摘要: 针对实际拆卸线中涉及的资源约束和危害零件问题,以资源总数、工作站数和危害指数为目标函数,构建了多目标资源约束拆卸线平衡问题数学模型。基于AND/OR关系,在优先关系矩阵中添加OR关系的描述,解决了产生初始解仅考虑AND关系的不足问题。提出了一种融入Pareto思想的改进混合蛙跳算法  ,该算法采用基于满意度的改进排序分组策略来解决多目标优化种群分组问题;提出了一种新的交叉变异方式进行局部搜索以提高收敛性能;利用拥挤距离机制评价非劣解集以及有效地维护外部档案容量。采用田口实验和统计分析方法确定了算法最佳参数组合,将改进前后的混合蛙跳算法及NSGA-Ⅱ对测试算例的求解结果进行了多指标对比分析,研究结果表明:改进混合蛙跳算法具有良好的综合求解优势。最后,将所提算法应用到某电冰箱的资源约束拆卸线平衡问题中,为决策者提供了较优的拆卸方案。

Abstract: Aiming at the resource constraints and the hazardous parts involved in the actual disassembly lines, a mathematical model of multi-objective resource constraint disassembly line balancing problem was constructed considering the total number of resources, the number of stations and the hazard as index three objective functions to be optimized. Based on the AND/OR relation, the descriptions of the OR relation were added to the priority relation matrix, which solved the problems that the initial solution only took into account the AND relation. An improved SFLA incorporating the Pareto's idea was proposed. An improved ranking grouping strategy was adopted based on satisfaction to solve the multi-objective optimization population grouping problems for the proposed algorithm. A new cross-mutation method was proposed to implement the local search to improve the convergence. The crowded distance mechanism was used to evaluate the non-inferior solution sets and effectively maintain the size of the external file. And Taguchi experiment and statistical analysis method were used to determine the optimal combinations of algorithm parameters. The multi-index was used to compare and analyze the results of the testing instances obtained by the SFLA before and after the improvement as well as the NSGA-Ⅱ. The research results show that the improved SFLA has a good comprehensive solution. Finally, the algorithm was applied to a refrigerator disassembly line, which provided a better solution scheme for decision makers.

Key words: disassembly line balance problem, resource constraint, improved shuffled frog leaping algorithm(SFLA), multi-objective optimization
