基于数据包络分析模型的绿色产品非均一评价

Non - uniform Assessment Method of Green Products Based on DEA

提出了基于数据包络分析模型的非均一综合评价方法。先构造一个技术参照产品,利用数据包络分析模型评价各产品相对于参照产品的绿色属性,利用决策单元在有效前沿面上的投影理论,定量地给出了提高产品绿色属性的技术改进方法。利用实例说明其使用方法并证明其有效性。

After analyzing the shortcomings of comprehensive assessment methods for green products, this paper presents a non - uniform assessment method based on DEA (Data Envelopment Analysis) model. It is used not only to assess the greenness of products with regard to technical reference product that is constructed through the information of products, but also to give how to improve the greenness of products quantitatively by utilizing the project theory on DEA efficient frontier of DMU (Decision Making Unit). At last a numerical example shows how to use the method and prove its availability.
