摘　　要：快速路网络系统的服务水平评价是一个多目标综合评价问题,文中从快速路系统目标出发,以系统管理者为评价主体,利用层次分析法(AHP)和模糊综合评价方法,建立了快速路系统服务水平二级综合评价模型,确定了评价指标体系,采用单准则层次分析法AHP确定了评价指标的权重,建立了各个评价指标的隶属函数,选择了适宜的模糊评价模型,提出了根据应用目的确定评价结果的方法,最后进行了算例分析.文中提出的方法可应用于运营阶段快速路系统的服务水平评价.The evaluation of service level of expressway network system is a multi-objective comprehensive evaluation problem. In this paper, by taking the supervisors of expressway system as the appraiser and the expressway system as the objective, a two-level comprehensive evaluation model for service level evaluation is established based on the analytic hierarchy process （AHP） and the fuzzy comprehensive evaluation （FCE） method. Then, the evaluation indices are determined and the weights of the indices are obtained by means of the single-rule AHP method. Moreover, the membership functions of the indices are developed, a suitable fuzzy evaluation model is selected, and a method to determine the evaluation results according to the evaluation aims is put forward. An numerical example indicates that the proposed method is suitable for the evaluation of service level of expressway system in operation.
