基于Vague集的多准则模糊决策方法

Multicriteria Fuzzy Decision Making Method Based on Vague Set

基于Vague集的模糊决策方法的提出,为决策系统提供了一个有用的工具.对模糊条件下的多准则决策问题,指出了采用Vague集进行多准则模糊决策的现有计分函数的不足,根据Vague集的性质提出了二种新的方案选择方法:记分函数法和加权记分函数法.对已有的Vague集记分函数法进行了分析与联系,并通过例子阐明本文方法的有效性和优越性.

Fuzzy decision making method based on vague set provides a useful tool for fuzzy decision making system. Based on vague set theory, two methods handling multicriteria fuzzy decision-making problem are provided. They are called score function method and weighted score function method. Moreover, we analyze the present methods connected with vague sets and show by examples that the methods presented in this paper are more efficient and advantageous.
