Based on how to construct the work environment of collaborative product design under manufacturing supply chain, three elements including task, department and role were introduced into collaborative model, which were consisted of the TD-RBAC model and jointly decided the authorization that subject could access to the object. Further, the authorization strategy and control strategy of TD-RBAC model was analyzed, which solved the access control problem faced with suppliers, customers and internal users of core enterprise under the environment of collaborative product design, and also achieved the access control in organizational levels among the members of collaborative product design. On this basis, the ontology was introduced to construct the knowledge concept hierarchy to achieve the knowledge-based access control management. Combining the four levels of knowledge concept hierarchy with TD-RBAC model, the knowledge sharing model in collaborative product design was established using UML.
