主生产计划不稳定性的模拟研究

Simulation Study on Instability of Master Production Schedule

在能力受限的滚动式计划环境下，研究冻结参数和计划算法在不同生产条件下对主生产计划不稳定性的影响。通过模拟实验及统计分析发现：冻结比例、费用结构、能力松紧度、计划算法和计划长度对主生产计划不稳定性有较大影响，且交互作用显著。研究结果对减小主生产计划的不稳定性有一定指导意义。

Under capacitated rolling-horizon scheduling, a simulation is conducted to study the impact of the freezing parameters and the scheduling algorithms on the instability of the master production schedule in different production environments. Numerous simulation experiments and statistical analyses show that the impact of freezing proportion, cost structure, capacity tightness, scheduling algorithms and planning horizon on the instability of the capcitated master production schedule is siginificant, and the interactive effects between them are also siginificant. These results are useful when practitioners intend to reduce the nervousness of their production schedule by selecting optimal or reasonable freezing parameters and scheduling algorithms under their own prodution conditions.
