主生产计划的稳定性是物料需求计划系统管理生产作业的关键问题。实现稳定性的一种方法是冷冻部分或全部MPS。虽然冻结主生产计划可以限制进度变化的数量，但它也会增加生产和库存成本。本文研究了冻结主生产计划的三个决策变量：冻结方法、冻结间隔长度和计划期长度。模拟实验结果表明，冻结高达50%的计划范围内的生产和库存成本在很宽的操作条件下有边际效应。这些结果还表明，与基于周期的方法相比，基于顺序的冻结方法产生上级结果。
The stability of the Master Production Schedule MPS is a critical issue in managing production operations with a Material Requirements Planning System. One method of achieving stability is to freeze some portion or all of the MPS. While freezing the MPS can limit the number of schedule changes, it can also produce an increase in production and inventory costs. This paper examines three decision variables in freezing the MPS: the freezing method, the freeze interval length, and the planning horizon length. Simulation experiment results are reported which suggest that freezing up to 50% of the planning horizon has a marginal effect on production and inventory cost under a wide range of operating conditions. These results also suggest that an order based freezing method produces superior results in comparison with a period based method.
