A Ranking Method for Reciprocal Judgement Matrix With Triangular Fuzzy Numbers
Fan Zhi-ping · Systems engineering and electronics · 2002
Reciprocal judgement matrix is a kind of preference information of pairwise comparison on alternatives given by decision makers. Decision making based on the reciprocal judgement matrix is an important topic. With regard to ranking problems on reciprocal judgement matrix with triangular fuzzy numbers, a new analysis method is presented in this paper. In the method, firstly, the concepts of the reciprocal judgement matrix with triangular fuzzy numbers and the operational rules on triangular fuzzy numbers are introduced, then the ranked value of each alternative is obtained by computing expected values of triangular fuzzy numbers. The method is simple and practical. Finally, a numberical example is given to illustrate the use of the proposed method.
