【摘要】 针对目前工作流管理系统在描述能力和动态修改上存在的不足,提出一种基于构件的柔性变更策略.该策略引入新的建模元素和动态变更的体系结构,从时间和工作流组成两个角度对工作流的动态变更进行了分类,详细阐述了工作流的组合策略、修改方法和移交策略;最后论述了这种策略的优越性、可行性和正确性.更多还原

【Abstract】 In order to solve the problem of poor description ability and dynamic modification existed in existing workflow management system,a new strategy of dynamic workflow flexible change based on component is put forward.The proposed strategy introduces the new modeling elements and architectonics of dynamic change,and classifies the dynamic change from the point view of the time and composition of workflow,and discusses the composing strategy and modifying method and hand-over strategy in detail.Finally,the advantage,feasibility and correctness of this method are discussed.更多还原
