A Multi-factor Coupling Event Chain Model Based on Petri Nets
Accident is always the result of a variety of influence factors which are in dynamic operational processes and mutual coupling.Because there is still lack of technical approaches supporting the study of accident analysis by the view of multi factor coupling and accidents dynamic development, a new model of multi-factor coupling event chain based on Petri Nets is presented in this paper.By analyzing the dynamic multi-factor coupling relationship of process,we can get a course of conduct in a different state of the evolution of different paths.The model has the Petri Nets characteristics, and can effectively represent the system evolution from normal to danger.As the multi-factor coupling relationship is complex, this paper proposed single coupling,correlative coupling (including Seriescoupling,Parallel coupling,Series-parallel coupling,Ring coupling),Control coupling, and other models.Finally, an event chain model of the aircraft spiral approach process is given by using the method, and the analysis of this model is provided to validate correctness of this technique.
