一种基于序区间偏好信息的群决策分析方法

An Analysis Method of Ranking in Group Decision Making Based on Ordinal Preference Information

针对序区间偏好信息的群决策方案排序问题,本文提出了一种新的分析方法.首先,给出了序区间的有关定义及其性质;然后,通过定义专家群体判断关于方案在排序位置的期望可能度和专家群体判断关于方案的数学期望值,给出了序区间偏好信息的群决策方案排序方法.最后,通过一个算例说明了本文提出的分析方法。

With respect to the problem of ranking in group making based on ordinal preference information,in this paper,an analysis method is proposed.Firstly,some concepts and characters of ordinal preference information are introduced.Then,based on introducing the conceptions of expected ordinal interval possibility and expected ordinal interval value,an analysis method of ranking in group decision making based on ordinal preference information is proposed.Finally,a numerical example is given to illustrate the use of the proposed analysis method.
