Abstract: Fuzzy comprehensive evaluation obtains the universal application in the”clear connotation, denotation not clear" ctuestion. In order to improve the credibility of evaluation and reduce the fuzzy comprehensive evaluation of existing in the course of subjectivity, this paper, through calculating of the index to construct the information entropy of each layer of the index weights, and combinating the subjective weights of index reduced the fuzzy evaluation model of the subjective influence. Based on the revised fuzzy algorithm, this paper developed an application system and used the system as an example to verify the feasibility of the algorithm.
