%X 针对目前高速铁路列车运行控制过程安全研究多以单个子系统为研究对象，缺乏系统整体性且忽略了系统间的风险传递特性的问题，基于复杂系统脆性理论和有色Petri网及其仿真工具，以系统间的信息传递过程为切入点，建立一个包括计算机联锁子系统、列控子系统和调度指挥子系统的三级模型；从脆性源、脆性传播路径、系统崩溃标准3个特征出发阐述高速铁路列车运行控制过程的结构脆性；基于有色Petri网仿真工具CPN Tools中的I/O文件流和C#建立状态空间结构脆性分析平台.研究结果表明： 行车许可请求子模型MAR（movement authority request）中变迁间的相关性平均值为56.72%，CTCS-3级列控子模型CTCS3（Chinese train control system-3）内的变迁间的相关性平均值为9.56%，可根据结构脆性指标的不同制定差别化的日常安全管理策略.<br>： The majority of previous studies on train control process safety focused on individual subsystems; this approach lacks wholeness and ignores the risk-sharing problem introduced by information transfer between different subsystems. Here, a three-level system, namely a computer-based interlocking system, train control system, and centralized train control system, was modelled from the perspective of information passing between subsystems, and the structural brittleness of the train control process was analysed. First, the structural brittleness of the high-speed railway train control process was stated according to brittleness sources, the brittleness propagation path, and the system crash standard. Then, a simulation platform was set up for system brittleness analysis based on the I/O file stream in CPN Tools and C# programming language, and a simulation example was designed. The results show that the average correlation between sub-transitions in the movement authority request submodel is 56.72%, and that in the CTCS-3 submodel is 9.56%; these results provide a reference for the differentiated typical safety management strategy
