摘　　要：为解决城市轨道交通运营安全评价指标缺乏时效性和部分安全评价模型忽略评价等级的模糊界限等问题,重新构建城市轨道交通线路的运营安全评价指标体系,包括员工对传染性疾病防控措施的执行力度、相关单位的配合程度、防控设备的完备程度等新指标;其次运用基于离差最小化的最优最劣法(BWM)和反熵权法对各指标进行组合赋权;然后应用可拓云确定城市轨道交通线路运营安全评价等级;最后以上海地铁17号线为例进行实例分析。结果表明:上海地铁17号线运营安全评价各指标的各级云关联度低于0.5且置信度高于0.99,其中,人员因素、线路因素、管理因素的置信度均为1,仅设备因素的置信度为0.998;结合每个二级指标的灵敏度值分析,得出车站运营设备的可靠性对线路实际运营安全影响最大;在实际运营中,乘客对车站传染性疾病防控的配合程度越高,对综合评价的提升也越大;该评价指标体系和评价模型能够准确地反映城市轨道交通线路运营安全水平,且更加适用于目前城市轨道交通线路的运营情况。In order to solve the problems of lack of timeliness in the evaluation indicators of urban rail transit operation safety and some safety evaluation models ignoring the fuzzy boundaries of evaluation levels,a new evaluation index system for the operation safety of urban rail transit lines was reconstructed,including new indicators such as the implementation of infectious disease prevention and control measures by employees,the degree of cooperation between relevant units,and the completeness of prevention and control equipment.Secondly,the combination weighting of various indicators was carried out using the Best Worst Method(BWM)based on the minimization of dispersion and the anti-entropy weighting method.Then,the extension cloud was applied to determine the safety evaluation level of urban rail transit line operation.Finally,take Shanghai Metro Line 17 as an example for analysis.The results indicate that the comprehensive cloud correlation degrees of various indicators for the operational safety assessment of Shanghai Metro Line 17 are below 0.5,with a confidence level exceeding 0.99,among which the confidence levels for personnel factors,line factors,and management factors are all 1.This suggests that the employed indicator system and evaluation model are closely aligned with the current operational conditions of urban rail transit,accurately reflecting the safety levels of urban rail transit operations.Further analysis of the sensitivity of indicator values reveals that the reliability of station operational equipment has the most significant impact on the actual operational safety of the line.In practical operations,the degree of passenger cooperation in preventing and controlling infectious diseases at stations has the greatest potential to improve the indicator.It can help subway companies establish a more scientific and effective safety evaluation system to ensure the safety of daily line operations.
