摘　　要：为了实现电力营销系统用户对公共服务权限和责任区权限的同步控制,提出电力营销系统用户访问权限的鲁棒自适应同步控制方法。以角色访问控制为基础,基于鲁棒k-means算法划分用户责任区,计算责任区内用户的可信度;依据计算结果判断对应权限内角色的权限等级,以此可访问权限对应范围内的信息和资源,同时可拥有相应的操作权限;在制定初始访问策略集后,通过自适应蚁群算法的求解访问策略以获取最佳策略。测试结果表明,提出的方法具备良好的鲁棒性,优化效果在85%以上,可有效降低加权复杂度,能够实时监测用户信用度的变化,计算用户的信任度,实现公共服务权限和责任区权限的同步控制。In order to realize the synchronous control of users'public service authority and responsibility area authority in electric power marketing system,a robust adaptive synchronous control method is proposed.Based on the role access control,the user responsibility area is divided based on the robust k-means algorithm,the credibility of the users in the responsibility area is calculated,and the permission level of the role within the corresponding permission is judged according to the calculation results,so as to access the information and resources within the corresponding scope of the permission.The method has the corresponding operation permission,and formulates the initial access policy set.The optimal access policy is obtained by solving the access policy by adaptive ant colony algorithm.The test results show that the method has good robustness,the optimization effect is more than 85%,and the weighting complexity can be effectively reduced.It can monitor the change of users'credit in real time,calculate users'trust,and realize the synchronous control of public service authority and responsibility area authority.
