摘　　要：层次分析法(analytic hierarchy process,AHP)被广泛应用于多准则决策分析中.但是,采用AHP方法构造出的判断矩阵(comparison matrix,CM)不容易满足一致性的要求.本文采用改进的AHP对元素按重要程度进行排序赋值来构造CM.通过对明挖地铁车站的风险源进行辨识,利用改进的AHP能有效地提取信息,方便快捷地构造判断矩阵,提高风险辨识的准确性.该方法计算出的风险源分布情况和已有的统计调查结果基本符合.The analytic hierarchy process（AHP） approach is applied to solving multi-criteria decision-making（MCDM） problems in many areas.However,the comparison matrix（CM） is not ＂consistent＂ within a limit of a consistency measure.An improved AHP（IAHP） is proposed to improve CM consistency by using a sorting methodology to determine CM.A case study is presented to illustrate the advantages,in terms of CMs consistency and information extraction effectiveness,when IAHP was applied to risk identification during an open-cut subway construction.The distribution of the risks calculated by IAHP is in accordance with the available statistical findings.
