摘要
实现工作流技术的关键环节在于工作流的概念模型,而其中的过程建模又是构建工作流管理系统的基础,因此,对建立工作流模型的研究和应用比较多。近几年,随着业务流程建模、工作流概念的出现以及Petri网技术的发展,Petri网也被用于工作流模型的建立。该文在介绍工作流模型和Petri网基本概念的基础上,介绍工作流的四种基本流程结构,并以工作流的四种基本流程结构为出发点,给出了如何把它们映射成符合工作流网定义的模型的一种方法。
Conceptual model is the key to develop its workflow technology and the process of building model is the basic of establishing workflow management system,so research and application about workflow model is so much. In recent years,with establishment of business process model and Petri net technology development,Petric net is also used in building workflow model. This article introduces workflow and the basic concept of Petri net. Introduced the four basic of process workflow structure,and workflow processes of the four basic structure as the starting point,given a way of how they map into compliance with the definition of WF-net model.
