Product development knowledge management and reuse of enterprises to maintain a competitive advantage in the era of knowledge economy has important significance. Of the Task Force carried out based on design knowledge reuse (reusable design) theory, method and technology research funded by the National Natural Science Foundation of China. Product knowledge management (PKM) prototype system of combined participate in multiple projects, research support reusable design knowledge management methods and implementation techniques, developed versatility, visualization, and easy expansion and discusses the problem of the application of the system. First, the paper in a brief introduction to the the reusable design theory based on A three tables (information table, decision tables, and control tables) knowledge representation. The basis of the overall design of the product knowledge management system, the PKM architecture, processes and functions of knowledge processing structure, discussed the integration of the the PKM system with other systems. Then, the paper focuses on product knowledge management methods and implementation techniques. To increase the versatility of the product knowledge management system, the authors propose a method based on the product knowledge of the data dictionary definition of visualization, the method by the decomposition of the three knowledge table constructed to describe the basic structure of the data dictionary, and developers to the the data dictionary the visual expansion to add new types of knowledge. The principle of this method, knowledge visualization definition process and implementation techniques. Focused on product design information in knowledge acquisition, access methods and decision rules extracted from the decision table. In knowledge organization, mainly using the mixed product structure and the type of knowledge-based organization, the method and its implementation techniques discussed. Fast retrieval of knowledge is to improve the basis of reusable design efficiency, design knowledge retrieval structure in order to achieve adaptive the designer knowledge retrieval habits, the major methods and technology are discussed. In addition, the paper discussed PKM product design technology. Discussed on the basis of analysis of the the PKM use of the product design process, based on the STEP product characteristics knowledge acquisition method to study the expression of knowledge in the PKM. The realization of the product structure extraction technology as well as knowledge of part feature classification method based on a hybrid product design knowledge organization. To the three gearbox output shaft design, for example, discusses the design knowledge retrieval and application problems. Finally, the introduction of part of the development of product knowledge management system iPKM running instance, a summary of the full text, and the research and application of PKM outlook.
