Abstract:

Aiming at the shortage of IPPS problem in multi-objective optimization, multi-objective optimization was integrated into IPPS problem. The makespan, processing cost and maximum machine workload were the main targets which will be optimized. The model was built for multi-objective integrated process planning and scheduling problem. A non-dominated sorting genetic algorithm (NSGA-Ⅱ) was proposed for the problem. A multi-layer structure was used to represent solutions. Selection and genetic operators are designed in the algorithm. Finally, the model and algorithm were proved through an application case.

Key words: integrated process planning and scheduling, multi-objectives, non-dominated sorting genetic algorithm, selection

摘要:

针对工艺规划与调度集成问题在多目标优化方面的不足,考虑将多目标优化集成到工艺规划与调度集成问题中。以最长完工时间、加工成本及设备最大负载为优化目标,对该多目标工艺规划与调度集成问题进行建模,并提出了一种非支配排序遗传算法,鉴于加工信息的多样性,使用多层结构表示可行解,对该算法的选择及遗传操作等步骤进行了设计。最后,以实例验证了上述模型的正确性及算法的有效性。
