Application Research on Rough Set and Analytic Hierarchy Process in Fuzzy Comprehensive Evaluation

摘要：

Aiming at disadvantages of fuzzy comprehensive evaluation (CE) in weight determination, according to rough set theorem and analytic hierarchy process, a weight determination method of complete data driving is presented, and improved fuzzy CE model is obtained.At first, evaluation index system is formed according to analytic hierarchy process. Then index system is rediced effectively by the use of attribute reduction in rough set theorem, and redundant attributes are deleted. Based on the concept of inclusion degree, we define attribute importance, and present determination method of weight. According to which, fuzzy CE model is.formed therefore a new method of CE is acquired.Finally, this method is proved to be practical and feasible through examples.
