基于Petri网的工作流模型研究与设计

Research and Design of Workflow Model Based on Petri-net

Petri网是一种适合于描述异步并发现象的系统模型,它既有严格的数学定义,又有直观的图形表示。工作流技术作为实现企业过程集成的有效手段,广泛应用于各种场合。本文在简要介绍了Petri网、工作流与工作流模型的理论后,对公文流转中的发文工作流进行了基于Petri网的模型设计。

Petri-net is a kind of system model that is propitious to describe asynchronous and eoneurrent phenomena, it has not only strict math definition, but also direct graphic express. Workflow technology is an effective measure realizing enterprise process integration and widely applied in many occasions. This artide simply presents the theory of Petri-net, workflow and workflow model, and designs model of sendingfile workflow in official document circulation based on Petri-net.
