为综合评价高速公路系统的服务状况,在分析高速公路系统的服务状况影响因素的基础上,提出了高速公路系统的服务状况多层次模糊综合评价系统方法。首先选取能够反映高速公路系统的服务状况的评价指标26项,建立这些评价指标的量化评分方法。对于定量指标,采用4类12种评分函数描述方法;对于定性指标,采用专家打分法进行量化评分。然后采用改进的层次分析方法确定评价指标的权重,提出模糊综合评价模型。最后通过应用实例分析,验证了高速公路服务状况综合评价方法在评价高速公路服务状况方面的可行性和有效性,它的分析结果将为高速公路运营管理部门提供可靠的分析、管理和决策的依据,对改善高速公路运营管理水平,提高高速公路服务水平和运行质量,充分发挥高速公路的服务效益有重要意义。
In order to comprehensively evaluate the service status of expressway system, the article analyzes the influencing factors of service status of expressway system, and proposes a multi-level fuzzy comprehensive evaluation system method for service status of expressway system. Firstly, we select 26 evaluation indexes which can reflect the service condition of expressway system, and establish the quantitative evaluation method of these evaluation indexes. For quantitative indicators, four kinds of 12 kinds of scoring functions were used to describe the method; for qualitative indicators, scoring was scored by expert scoring method. Then using the improved analytic hierarchy process to determine the weight of the evaluation index and put forward the fuzzy comprehensive evaluation model. Finally, the application example is given to verify the feasibility and effectiveness of the comprehensive evaluation method of expressway service status in evaluating the service condition of expressway. The results of the analysis will provide reliable basis for analysis, management and decision-making of expressway operation and management department It is of great significance to improve the operation and management level of the expressway, improve the service level and operation quality of the expressway and give full play to the service efficiency of the expressway.
