基于服务模板的动态工作流建模及实现

摘要

针对当前工作流管理系统难以应对企业组织流程变更的问题,基于服务模板技术,提出了一种动态工作流建模方法.首先以服务模板的形式建立动态工作流模型,完成整个业务流程的预定义和对应组织服务的绑定.在此基础上完成该模型的动态操作算法,实现工作流运行过程中对流程变更的发现与自动更新.最后以一个企业工作流项目实例来验证模型的可行性和正确性.实例证明,该模型可以满足企业动态变更组织流程的需求.%In order to solve the problem of hardly dealing with modification of the changes of the enterprise organizational processes using existing workflow management systems, a dynamic workflow modeling approach is proposed based on service template technology. Firstly, a dynamic workflow model is established using service template to pre-define the business processes and bind corresponding organizational services. Furthermore, the algorithms for dynamic operations are proposed to implement the discovery and the adaptively updating of process changes during the running time of the workflow. Finally, an enterprise workflow project is used as a case study to verify the correctness and feasibility of the workflow model. The result shows that the model can meet the enterprise requirements of dynamic changing of the organizational processes.
