Reliability Modelling of Dynamic Random System Based on Petri Net

This article uses Petri Nets' ability to describe dynamic systems and applies Petri Nets to the field of mechanical system reliability analysis. The method of expressing fault events and their logical relations based on Petri net theory is studied, and the method of applying Petri net to the reliability modelling of complex dynamic system is discussed. Through the simulation of the model, the reliability of the real-time expert system is analysed, and the relationship curve between the system reliability and the real-time limit and heuristic error is given.
