摘　　要：根据分布式环境下工作流应用的需求,在基于角色授权的基础上补充了基于用户资格和特征的授权模式,提出了分布式环境下基于工作流域层次结构的用户授权管理模型,并综合利用了推结构和拉结构技术,给出了用户授权指派的高效算法.According to the application requirement of workflow in distributed environments, an authorization pattern based on user qualifications and characteristics in addition to the authorization pattern based on role is supplemented. A hierarchic model of user authorization administration based on workflow domain in distributed environments is proposed, and the efficient algorithms for user authorization assignment using both push architecture and pull architecture are proposed.
