摘要: 针对航天复杂构件生产工艺复杂、多品种小批量混流、工时长导致车间能耗大、效率低、需要频繁换刀等问题,提出一种基于改进非支配排序遗传算法(Non-DominatedSortedGeneticAlgorithm-II,NSGA-II)的柔性作业车间多目标节能分批调度方法。首先,分析航天复杂构件柔性车间能耗组成及特性,建立以总能耗、完工时间、加工成本为优化目标的航天复杂构件多目标节能分批调度模型。针对模型中优化目标相互冲突的问题,提出一种加权工序树与NSGA-II混合的模型求解算法,解决无方向性生成初始解导致算法收敛精度低、速度慢的问题,使初始解的生成具有方向性。最后,对某航天复杂构件作业车间进行节能调度优化,进行多种算法优化调度方案的对比分析,结果验证了所提模型及算法的有效性。

Abstract: To address the problems of high energy consumption, low efficiency and frequent tool changes produced by the complex production process, mixed flow of multiple varieties and small batches, long working hours in the aerospace complex components job shop, a multi-objective energy-saving batch scheduling method based on improved NSGA-II for flexible job shop is proposed. First,the energy consumption composition and characteristics of the job-shop are analyzed. A multi-objective energy-saving batch scheduling model for aerospace complex components with total energy consumption, completion time and processing cost as the optimization objectives. To solve the problem of conflicting optimization objectives in the model, a novel hybrid algorithm of weighted process tree and NSGA-II is presented. To this end, the poor convergence performance of the algorithm due to non-directional initial solution generation is handled, and the generation of initial solution is directional. Taking the aerospace complex components job-shop as an example for energy-saving optimization scheduling, and a variety of algorithms and scheduling rules are performed for comparative analysis. The results demonstrate that the proposed model and algorithm are effective.
