Algorithm of Solving Weights for Group Decision Making by Improving Compatibility
基于相容性修正的群组决策排序算法

An index of the compatibility of the group decision making was given. By the idea of minimizing the compatibility of the group decision making, a mathematical model of solving the weights of the group decision making was gained. And the we proposed an algorithm to modify a pair of elements of the expertjudge matrixes, by which the compatibility of the group decision making was less than that of the original one. Then the convergence theorem for this algorithm was established and its practicality was showed by examples. The presented model and algorithm are much more precise that common methods. These can be applied to Group DSS widely.
