摘　　要：针对电子政务工作流系统的特点,在基本RBAC模型的基础上,引入了组织机构图和额外授权的概念,提出了改进的RBAC模型,并给出模型各要素的形式化描述.模型根据组织机构图划分出原子权限,借助拓扑集合完成角色的设置.在实现用户-角色和角色-权限的指派过程中,考虑了角色的继承,并给出模型实现过程中应该注意的原则.模型具有实现快捷和管理方便的特点,可以加快工作流管理系统的开发进程.并通过开发的办公自动化系统实例加以证明.For the E-governance workflow system, an improved RBAC model is proposed. The model includes concepts of organization chart and extra permission assignment and presents a formalized description of key elements. The model marks off primitive permissions according to organization chart. It implements the setup of roles by the topological collection. During the process of assigning the user-role and role-permission, the model gives attentive principles and concerns the inheritance of roles. The main advantage of the model is its rapidness and convenience for implementation. It can quicken the developing process of workflow management system. At last, an example of OA is given to prove the model.
