The manual way of the traditional access control model caused complex access authorization and low accuracy in the hybrid organization enterprise. And the model of C-URTBAC was put forward. The model adopted the idea of the level-to-level management of users and transmission of permissions in the subject and object. It could realize semi-automatic way of authorization, so as to improve the efficiency and accuracy of authorization. And it refined the constraint classification, realizing fine-grained permissions management. Finally the model was introduced in the PLM system of some auto parts company, verifying the practicability of the model.
