摘　　要：在基于工作流的应用系统中,业务过程的不可预见性往往会要求工作流能够适应不断改变的业务环境,而传统的工作流技术通常对业务动态可变的支持度不够。本文在传统工作流建模的基础上通过扩展工作流元模型给出了一个支持动态修改的工作流体系结构,并在jBPM的基础上拓展,对应用中出现的流程迁移、动态路由、组织关系变更等动态修改的情况进行了分析,制定了相应的变更规则,提出了解决方法,在一定程度上提高了工作流系统的动态适应性。In the application systems based on workflow, the unpredictability of the business process requires the workflow should be adjusted to the changing business environment, which has not been supported by the traditional workflow technologies . By following the traditional workflow modeling means and expanding the workflow meta-model, a workflow construction is presented. It extends the jBPM and analyzes some kinds of dynamic evolutions such as the transfer of the flow, dynamic adjustment of the transition, and the changing of the organization model, institutes some changing rules and puts forward the handling methods, improves the dynamic adaptation of workflow systems.
