As the product data and management information of the institutes are increasing rapidly, huge amount of electronic data are produced in the process of scientific research and production, which makes the information retrieval, control, sharing and management very difficult. Through the construction of the Production Development System(PDS) with the core of product development, a web-based digital product R&D management system can be established in the office of scientific research online and the unification of the product, centralized management and information sharing with the support of network environment and database can be realized. A detailed analysis and research of the PDS system is conducted from the different levels of basic needs, the overall objective, the system functional framework, the application examples and the effects of the PDS.
