摘　　要：根据专家给定的不确定型判断矩阵,形成专家评判矩阵的上、下限矩阵;然后,由各专家评判矩阵的上、下限矩阵首尾相接形成对应的行向量;最后,计算各专家对指标判断的上限、下限矩阵行向量与其他各专家评判的上限、下限矩阵行向量的相关度,并以每位专家评判结果与其他专家评判结果相关度的平均值作为专家评判结论的可信度.与其他方法相比,这种基于灰色相关性分析的AHP中群组评判的可信度计算方法的计算结果具有较高的精度.Upper and lower bound matrixes are formed according to researchers＇ indeterminate judgment matrix; secondly, row vector is obtained from the above bound matrixes for every researcher; finally, grey relation coefficient of judgment result of every expert and other experts are calculated, the average of the grey relation coefficient is as the researchers＇ certainty factor. The proposed method considered the certainty factor of the judged upper and lower bound, the method in this paper is more convenient, the result compared to the other method showed high accuracy.
