【摘要】 为了满足Petri网理论的应用研究的需要,首先给出了层次对象广义随机Petri网模型的定义,并运用面向对象方法设计和开发了基于层次对象广义随机Petri网的可视化建模和仿真工具软件,详细介绍了该软件工具的设计方法,包括功能结构图、网模型对象类图和符合可扩展标记语言规范的中性文件格式存储模型数据结构。最后通过实例说明了该工具应用的有效性。更多还原

【Abstract】 To apply Petri net theory, the definition of Hierarchical Object General Stochastic Petri nets (HOGSPN) was given. Using the object-oriented method, the HOGSPN-based visual modeling and simulation tool software was also developed. The function structure of the tool and the object class diagram of net-model were discussed in detail. For data exchange, a file format based on eXtensible Markup Language (XML) was used to restore the information of model structure and data. Finally, an example was illuminated to show the practical application of this tool software.更多还原
