Abstract: For multi-type and large-scale of Manufacturing industry chain downstream enterprise group,to solve the control problem of industrial chain collaboration of cloud computing services platform access,the multi-level system of multi-type cooperative control mechanism was put forward.Based on cloud service model of SaaS/PaaS,the platform access control scheme with multi-level and divided system was given from the industrial chain business collaboration and access control.By using the collaborative relationship of each system-level,a multi-dimensional Boolean matrix was constructed.The semantic relationship was used to transform Boolean relation matrix into multi-level system control model of complex network,and the simulation for this model was carried.The practical application scheme and results were also given.This network model improved the traditional Role-Based Access Control (RBAC) static control mode,and had a better stability and scalability.It provided a better theoretical support for solving cloud services platform access control problems of large-scale enterprise group in the process of diverse role level authorization and dynamic changes of permissions system.

摘要： 面向制造业产业链上中下游大规模多类型企业群,针对产业链协同云计算服务平台的访问控制问题,提出多类型协同的多层级体系控制机制。基于SaaS/PaaS的云服务模式,从云服务平台产业链的业务协作与访问控制协同出发,给出多层次、分体系的平台访问控制方案。利用各体系层次的关联关系,构建了多维关系布尔矩阵。利用语义关系将布尔关系矩阵转化为多层级体系复杂网络控制模型,并对网络模型进行了仿真实现,给出了模型的实际应用方案及效果。该网络模型改进了传统的基于角色的访问控制静态控制模式,且具有较好的稳定性与扩展性,为解决大规模企业群在角色层次授权多样化、权限体系动态变化过程中的云服务平台访问控制问题,提供了较好的理论支撑。
