研究了在产能受限的作业车间中,冻结区间和重排区间对主生产计划的影响,发现预测误差、需求波动、准备时间、计划提前期和订单大小对绩效影响更大,并提出了重复批次派工规则与单期订单大小组合能降低积压和库存。

Abstract

This research examines the use of both frozen and replanning intervals for planning the master production schedule (MPS) for a capacity‐constrained job shop. The results show that forecast error, demand lumpiness, setup time, planned lead time, and order size have a greater impact on the mean total backlog, total inventory, and number of setups than the frozen and replanning intervals. The study also shows that a repetitive lot dispatching rule reduces the importance of lot sizing, and a combination of repetitive lot dispatching rule and single‐period order size consistently produces the lowest mean total backlog and total inventory. The results also indicate that rescheduling the open orders every period produces a lower mean total backlog and total inventory when the forecast errors are large relative to the order sizes. This result suggests that the due date of an open order should be updated only when a significant portion of the order is actually needed on the new due date.
