摘要:
［目的］上海轨道交通信号系统存在体量大、型号复杂、运行年限不一致等情况，其整体状态评估存在过程繁琐、效率低下、运算复杂等问题。对此，有必要提出一种基于AHP(层次分析法)的城市轨道交通信号系统状态评估方法。［方法］采用AHP构造判断矩阵、计算特征向量，得到子系统及性能的权重。基于不同子系统、不同性能的评分标准，结合子系统及性能的权重得到整体状态评估分值。以具体线路为例，采用该方法对信号系统状态进行评估。［结果及结论］基于该评估方法，对上海轨道交通11号线信号系统整系统状态进行评估，评估分数为71.81分，整体状态良好，应加强日常维护维修保障。针对评分较低的车载列车控制子系统及数据通信子系统，可开展一些专题研究与专项整治。该评估结果及应对方针已被相关维护部门所采用。
Abstracts:
［Objective］ Shanghai rail transit signaling system faces challenges including large scale, complex model variations, and inconsistent operational lifespans. Current holistic status assessment methods suffer from cumbersome processes, low efficiency, and complex calculations. Therefore, it is necessary to propose an AHP (analytic hierarchy process)-based status assessment method for urban rail transit signaling systems. ［Method］ AHP is employed to construct judgment matrices and calculate eigenvectors, obtaining subsystem weights and performance indicators. Based on scoring criteria for different subsystems and performance metrics, combined with their respective weights, an overall status assessment score is derived. This method is applied to assess the signaling system status of a specific rail transit line. ［Result & Conclusion］ Using this assessment method, the entire signaling system of Shanghai Rail Transit Line 11 is evaluated, achieving a score of 71.81 points, indicating its good overall condition. However, daily maintenance and repair safeguards should be strengthened. For the lower-scoring on-board train control subsystem and data communication subsystem, thematic studies and targeted improvements are recommended. The assessment results and response measures have been adopted by relevant maintenance departments.
