柔性制造系统重调度的仿真建模与分析
Modeling and Analysis for Rescheduling in the Flexible Manufacturing System

在订单型生产系统中，订单的订货量和交货期等内容的变更会干扰原有的调度计划，从而需要进行重调度。以一个包含6个操作阶段的柔性制造系统为背景建立了重调度模型，模型以订单延误数和开工时段发生变化的订单数为双重优化目标。针对此重调度模型，运用仿真软件模拟了调度和重调度的过程，研究了向右顺延和紧挨交货期交换两种重调度的规则，并根据仿真结果比较了这两种规则的运行效果。分析表明：紧挨交货期交换规则在两个目标上都取得了更好的效果。
A two-objective model was constructed for rescheduling problem with order modification in make-to-order flexible manufacturing system. The present model was designed to minimize both the tardy orders and the differences between rescheduling result and original sequence. The simulation models were built to imitate the running of scheduling and rescheduling scenes, and two rescheduling rules, right-extending and swapping to a period near due date, were proposed for the bi-objective rescheduling model. Running of rescheduling models was conducted. The results revealed that the rule of swapping to a period near due date achieved better performances than the right-extending rule
