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.
