Abstract

Abstract: Because the influence factors in the selection of old bridge's reinforcement porposals is fuzzy,the comprehensive evaluation method is proposed in decision making of reinforcement project.The paper introduce the math model and process of this methoh in detail along with some example for test.The result shows that method is simple and useful,worthy of referring.

Key words: fuzzy comprehensive evaluation, the optimal selection of bridge's reinforcement project, influence fator, subjection degree, weight
