A New Method on Group Decision-Making with Interval-Number Judgment Matrices
Sifeng Liu · Zhongguo guanli kexue · 2004
With regard to the group decision-making under interval-number judgment matrixes,a new method is proposed.Based on the theory of set-value statistics,a new judgment matrix consisting of some defining-numbers with certain reliabilities is constructed equivalent to judgment matrixes with interval-number,and the model of computing and revising the reliable degree of the aggregated values of group information is established.A simple algorithm for rnaking alternatives is given through dealing with the new judgment matrix by the sum-product method.Finally,a numerical example is used to illustrate the validity and the application of the method.
