摘　　要：为了解决面向协作的柔性工作流在动态环境下兼顾柔性和安全性的问题,针对协同环境的特点,在分级授权管理的基础上引入团队的概念,通过将基于角色的静态授权和基于任务的动态控制相结合,实现面向协作的柔性工作流的授权与访问控制,并对由柔性和分工协作而产生的不同层次潜在的约束冲突进行基于任务的职责分离分析,以更好地解决动态环境下柔性工作流的信息安全与访问控制问题。With gradual improvement of collaborative manufacturing mode,the played an important role for the adjustment of organizational structure and business process reengineering.How to balance the To solve the problem that collaboration oriented flexible workflow should combine flexibility and security in dynamic environment,according to the characteristics of collaborative,the concept of team was introduced based on the hierarchical authorization management to realize the combination of role-based static authorization and task-based dynamic control,and a novel access control model was proposed for cooperation-oriented flexible workflow.As for the potential conflict of constraints at different levels due to the flexibility and cooperation,task-based separation of duty was provided,so as to better solve the problem of information security and access control for flexible workflow in dynamic environment.
