Through multi-case study and structured description method, theattributes of information alienation of emergency are extracted. On this basis,a stochastic Petri net model of emergency information evolution is developedwith random Petri net. Further, the equivalent markov chain model isconstructed according to the isomorphism relationship between random Petri netand markov chain. Finally, the incident of Limin irradiation factory in Henanprovince is taken as an example to simulate the different status of eventinformation alienation, and to analyze the equilibrium and change rule. Inaddition, some countermeasures and suggestions has been put forward.
