Financing risk credit evaluation model of the electric power enterprises based on rough set and entropy

Since electric power companies listed, the quality of financing ability would directly affect the effective operation of these companies. This article takes electric power listing companies as research object, selected 41 financial indicators coming from 10 electric power companies as the study sample. Firstly, using rough set to attribute reduction, then evaluated the model based on entropy, mixed these complicated problem into a unified whole to comprehensive analysis, introduced the entropy weight evaluating model which can turn the disorder comparable information into the orderly comparable information. It has great realistic significance to evaluate the electric power companies' financing ability.
