Research on accident rehearsal method based on OOFPN

This paper proposes the concept of accident rehearsal and defines its connotation based on the philosophy of the rehearsal technique. The method of accident rehearsal based on Object-Oriented Fuzzy Petri Net proposed in this paper reflects the dynamic behavior of the system and the development of the system state through state transition. It can describe the differences, the relationships and the transitions between different objects clearly, and reflect the coupling and the emergence of systems. It also can give fuzzy description of the process of incident and calculate the real value of the accident. This paper gives the definitions of OOFPN, the accident rehearsal modeling process based on OOFPN, and the reasoning algorithm to calculate the real value. A model of aircraft deviating from the runway is given using OOFPN, and the analysis of this model is provided to validate the value of this method.
