北京轨道交通燕房线为“综合科技示范线”，示范国产化全自动运行(fully automatic operation，FAO)技术的应用。全自动运行系统是基于现代计算机、通信、控制和系统集成等技术实现列车运行全过程自动化的新一代城市轨道交通系统。燕房线全自动运行系统是国际公共交通联会(UITP)定义的自动化等级为4级(GOA4)的系统。由于采用了很多新技术，燕房线在工程建设期间探索出一套适用于全自动运行系统的风险管理方式。从工程安全评估角度介绍全自动运行系统工程核心设备系统的安全以及风险管理，从而确保工程建设满足可靠性(reliability)、可用性(availability)、可维护性(maintainability)和安全性(safety)(RAMS)要求。国内其他全自动运行系统线路建设期间的风险管理也可借鉴燕房线核心设备系统独立安全评估的经验。
The Beijing Yanfang Line was proposed as a “comprehensive technical demonstration line” to pilot fully automatically operation (FAO) technology. FAO is a new generation of modern urban guided transportation system that is based on the technology of computer, communications, and control and system integration. The FAO of the Yanfang Line was designed as per requirements of the level-4 of grade of automation (GOA4), which is defined by the International Association of Public Transport (UITP). Because many new technologies and applications have been used, new risk management approaches were explored to be established during the Yanfang Line project. This paper introduced independent safety assessment and risk management core equipment system of the FAO system from an independent safety assessor’s viewpoint. This is the first time that the Reliability, Availability, Maintainability and Safety (RAMS) requirements of the project was assessed. The experience of risk management and the independent safety assessment gained from the Yanfang Line can be referenced or used by other FAO projects.
