支持复杂事件处理的业务流程建模研究

摘要

现有的流程建模语言缺少对复杂事件的支持.通过对BPMN进行扩展,提出一种事件的分层方法来表达业务过程中的基本事件和复杂事件.在此基础上进一步提出CE-BPM建模方法,并给出其形式化定义和图形化表示,增加了复杂事件和复杂事件处理网关的图形表示.最后通过实例来说明用BPMN建模时遇到的问题以及如何用CE-BPM建模解决问题的.%Existing process modeling languages lack the support for complex events. By extending BPMN, an events hierarchical model is proposed to express basic events and complex events. Further, a modeling method-E-BPM is put forward, and its formal definition and graphical representation are provided, where complex events and complex event handling gateway graphics are added. Finally, an example of online shops is given to explain on how to use CE-BPM to solve the problems may be met when use BPMN.
