Abstract: Random characteristics can be analyzed by stochastic Petri net,but delay time and delay cost problem cannot be computed by stochastic Petri net.In order to solve above problem,a stochastic Petri net model based on delay characteristics was proposed.The delay time and delay cost were analyzed using the model proposed in this paper.The serial and parallel simplification method about delay time and delay cost were studied.Finally,an example of the capital airport shows that the method can represent the emergency rescue time and cost characteristics better than traditional one.

Key words: Delay characteristics,Stochastic Petri nets,Emergence rescue
