    摘要:

    针对退役产品拆解工艺与物流存在的不确定性,提出一种逆向生产和物流集成调度拆解车间优化方法.分析退役产品拆解车间作业过程中生产与物流相互影响因素,以优化逆向生产与物流过程中的最大完工时长和提前/拖期成本为目标构建车间多目标调度模型.基于物流路径决策,设计一种带基因修复的变异算子改进NSGA-Ⅱ算法的变异准确性,提升算法的求解有效性.以某公司的手机拆解线为例,分析多尺寸的生产、物流算例.结果表明,随着自适应引导车数量的增加,大、小尺寸算例的拖期成本分别减少了57.1%和58.3%,验证了模型的有效性.

    Abstract:

    Aiming at the uncertainty of disassembly processes and logistics, an optimization method for the production and logistics integrated scheduling in a disassembly workshop is proposed to cooperatively optimize efficiency and cost. Firstly, the interaction factors between reverse production and reverse logistics in end-of-life product disassembly workshops are analyzed. A multi-objective scheduling model of the workshop is constructed, aiming at optimizing the maximum completion time and the advanced/delayed costs in reverse production and workshops logistics processes. Secondly, based on the logistics route decision, a mutation operator with gene repair is designed to improve the mutation accuracy of the NSGA-Ⅱ algorithm and enhances the solution effectiveness of the algorithm. Finally, taking a company's mobile phone disassembly line as an example, the multi-size production and logistics examples are analyzed. The results show that as the number of adaptive guided vehicles increases, the delay cost of large and small size examples are reduced by 57.1% and 58.3%, respectively, verifying the effectiveness of the model.
