Fuzzy多判据决策

Fuzzy Multi Criteria Decision

在多判据情况下，对几个备选方案作排序选优，较典型的模糊决策方法有模糊关系法、模糊评价法等．本文将这两种方法结合起来，先分别在单判据情况下，对方案作模糊评价，建立优于关系，然后再综合．本方法便于作灵敏度分析，便于在计算机上实现，使决策能在交互式过程中反复进行，从而得到较符合实际，满足决策者意愿的最佳方案．

In the case of multi criterions,the methods of relative model fuzzy decision which are used to rank and pick out the best from several substitute projects include the method of fuzzy relation, the method of fuzzy evaluation and so on.By combining the two methods above,the paper first makes a fuzzy evaluation for the projects,sets up the major relation in the case of single criterion,and than makes a synthesis in the case of multi criterions.The method can easily be used for sensitivity analysis and realized by computer,and also has decision made mutually repeatedly.Therefore,the method can obtain the best project which comparatively conforms to reality and satisfies the decision-makers'intentions.
