基于AHP与改进DEA方法的机械产品绿色度评价研究

Study on Evaluation Method of Green Degree of Mechanical Products Based on AHP and Modified DEA

阐述了产品绿色度的内涵,建立了机械产品绿色度评价指标体系,改进了传统数据包络分析方法存在的不足.将层次分析法与改进的数据包络分析法相结合,建立了绿色度评价模型,结合实例计算出产品绿色度,并与基于协调分析法的评价结果进行比较,以验证该法的有效性,并给出绿色度评价系统实例.

The connotation of product green degree is expounded and the evaluation index system for mechanical products is built. While the deficiency of the traditional method of data envelopment analysis is improved. Then an evaluation model is established based on analytic hierarchy process and modified data envelopment analysis, and then get the evaluation result of mechanical product. An application validates the efficiency of the proposed method combining the evaluation result from coordination analysis method and gives the evaluation system of instance.
