In order to further prove up the accident causation mechanism of complex system and provide effective tactics for safety control,on the basis of describing the idiographic application steps of the cognition-constraint model built by the authors before and system risk entropy definition,an Arena simulation model was built for the risk entropy dynamic transmission in a simplified accident causation network.Dynamic data on risk entropy in the network,and the data on risk entropy treatment process in key nodes were obtained by Arena simulation.Influences of node immunity probability on network risk entropy treatment ability were studied.Research results show that the key node confirmed according to static network structure does not conform to reality,the identification of the key causation node must consider both of the static network structure and the dynamic risk transmission process.
