ABSTRACT

In an assembly line system, the production process may suffer a sudden disruption, and this may call for rebalancing. In this paper, the assembly line rebalancing problem is set in a multiperiod context considering stochastic processing times. It is assumed that there are specific moments in time chosen for rebalancing the line (if necessary). Two policies, a periodic rebalancing policy and a data-driven rebalancing policy, are proposed to solve the rebalancing problem. The goal is to minimize the total cost, which include production and rebalancing costs. An empirical study is conducted, and several results are achieved: rebalancing an assembly line is sometimes worse than not rebalancing it; rebalancing an assembly line too often may not be beneficial; and the new data-driven policy introduced is better than the plain multiperiod policy.

重新平衡装配线与中断的新方法

摘要

在装配线系统中,生产过程可能会突然中断,这可能需要重新平衡。在本文中,装配线再平衡问题被设置在考虑随机处理时间的多周期环境中。假设选择了特定的时间来重新平衡生产线(如果需要)。提出了两种策略,即周期性再平衡策略和数据驱动的再平衡策略来解决再平衡问题。目标是最小化总成本,包括生产和再平衡成本。进行了一项实证研究,并取得了几个结果:重新平衡装配线有时比不重新平衡更糟糕;过于频繁地重新平衡装配线可能没有好处;引入的新数据驱动政策优于普通的多周期政策。
