摘要:

为解决NSGA-III在求解上述模型存在初始解质量差与局部搜索效率低的问题,提出一种改进的NSGA-III(NSGA-III-TV)。基于MSOS编码,分别对OS和MS染色体采取不同混合初始化策略以提高初始解质量;基于关键路径,采用改进N6邻域结构进行邻域搜索,有效缩短完工时间并降低搜索盲目性,同时采用3种有效变异算子扩大算法搜索空间,提高后期收敛能力。结果表明:NSGA-III-TV在求解高维多目标柔性作业车间调度问题上具有较好的性能以及实用性,为企业生产制造车间的智能绿色转型升级提供了有力支持。

Abstract:

Aiming at the poor initial solution quality and low local search efficiency of NSGA-III in solving the many-objective flexible job shop scheduling model, an improved NSGA-III (NSGA-III-TV) is proposed. Based on MSOS encoding, the different mixed initialization strategies are adopted for OS and MS chromosomes to improve the quality of initial solutions. Based on the critical path, an improved N6 neighborhood structure is used for neighborhood search, which effectively reduce the completion time and reducing search randomness. Three effective mutation operators are employed to expand the search space and improve the convergence capability in the later stages. Test results show that NSGA-III-TV has good performance and practicality in solving the high-dimensional many-objective flexible job shop scheduling problems, which provides strong support for the intelligent green transformation and the upgrading of manufacturing workshops of enterprises

Key words: green flexible job shop scheduling, high-dimensional multi-objective optimization, critical path, variable neighborhood search
