摘要
面对越发激烈的竞争环境,当今企业的业务流程种类越来越多,流程的执行过程也充满了各种不确定因素,传统的PDM的流程管理一般不能根据实际情况进行动态的改变。针对这个问题,介绍了动态工作流的特点,讨论了基于角色的动态工作流建模技术,以及基于角色状态的动态访问控制方法,并设计了支持模型进行动态演化的算法。
With the more and more keen competition environment, there are more and more kinds of the business process have been presented. The execution of the process becomes unpredictable. So the traditional Workflow Manage- ment System generally can not change quickly to adapt the new environment well. In order to solve this problem, this pa- per introduces the characteristic of the dynamic workflow, It analyzed the dynamic modeling technology based on role and analyzed the dynamicaccessing and controlling methods based on roles states independently. Furthermore it designed an al- gorithm supporting dynamic evolution of model.
