【摘要】 针对现有工作流管理系统缺乏一定的柔性及适应能力等问题,从工作流系统的建模阶段和运行阶段这两个层面来展开讨论.采用黑盒子建模思想描述局部具有动态特征的工作流系统.着重阐述了基于状态的动态访问控制方式,给出了在工作流执行过程中,对工作流程进行动态修改及将修改后的工作流模型进行动态演化的算法.更多还原

【Abstract】 This paper discusses the problems of poor flexibility and adaptability existing in workflow management system from the modeling phase and the operational phase.Using black-box model to describe workflow system with local dynamic to illustrate the state-based dynamic access control.The algorithm that depict the method of modifying workflow and solve modified workflow is put forward.更多还原
