摘　　要：在应用传统的层次分析法(analytic hierarchy process,AHP)进行风险评估时,存在难以保证判断矩阵的一致性要求且精度不高等问题,文章对原有的模糊互补矩阵构造过程进行改进,并通过约束规划解法得出权重后迭代来提高计算精度,以此建立新的模糊层次分析模型;以合肥金寨路地铁站为算例,应用该方法对其进行了详细的风险等级评估,得出目标层和各准则层的风险等级,评估结果与现场实际相符合。When applying the traditional analytic hierarchy process(AHP)for risk assessment,it is difficult to guarantee the consistency of the judgment matrix and the accuracy is not high enough.In this paper,the original fuzzy complementary matrix construction process was improved,the weight was figured out through the constraint programming solution and iterated to improve the calculation accuracy,then a new fuzzy hierarchical analysis model was established.Taking the Jinzhai Road Subway Station in Hefei City as an example,the method was applied to evaluating the risk level in detail,and the risk level of the target layer and each criterion layer was figured out.The results of the evaluation are consistent with the actual situation.
