An Individual Inner Evaluation from Two Kinds of Groups of Pairwise Comparison Matrices

Abstract

This study assumes a group of the individuals and aims to obtain each individual inner evaluation from the intuitive judgments by a group of experts. The intuitive judgment is given as a comparison matrix of the multiple criteria and the inner evaluation is obtained as a fuzzy weight vector. Two kinds of the groups are considered: the judgments on the target individual and those by each expert. The inner evaluation of the target individual is simply obtained as the core of the former group. Furthermore, we compare the judgment on the target by an expert with those on all the other individuals by the expert to reflect his/her judgment characteristic. The relation among the judgments in each group is constrained by the inclusion relation and it is relaxed for a fuzzy weight vector.
