基于区间值Vague集的多准则模糊决策方法

Multicriteria Decision-Making Based on Interval-Value Vague Sets

给出i-v V ague集的含糊度定义,将实数型V ague集群决策的记分函数方法扩展到区间值V ague集上,用实例比较各种记分函数方法的优缺点.然后给出两种改进的记分函数法和加权记分函数法,并通过例子阐明改进方法的有效性和优越性.

Gives an uncertainty definition for i-v Vague sets, and extends the score function of real number Vague set group decision to i-v Vague sets. Moreover, after comparing all kinds of score functions with examples, two new methods： viz. , the score function and weighted score function methods are compared and it is shown that the two improved methods are more efficient and advantageous.
