摘要:

工作流模型的建立是工作流管理系统中非常重要的一步，关系着工作流管理系统实施的成败。文中首先分析了基于IPO图的有向图工作流模型，并在其基础上运用面向对象的思想提出了基于活动节点和有向连接弧的有向图模型。接着分析了这种模型的特点，结合XML技术给出了该模型的XML文件定义，通过具体的实例说明了该种模型的可扩展性和可维护性，可以有效解决一些流程描述中的难点，并给出了流程描述难点如联合审批和回退机制的支持和解决方案。最后结合了电子文件的申请浏览流程的例子说明了该模型定义在实际流程的中的有效运用

Abstract:

The workflow model is a very important part of workflow management system. It can bring success to it or not. Analyzes the the directed - graph model based on IPO graph, then brings out the research of the directed - graph model based on activities and directed ares using the object - oriented method. Then gives the traits of this model. An XML file is given according to the definition of this modal. Explain the expansibility and maintenance of this model by some material examples. It can resolve some difficulties effectively in the flow description. Also overcome the difficult questions such as united checking and returning mechanism during the course of the running of workflow. At last,an example of the applying view coure of the electronic files is introduced to explain the concrete application of this model
