摘要

为了科学把握城市轨道交通系统关键设备运行状态,保障城市轨道交通设备运行安全,研究提出了城市轨道交通关键设备识别与运行状态评价体系。首先,通过人员访谈和现场踏勘检查的方式对深圳地铁集团有限公司、厦门轨道交通集团有限公司等企业进行了实地调研,建立了多层次城市轨道交通系统设备评价体系;其次,以设备发生事故的频次程度(Frequency, F)、发生事故的严重程度(Severity, S)和运营单位对风险设备的管控程度(Control, C)作为评估指标,采用层次分析法(Analytic Hierarchy Process, AHP)确定指标权重,建立了AHP-模糊FSC综合评价模型,识别城市轨道交通关键设备;再次,借鉴欧洲RAMS(Reliability, Availability, Maintainability, Safety)标准,以可用性指标判断设备运行状态,并将其划分为健康、良好、危险以及严重4个等级。最后,以深圳地铁1号线通信信号系统为例进行验证。结果表明,该研究成果可以识别城市轨道交通关键设备和判断设备运行状态,为城市轨道交通关键设备运行状态评价提供了一种切实可行的操作方法。

Abstract

In order to scientifically grasp the operation state of key equipment in urban rail transit system and ensure the safety of urban rail transit equipment, a key equipment identification and operation status evaluation system of urban rail transit was proposed. Firstly, through investigating Shenzhen Metro Group Co., Ltd., Xiamen Rail Transit Group Co., Ltd. and other enterprises, a multi-level equipment evaluation system for urban rail transit system was established. Secondly, taking the frequency degree of equipment accidents, the severity degree of accidents and control degree of risk equipment by the operation unit as evaluation indexes, using Analytic Hierarchy Process to determine index weight, an AHP-based fuzzy FSC comprehensive evaluation model was established to identify the key equipment of urban rail transit. Thirdly, referring to relevant European RAMS standard, the running state of equipment was judged by availability index, and was divided into four grades: healthy, good, dangerous and serious. Finally, taking communication and signal system of Shenzhen Metro line 1 as an example, the evaluation model was verified. The results show that the research results can identify the key equipment of urban rail transit and judge the operation state of the equipment, which provides a practical and feasible method for evaluating the operation state of the key equipment of urban rail transit.
