Abstract: Based on the theory of credibility distribution,the traditional fuzzy multi-attribute decision making approaches were extended.Aiming at the scheduling problem of fuzzy variables,three categories of fuzzy dominance models which could distinguish any fuzzy variable were proposed by comparing with the stochastic dominance method of stochastic variable model.Furthermore,the sufficient theorem of three fuzzy dominance models on ranking orders of isosceles triangular fuzzy variables was proved.Through applying the proposed method in product line's performance evaluation,the steps of fuzzy dominance model in actual production was demonstrated.The effectiveness of these kinds of dominance model was verified,and a feasible way for comparative studies of fuzzy variables was provided.
