To address the challenges of disassembly end-of-life mechanical products in complex and fuzzy environments, which complicated the sequencing of disassembly alternatives, a hybrid multi-criteria decision-making method was proposed based on INC fuzzy theory and incorporating integrated subjective and objective weights. According to dismantling features, a comprehensive optimization criteria system for evaluating disassembly sequence alternatives of end-of-life mechanical products was constructed across the environmental, economic, and human-related dimensions. Combining Monte Carlo simulation with cloud model distance, improvements were made to the cross-entropy and full consistency method to determine criteria fusion weights. The INC-measurement of alternatives and ranking according to compromise solution method was subsequently employed to rank the disassembly sequence alternatives and determine the optimal solution. Finally, an end-of-life coal-fire power products was employed as a case study to verify the scientific rigor and effectiveness of the proposed method by comparing the impacts of different weighting strategies and decision-making methods on the final results.
在系统评估和方案决策中,MCDM决策方法承担着整合多维指标信息、处理不确定性并输出可解释决策结果的重要作用,其科学性直接影响最优方案的合理性与决策过程的透明度。折中正负理想解排序(measurement of alternatives and ranking according to compromise solution, MARCOS)通过同时引入正、负理想解,构建统一的效用评价体系,能够全面地反映各候选方案和理想状态间的接近程度。
