区间数多属性决策中一种带有可能度的排序方法

为解决具有不确定性区间数的多属性决策中的方案排序问题，在考虑落在区间内的评价值（即被认为随机变量）服从正态分布的情况下，针对方案综合评价值所在的区间存在相互交叉部分的情形，提出了关于区间数之间相互比较的可能度的概念，并结合给出了有可能度的方案排序方法。通过此方法可计算出一个方案优于另一个方案的可能度。

A Ranking Approach with Possibilities for Multiple Attribute Decision Making Problems with Intervals

In order to solver multiple attribute decision making problems with uncertain intervals, a ranking method for alternatives is presented. If there are intercrosses in intervals of overall values of alternatives, under the condition that overall values (i.e.random variables) in their intervals evaluated are subjected to the normal distribution, the concept on the possibility for comparing two intervals is proposed and the according pairwise comparison matrix (i.e.the possibility matrix) on alternatives is set up. By the method given in this paper, the possibility to which an alternative is superior another can be easily obtained.
