Modeling and Simulation Method of Component Based Petri Net

The structure of Petri net model is relative fixed after it is built, so it cant describe dynamic change behavior of real system structure easily. Description formalness, coupling mechanism and simulation method were presented, the dynamic change of Petri net structure in simulation run was realized based on the idea of software component design. The reuse capability of Petri net model is enhanced, integration with other models is convenience and hierarchical modeling mode is realized, and the capability of modeling and simulation of Petri net is improved.
