中文摘要：

为了提高铁路应急救援效率，将铁路应急预案与应急救援有机地关联起来，需要对应急救援流程进行更加深入的分析及系统性建模。通过随机Petri网对铁路应急救援流程进行建模并对系统性能进行定量分析，提出提高铁路应急救援效率的方法。

英文摘要：

In order to improve the efficiency of railway emergency rescue and correlate the railway emergency plan with emergency rescue closely, it was needed to analyze the process of emergency rescue deeply and carry on the systematic modeling, Based on the stochastic Petri Net, it was carded on the dynamic modeling for the process of railway emergency rescue and analyzed the System performance quantitatively, It could get the methods of improving the efficiency of railway emergency rescue.
