复杂时空约束条件下基于角色的转授权模型研究

摘要

Aiming at the problems of complex temporal constraints in delegation process , which include the time , system resources and conflict events , the detailed characteristics and forms are analyzed ,and the realization algorithm about the role-based delegation model under the complex temporal constraints is given .Through several e-government system applications and tests ,a better performance of the proposed method is shown .%　　针对信息系统转授权处理过程中存在的复杂时空约束问题，即时限约束、系统资源约束和互斥约束展开研究。在详细分析了各自的特征以及表现形式的基础上，具体讨论了在复杂时空约束条件下基于角色的转授权模型的处理方法和详细的算法流程。多个电子政务系统的实际应用和检验表明研究成果具有较好的性能。
