地铁系统是城市重要的基础设施，为促进经济发展和社会稳定提供重要的交通服务。由于运营中断和事故的严重后果，风险管理的主动性、针对性和有效性变得越来越重要。本文提出了一种基于网络理论和FMECA方法的地铁系统脆弱性研究新框架，其形式是利用网络理论分析网络效率，并在FMECA方法中引入风险矩阵。最后，通过实例分析验证了该框架在识别地铁系统中的脆弱关键功能模块和评估其故障模式严重度方面的有效性和可行性。最后从运营、研发、制造三个方面提出了提高地铁安全水平的组织结构。本研究将有助于对地铁运营的安全措施提供建议和意见，以减少意外故障的发生。
Subway system is a critical and fundamental urban infrastructure and provides essential transport services for promoting economic development and social stability. Due to the serious result of operation interruption and accident, it is increasingly important for risk management to be proactive, targeted, and effective. In this paper, a new framework based on network theory and FMECA method is proposed to study the vulnerability of subway system, in the form of analyzing network efficiency by network theory and risk matrix in FMECA method. Then, a case study is used to demonstrate the effectiveness and feasibility of the framework in identifying the vulnerable and critical functional module in subway system and assessing severity of its failure modes. In the end, an organizational structure is put forward from three aspects of operation, research, and manufacturer for improving the subway safety level. This research would be conducive to provide recommendations and suggestions regarding safety provisions for subway operation to reduce the occurrence of accidental failures.
