用模糊物元模型评价电力上市公司的财务业绩

Fuzzy Matter-element Model for Electric Power Market Company's Finance Outstanding Achievement

在模糊物元分析原理的基础上,结合协商定权和熵权的理论方法以及海明贴近度的概念,提出了基于主客观权重和海明贴近度的模糊物元分析方法.在对电力上市公司财务业绩进行综合评价时,把不同电力上市公司作为物元的事物,以它们的各项评价指标及其相应的模糊量值构造复合模糊物元,通过计算与理想模糊物元之间的海明贴近度,实现对电力上市公司财务业绩的综合评价.

In order to evaluate the electric power market company＇ s finance outstanding achievement,a new method is put forward based on the fuzzy matter-element analysis and combined with the concept of Simdilar approach degree, the theory of bargaining weight and entropy weight,regarding the electric power market company as the objects of matter-element and the compound fuzzy matter-element is constructed with the evaluation factors and their fuzzy value of the object. Through calculating Simdilar approach degree between the fuzzy matter-element and the standard（the best） fuzzy matter-element,the ecological level of electric power market company＇ s finance outstanding achievement is realized.
