【摘要】 随着企业竞争的加剧和政府对提高工作效率的迫切需要,工作流的柔性问题成为研究的热点．为了解决工作流的动态性及柔性问题,提出了一种基于状态控制的解决方案。重点分析了如何通过角色流、控制流、时间流和动作流的相互配合来实现基于状态的动态访问控制。并提出了工作流模型进行动态演化的算法,使动态变化的工作流程能与原流程实现无缝衔接。该建模方法在我们研发的工作流系统中得到了实现。最后指出了动态柔性工作流系统建模方法的不足和发展方向。更多还原

【Abstract】 As the increasing enterprise competitions and demands for government efficiency, the research on the flexibility of workflow has become an academic hotspot. To deal with dynamic characteristic and flexibility of workflow, a solution based on state control is put forward. How to realize dynamic access control based on state through the collaboration among role-flow, control-flow, time-flow and action-flow is analyzed in particular. Then an evolvement algorithm to support the dynamic change of workflow model is proposed to realize seamless integration between dynamic workflow and original workflow. The modeling method is implemented in the workflow systems researched and developed by us. In the end, this paper indicates the deficiency and developing trends of dynamic flexible workflow systems modeling method.更多还原
