摘要
A dynamic hierarchical description method for workflow is presented. The method provides a dynamic hierarchical way to define a workflow with non-determinate or dynamic factors. With this method, the main process defined at build-time can be reified and extended by the principle of the sub-organizations at either the build-time or the run-time. To ensure the consistency and integrity of the description, a series of constraint rules are also discussed to realize seamless integration between a decomposed process and its original one. This approach supports the description of unpredictable uncertainties, the dynamic hierarchy of business process, and the dynamic modification of enterprise organizations, and all of these improve the flexibility and extendability of workflow management systems dramatically.
为支持流程中不确定性因素和动态因素的描述,提出了柔性工作流的动态层次描述方法,使得流程设计人员在流程定义阶段定义的主流程可以在任意时刻由子组织的负责人进行细化和扩充.为保证动态层次描述的正确性和完整性,讨论了动态层次描述的一系列约束规则,确保分解后的流程与原有流程实现无缝衔接.该描述方法支持对不可预知的非确定性因素的描述,支持业务流程的动态层次描述以及组织机构的变化,极大地增加了工作流管理系统的柔性和可扩展性.
