Abstract: To achieve the management, integration and sharing of the product information involved in the activities of manufacturing enterprise, such as research, development, production and management, a generic product information management system based on workflow is established. Based on four manufacturing workflow element models, an integrated product information management system is developed by using electronic warehouse technology and the file’s checking in/out operation. Practice shows that the system can achieve the integration and sharing of the product information between different departments within the manufacturing enterprise, and support product lifecycle’s information management as well.
