基于扩展UML活动图的工作流模型研究

Research of workflow modeling based on extended UML activity diagrams

针对目前工作流管理系统在表达能力和适应性方面存在的问题,在给出三层工作流过程元模型的基础上,提出了基于扩展UML活动图的工作流建模方法,扩展了多实例、条件路由和协调节点等建模元素,描述了扩展建模元素的定义、路由结构和建模规则。应用模型实例表明,此方法增强了模型描述能力,在模型适应性和柔性方面具有明显的优势。

In order to solve the problems of poor description ability and adaptation existed in present workflow management system.Firstly,provided the three layers meta-model of workflow processing,put forward a new workflow modeling method based on extended UML activity diagrams.The proposed method extended the traditional activity model and introduced the new modeling elements definition,route configuration and modeling rules,such as multiple instance node,constrain route node and coordinating node.Research results...
