and cost of assembly line operation.This paper studies the integrated optimization of assembly line balance and feeding strategyand considers operators’ the ergonomic load,while it ’ s difficult to obtain a precise and optimal solution through traditional human factors methods due to dimensional issues.Then,an integrated optimization model is constructed with the minimum operator number and the minimum total smoothing index as the optimization goal.Finally,genetic algorithm is used in a case study.The advantages and disadvantages of bothlaycredoptimization and integrated optimization arc analyzed.The study paves a new way to improve economic benefits and guard workers’ health by optimizing the feeding method in actual production.
