Abstract
Stochastic Petri Nets (SPN) approach is used to model emergency response process of metro emergency in order to analyze the performance of emergency response process of metro emergency. With the method of “top down,” we establish the basic models of each stage of metro emergency, then according to the actual rescue process with each stage mode of public places and transitions to construct a SPN model of the emergency response process. According to the possible state set of SPN mode, an isomorphic Markov Chain is developed for measuring and evaluating the performance of emergency response process of metro emergency, and the efficacious of the model is justified through the case of Beijing metro emergency plan response process.
