摘要
针对工作流管理系统的实现复杂性及模型可靠性的验证问题,提出了一种结合工作流网和ECA规则来创建工作流管理系统的方法。这种基于ECA规则的工作流描述和执行机制较好地实现了工作流网模型的语义描述和控制的统一。通过建立基于ECA规则的工作流描述表,将ECA规则引入到工作流路由机制中,灵活地控制了工作流的流程。通过事件触发和消息处理机制,工作流描述表处理可以被实际系统加以执行和控制。
Due to complexity of implementing workflow management system and problems of soundness verification of workflow model, a combination method of workflow nets and ECA （event-condition-action） rule that constructs a workflow management system is brought forward. The semantics description and control of workflow nets are unified by the workflow description and executive mechanism based on ECA rule. Through establishing workflow description table based on ECA rule, the flow of the workflow is expediently controlled by adding ECA rules into workflow route mechanism. Through event trigger and message handle mechanisms, workflow description table can be executed and controlled by actually system.
