A decision making method considering multiple reviewers based on fuzzy soft set

摘要:

文章针对多方参与、评价指标有差异且存在模糊性的方案优选问题,提出了一种基于模糊软集的决策方法。这种方法首先通过将各方的评价信息应用模糊软集的“与”算子而获得满足决策者对参数要求的综合约简模糊软集表达的决策信息。在此基础上,文章提出一种应用3种不同的决策规则的方法来获得相应的最满意候选方案。最后,文章给出了具体的决策过程并通过数值算例验证了该方法的可行性和有效性。

Abstract:

The paper aims to propose a method to solve selecting alternatives problem with multiple reviewers based on fuzzy soft set. In this method, it firstly needs to get the comprehensiveSdecision making information satisfying the requirement of policy makers, which comes true by applying set from the evaluation information of the different parties. On the basis of the comprehensiveSdecision making information expressed by fuzzy soft set, we proposed a concrete algorithm based on three different decision rules to get the most satisfied with the candidate. Finally, an example and some consistency discussions of the result have been verified to test the feasibility and effectiveness.
