摘　　要：工作流过程定义可以采用不同的建模方法,由于Petri网有坚实的理论基础和易于使用的图形表示,因而是一种理想的建模和分析工具,XPDL是基于XML技术的工作流过程定义语言。文中提出了六种基本的Petri网流程模块,给出了由Petri网向XPDL转换的方法以及由XPDL构造Petri网的方法。There are many modeling methods in building workflow process definition, Petri nets is more preferable modeling and analysis tools Because of its solid mathematical foundations and its simple graphic structures. XPDL is workflow process definition language based on XML. Based on putting six kind of basic Petri net process model block, the method of converting Petri net to XPDL and constructing Petri net is presented in this paper.
