摘　　要：介绍了一般Petri网及工作流网的基本定义,在基本的工作流网系统定义的基础上,引入面向对象技术及分层技术,提出了一种面向对象的工作流网的模型,以提高模型的可读性和重用性,实现流程的分层建模,降低建模复杂度。通过一个具体实例阐述了如何建立扩展工作流网模型,并通过简化技术和可达树分析方法,验证了模型的活性。The general Petri net and the workflow net basic definition are introduced. In the basic workflow net system definition foundation, the object-oriented technology and lamination technology is introduced into, the object-oriented workflow net model is proposed to enhanced the readability of the model and realize the flow laminatim modelling, modeling complex is reduced. How to establishe the expansion work drift net model is expounded by an example, and through reachability tree method and the reduction technology, the model activeness is confirmed.
