This paper proposes risk evaluation system of metro project bidding based on factors which the environment and process of metro project bidding involved. Then the paper uses the entropy value method to determine the weights of the index and adopts Fuzzy to evaluate risk management level of metro project bidding, which takes the vagueness and uncertainty into account with a combination of both methods. According to the evaluation results, the paper puts forward recommendations for improvement and verifies the feasibility of the evaluation model. KEYWORD: Bidding of Metro Project; Risk Management; Entropy Value Method; Fuzzy International Conference on Industrial Technology and Management Science (ITMS 2015) © 2015. The authors Published by Atlantis Press 1170 It conducts expert evaluation to index by using fuzzy matrix, then quantifis the results of the final evaluation through composite operations. It evaluates membership grades of indicators with a number of factors taken into account. 3 THE RISK EVALUATION SYSTEM OF METRO PROJECT BIDDING 3.1 Establishment of Index System According to fators exist in process of metro project bidding, the paper analyses all links that affect safety of metro project from aspects of behavior and environment of implementation. Evaluation index system is shown in figure 1: The evaluation system of risk management in metro project bidding defects of tender documentation C12 wrong decision of tenderee C11 ability to comply with the agreement of the tenderee C14 defects of tender organization C13 analysis and response of changes in policy C32 changes of the price C31 environmental adaptability analysis of the potential bidder C33 Risk of bidding environment C3 Risk of tenderee behavior C1 similar experience of project contract C22 qualification of bidder C21 bidder gives up the winning bid C24 bid-rigging,low price tender and other bad behaviors in bidding C23 Risk of bidder behavior C2 Figure1. The evaluation system of risk management in metro project bidding. 3.2 Determination of Index Weights Use entropy method to determine the weight of each factor index in index system. The specific operation process is shown as follows: (1) To calculate the importance of metro project bidding risk indicators in evaluation system decision-making data is obtained through research which construct the decision matrix   ij m n R r   .Then the decision matrix must be standardized by
