By studying the key event paths of Probabilistic Event Structure Graphs (PESGs), a key e- vent path analysis approach for integrated system models is proposed. According to rules concluded from integrated system architecture descriptions, the corresponding PESGs are constructed from the CPN mod- els. Then the definitions of cycle event paths, sequence event paths and key event paths are given. Where after, based on the statistic results after the simulation of CPN models, key event paths are found out by the sensitive analysis approach. This approach focuses on the logic structures of CPN models, which is re- liable and could be the basis of structured analysis for discrete event systems. An example of radar model is given to characterize the application of this approach, and the results are worthy of trust.
