An Effective Aggregation Method for the AHP Judgement Matrix in Group Decision-Making
群组AHP判断矩阵的一种有效集结方法

To solve the aggregation problem of the judgement matrices in Group Decision-Making,An improved aggregating method about the reciprocal matrices is presented, which is based on the theory of the m-th power graph of simple undirected connected graph.Finally the applied steps of the proposed approach are described and numerical examples are given to illustrate the effectivity of the method.
