企业在面临电子商务的挑战中,越来越重视业务过程重组.建立一种合理的流程模型是成功开展BPR(business process re-engineering)的关键.这样的模型应该可以集成企业许多业务相关的信息并且是可被系统解释执行的.在参考WfMC(workflow management coalition)元模型基础上建立了一种基于ECA(event-condition-action)规则和活动分解的工作流模型.ECA规则反映活动之间的执行依赖关系,通过重写办法把ECA模型变为触发器形式的TA(trig
While facing the challenge of e-commerce, the enterprises pay more attention to the business process re-engineering (BPR). A reasonable model to describe the business process is the key point to BPR sucess. Such a model should integrate all related business information and should be enacted by a system. Referencing on the WfMC (workflow management coalition) meta-model, a workflow model based on ECA rules and business activity decomposition is presented. The ECA rules imply the execution dependencies among the zctivities.Using rewriting techniques,the ECA(event-condition-action)model is transformed to Trigger-Action model to make the interpreation more efficient.Rewriting the event to the occurrence time of the event makes the event expression have more expressive semantics.Activity decomposition model can support the hierarchical project management.
