Research on evaluation and selection of green supplier based on structure entropy-grey correlation
基于结构熵权—灰关联的绿色供货商评价与选择研究*

In order to solve the uncertainty, asymmetric information and other issues, constructed the indexes system of estimation and selection by combining qualitative analysis and quantitative analysis, and proposed a supplier estimation and selection model based on structure entropy weight-grey correlation. First, obtained index weight by the structure entropy weight method which belonged to the subjective assignment and objective assignment method based on the entropy theory. Then, used the fuzzy evaluation and grey correlation to obtain the correlation order of results. Finally, validated the reasonability of the model through an example. It provides an effective way for quantitative evaluation of the supplier estimation.
