基于组合赋权方法的城轨线路运营安全评价

Evaluation of Urban Rail Transit Line Operational Safety Based on the Combination Weighting Method

摘要:

摘要：在对城市轨道交通线路运营安全进行详细分析的基础上，系统地构建了城市轨道交通线路运营安全评价指标体系，并对各指标的含义及计算方法进行了研究。同时，对城市轨道交通线路运营安全等级进行了划分，采用层次分析法和熵值法组合赋权的方法来评价影响城市轨道交通线路运营安全的各项指标，符合系统的完整性，最后以北京市地铁4号线为例对其运营安全进行综合评价，验证了该方法的合理性和可靠性，为城市轨道交通运营安全决策与安全控制措施提供了理论依据。

Abstract: On the basis of analyzing urban rail transit line operational safety，the line operational safety evaluation index system of urban rail transit is established, the meanings and calculation methods of indexes are studied and the line operating safety grade of urban rail transit is delimited. The line operational safety indexes of urban rail transit is evaluated with the method of analytic hierarchy process and entropy method combination weights, which accords with system integrity. Beijing metro line 4 is evaluated as an example to verify the rationality and reliability of this method. And it provides theoretical basis for operational safety decision-making and safety control measures of urban rail transit.
