摘要: 为更加准确地评价轨道交通车辆系统安全现状,解决单一方法评价的模糊性问题,提出一种基于系统动力学(SD)和云模型的评价方法。首先,依据问卷调研和现行相关标准,提出轨道交通车辆系统安全评价指标体系;其次,采用主成分分析法和SD模型,分析指标体系各层指标的权重;然后,构建轨道交通车辆系统安全评价云模型,评价轨道交通车辆系统及其子系统的安全现状;最后,以大连地铁1号线为例,验证评价模型的有效性。结果表明:驱动系统、车辆安全设备和车辆监控系统是轨道交通车辆系统的重要子系统;安全评价云模型能直观地评价车辆系统的安全性,便于轨道交通车辆系统安全管理。

Abstract: In order to evaluate safety status of rail transit vehicle systems more accurately and solve ambiguity of single method evaluation, an evaluation method based on SD and cloud model is proposed. Firstly, a safety evaluation index system was put forward on the basis of questionnaire survey and current relevant standards. Secondly, principal component analysis and SD model were used to analyze weights of each index. Then, a cloud model for safety evaluation of rail transit vehicle system was established to assess safety status of the system and its subsystems. Finally, model verification was conducted with Dalian Metro Line 1 as an example. The results show that drive system, vehicle safety equipment and vehicle monitoring system constitute important subsystems of rail transit vehicle system. Safety evaluation cloud model can intuitively assess system safety and facilitate its safety management.

Key words: rail transit vehicle system, indicator system, system dynamics (SD), cloud model, safety evaluation
