Abstract: The multiple hoist schedule problem is a critical issue in the design and contro l of many manufacturing processes. When the hoist number and station number are very large, finding optimal schedule is very hard. In this paper, the mathematic al model of multiple hoist schedule problem is discussed and a heuristic method about it is proposed by use of simulated annealing. A large number of examples o f random case indicate that this heuristic method is very useful, and satisfacto ry solution can be obtained with small amount of computation.%多Hoist调度在许多制造过程的设计与控制中是一个关键问题.当Hoist数与工作台数很大时, 求解调度问题非常困难.建立了多Hoist调度问题的数学模型,并利用模拟退火算法提出了一 种启发式求解方法.随机模拟的大量算例表明,该启发式方法十分有效,通过少量的计算可得 到调度问题的一个满意解.
