随机需求下半导体生产车间的物流系统仿真优化

Simulation Optimization for Semiconductor Manufacturing Logistics Systems under Stochastic Demand

针对随机需求下具有"添加/卸除机器"特点的动态多阶段生产布局问题,建立其数学模型和批次到达速率公式.通过研究机器的添加/卸除规则,分析了添加和卸除机器事件以及3种调度准则,建立了随机需求下的仿真优化算法.通过算例验证了仿真优化算法的有效性以及仿真系统的有效性.

This paper studied a new kind of dynamic multi-stage facility layout problem under dynamic business environment,in which new machines may be added into,and old machines may be removed from the plant.A mathematical model and the batch arriving pattern were presented.By studying how to add/remove machines into/from the plant,two random events of adding/removing machines and three dispatching rules were provided.The corresponding simulation optimization algorithm under stochastic demand was presented.Finally,the effectiveness of the algorithm and simulation system was verified by real-world examples.
