【摘要】 随着我国经济及运输行业的发展,近年来高速铁路不断发展壮大,高速铁路调度指挥系统作为高速铁路列车运行的指挥中枢在保证列车的安全、高速、正点运行方面具有重要的作用,目前我国对高速铁路的安全评价主要集中在设备设施条件上,尚未建立全面的安全评价管理体系。在实际生产中,如何对高速铁路调度指挥系统采用科学合理的安全管理措施,及时辨识调度指挥作业中的各类风险因素,不断提高调度指挥作业的安全性水平是本文研究的重点。通过对高速铁路调度指挥系统及调度指挥模式研究与分析的基础上,从现场实际情况出发,以人员、设备、环境、管理四个因素作为系统安全影响因素,应用管理疏忽与危险树法(MORT)对高铁调度系统建立安全评价系统模型,并且形成各个环节的子评价体系。运用专家调查法及综合层次分析法确定各个要素的权重,通过对高铁调度指挥系统安全状况进行评价,定性MORT模型与定量分析实现了结合。最后以某一调度作业系统进行实例分析,通过分析计算证明了建立的MORT模型符合高铁调度指挥系统的安全管理实践,可以为铁路调度现场安全管理工作提供新的思路。更多还原

【Abstract】 With the development of China’s economy and transportation industry, the high-speed railway has grown in strength in recent years. High-speed railway dispatching system as a running command center of the high-speed train, it plays an important role to ensure the safety of the train and its high-speed, on-time running. This study focuses on how to use the scientific and reasonable safety measures on the high-speed railway dispatching system, identified a various types of risk factors in the dispatching operation timely, and constantly improve the safety level of the dispatching operations in the actual production. Based on the research and analysis of the high-speed railway dispatching system and its dispatching mode, this paper summarized four factors that influencing the system’s security from the actual situation of the working site: human factor, equipment factor, environmental factor, management factor; established system safety evaluation model of the high-speed railway dispatching system with MORT (Management Oversight and Risk Tree) and formated the sub-evaluation system of the various aspects of the system. The qualitative MORT model and quantitative analysis to evaluate the security situation of the high-speed railway dispatching system combined by using the expert investigation method and the Analytic Hierarchy Process that determined the weights of the various elements. Finally to analyze and calculate an example of a dispatching system, the MORT evaluation model is proved in line with the production practices of the high-speed railway dispatching system, and it also can provide new ideas for the railway dispatching management work.更多还原
