组件化的变结构Petri网建模仿真方法

Modeling and Simulation Method of Changeable Structure Petri Net Based on Component

Petri网模型建立后,其结构相对固定,不易描述实际系统结构的动态变化。借鉴软件组件的设计思想,提出了组件化的变结构Petri网的描述规范、组合机制和仿真方法,实现了仿真运行中Petri网结构的动态变化。该方法增强了Petri网模型的重用性,支持层次化建模,便于实现与其他模型的集成,提高了Petri网的建模仿真能力。

The structure of Petri net model is relative stably after it is built,so it can＇t describe dynamic change of real system structure easily.Description formalness,coupling mechanism and simulation method were proposed,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 models is enhanced,integration with other models is convenience and hierarchical modeling mode is realized,and the power of modeling and simulation of Petri net is improved.
