Abstract Remanufacturing is an important mode to promote the sustainable development of manufacturing industry. Remanufacturing mechanical components at the best recycling time can effectively reduce the remanufacturing cost and improve the remanufacturing efficiency. Therefore, the decision-making model of optimal recycling time based on full lifecycle assessment and full lifecycle cost method was firstly established to analyze and model the energy consumption, cost and emission of components in the original manufacturing, usage, remanufacturing and reuse stages. Then, a remanufacturing evaluation method based on fuzzy extension analytic hierarchy process was proposed. Considering a variety of uncertainties of waste components, a qualitative and quantitative evaluation index system was established, and the weight of each evaluation index was determined by expert evaluation and fuzzy comprehensive evaluation method. Finally, a boom cylinder of a concrete pump truck was studied. The boom cylinder recovered by the method proposed has a high recovery value, and its comprehensive score reaches 70, which verifies the effectiveness and superiority of the model.

基于模糊EAHP的旧工程机械零件再制造性评价方法及应用

摘要 再制造是促进制造业可持续发展的重要方式。在最佳回收时间对机械部件进行再制造,可以有效降低再制造成本,提高再制造效率。为此,首先建立了基于全生命周期评估和全生命周期成本法的最优回收时间决策模型,对零部件在原始制造、使用、再制造和再利用阶段的能耗、成本和排放进行分析和建模。然后,提出了一种基于模糊可拓层次分析法的再制造评价方法。考虑废弃物成分的多种不确定性,建立了定性定量评价指标体系,并通过专家评价和模糊综合评价法确定各评价指标的权重。最后,对混凝土泵车臂架油缸进行了研究。所提方法回收的动臂油缸具有较高的回收值,综合得分达到70,验证了模型的有效性和优越性。
