基于结构熵权—灰关联的绿色供货商评价与选择研究*

为了解决评价选择过程中的不确定性、复杂性等问题,将定性与定量方法相结合,建立了供货商评价与选择指标体系,并提出了一种基于结构熵权—灰关联的绿色供货商评价决策模型。基于熵理论,采用主、客观赋值结合的结构熵权法获得指标综合权重;再使用模糊评判和灰关联,获得结果的关联度排序;最后借助算例验证了模型的有效性,为评价绿色供货商提供了有效的方法。

Research on evaluation and selection of green supplier based on structure entropy-grey correlation

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.
