残缺互补判断矩阵排序的一种新方法

对残缺互补判断矩阵的排序方法进行了研究.把一般互补判断矩阵的排序方法推广到了残缺判断矩阵的情形,分析了参数的取值范围,并对判断信息完全未知的情形进行了讨论.最后给出了算例,对几种排序方法作了比较,结论表明本文给出的方法权重差异较大,更易于方案的排序.

A New Ranking Method of Incomplete Fuzzy Complementary Judgment Matrix

This paper discusses the ranking method of incomplete complementary judgment matrix.A new method is proposed based on the theory of fuzzy complementary judgment matrix and the range of the parameter is discussed.An analysis is given to the situation where the judgment information about the alternatives is completely unknown.Finally,an example is given to illustrate the method.By compared several methods,the results show that the difference of the priority vector used by the proposed method in this paper is larger than the others,so we can choose the best alternative easier.
