本文指出了单独使用特尔斐法、集值统计法或层次分析法确定各评价指标权重的优缺点。通过实例,说明了联合使用特尔斐法与层次分析法求权重的合理性,即:(1)构造各层因素的权重判断矩阵时用特尔斐法;同时指出了分级定量法赋值的极端性。(2)计算权重时用层次分析法;同时提出了通过判断矩阵求权重的一种精确、简便的方法——求最大特征根迭代法。 This paper points out the advantages and disadvantages of using the Delphi method, the set-valued statistics method or the analytic hierarchy process to determine the weight of each evaluation index. Through examples, the rationality of using the Delphi method and the AHP to calculate the weights is illustrated, namely: (1) The Delphi method is used to construct the weight judgment matrix for each layer of factors, and the extremes of the assignment of the hierarchical quantification method are pointed out at the same time. Sex. (2) When the weights are calculated, the analytic hierarchy process (AHP) is used. At the same time, an accurate and simple method for finding the weights through the judgment matrix is ​​presented.
