Abstract: Aiming to deal with those problems that the fuzzy membership degree which acts as the state function dose not satisfy the normalization and additivity, and the max-min operation of fuzzy sets will lose a lot of useful information in the evaluation of the venture investment, in this paper, the Bayesian theory and the three-way decisions was introduced into the fuzzy comprehensive evaluation model. A risk factor was defined with the risk function and a new risk evaluation matrix was constructed, then a new evaluation model of venture investment was proposed based on the risk minimization of three-way decisions. After that, the minimum loss decision is taken according to the risk minimization principle, thus the problems existing in the fuzzy comprehensive evaluation method are solved and the evaluation results are more reasonable and more accurate.

Key words: risk minimization, three-way decision, fuzzy comprehensive evaluation, venture investment
