工作流系统中一种基于任务-角色的委托模型

A Task-role-based Delegation Model for Workflow System

随着工作流技术的广泛应用,工作流系统中的委托机制也越来越重要.针对工作流环境中任务是委托的主体等特点,提出适用于工作流系统中一种基于任务-角色的委托模型DE-TRBAC,并对该模型的元素定义,委托关系,委托条件,委托实施过程及委托撤销等方面作了详细描述,通过该模型建立相对完善的委托机制.

With the wide application of workflow technology,delegation mechanisms is more and more important in workflow system.In the light of features of workflow environment that task is the main part on delegation,this paper presents a task-role-based delegation model,called DE-TRBAC,which has done a detailed description on defining the elements of the model,delegation relationship,delegation condition,delegation process from implement action to revoking.The purpose is for establishing relatively complete delegation mechanism.
