基于混合Petri网的图形建模仿真系统

A Hybrid Petri Net-based Modeling and Simulating System with GUI

将VC++的面向对象思想引入混合Petri网建模、仿真技术的研究和开发,给出了面向对象的混合Petri网软件结构,研究了Petri网的创建方法,讨论了Petri网的系统维护以及Petri网的存储结构等关键问题。在此基础上,设计了基于图形界面的混合Petri网建模仿真软件。对于具体实例,给出了该软件以人机交互方式建立、编辑、分析混合Petri网模型的过程。

The object-orientedconcept in C＋＋ was introduced into the research and development of Hybrid Petri Nets-based modeling and simulation techniques. The architecture of objected-oriented hybrid Petri nets software was given, and the methodology for the building of Petri nets system was investegated. Some key problems such as maintenance of the system and the storage structure of Petri nets were solved. Based upon these approaches an HPN modeling and simulating software package with a GUI was developed. Using the software a hybrid Petri net model for an illustrating example has been established, edited and analyzed in a friendly graphical user interface.
