| 摘要: |
| 退役工程机械产品再制造不仅延续了产品的生命周期，而且有利于资源再利用及生态环境保护，并具有巨大的经济价值。目前对回收后的退役产品的绿色性评价研究多将环境和经济因素进行分开评价，将两个因素合并成一个统一评价尺度量值的研究较少。以某工程机械企业再制造过程为研究对象，提出多属性效用决策方法构建绿色性评价的多目标决策模型，采用总效用值对绿色性进行度量。运用生命周期评价、生命周期成本的集成思想建立了绿色性评价指标体系，包括资源、生态环境、人因和经济等方面因素。最后，通过实例分析了退役产品再制造修复方案的绿色性效用值计算过程。该方法模型可为再制造企业选择最优的处理方案以及再制造加工工艺提供决策支持。 |

| Abstract: |
| Remanufacturing of retired construction machinery products has not only extended the life cycle of the products, but also taken in some advantages, such as the reuse of resources, the ecological environment protection and great economic benefits. However, numerous researches on green assessment of the recycled products took the environmental and economic factors into consideration separately so far, it was rare to integrate the two factors into a unified evaluation scale research of the value. Therefore, a multiattribute utility decision method was put forward to build the green evaluation of multiobjective decisionmaking model which ultilizes the total utility value to measure the size of the green performance by taking the recycling and remanufacturing process of certain construction machinery remanufacturing enterprise as the research subject. Then, the green evaluation index system which contains the thought of integrating, life cycle assessment and life cycle cost assessment was built, including resources, environment, ergonomics, and economy factors. Finally, the calculation process of green utility value for the remanufacturing repair was analyzed through a relevant case. The model can assist remanufacturing enterprises to choose the optimal treatment and provide decision support for the selection of different remanufacturing process technology. |
