Abstract: To satisfy the requirements for quick acquisition, organization and reuse of product knowledge in agile product customized design, the method of product knowledge management based on design repository was proposed. Design repository was responsible for organizing various kinds of knowledge from different data sources and setting up a subject-oriented multi-dimensional design knowledge model. Users and designers could input inquiries into Case-Based Reasoning (CBR) systems. Then On-Line Analysis and Processing (OLAP) drilled down and found the similar cases. Knowledge reduction techniques were adopted to reduce the retrieved similar cases output from OLAP, which improved CBR. Machine Learning could capture the cases adaptation knowledge to complement design repository. Finally, the proposed approach was demonstrated by a real application of tied bill machine.

Key words: knowledge management, design repository, case-based reasoning
