Product Development Integration Techniques and System Based on CAx and Knowledge Management

Knowledge has become a key economic resource of enterprise and to become even only source of competitive advantage. With the structure of the product more and more complicated, function more and more incline to integration and compounding, modern product design is one base on knowledge. Knowledge-based integrated information system, to support knowledge management and technology innovation, is the development trends of information integration system. The integration information of computer aided technology (CAx) was analysed. A data structure of integration product model base on relation database was introduced. Knowledge-based integration system for product development was drawn out. It is a system base on product data management system and knowledge management system. This system framework used synthetically information technology and advanced manufacture technique, and realized product speedy and innovation design

Performance Evaluation Method and Algorithm of Knowledge Management for Product Innovation Design

This paper presents a discussion of knowledge management performance evaluation index and evaluation methods for product innovation. The content of knowledge management and the flow of knowledge in product innovation process are analyzed. According to the purpose of performance evaluation and combined with the characteristics of product innovation, the knowledge management performance index for product innovation is established, and the specific evaluation method and algorithm are described. The fuzzy comprehensive evaluation process is discussed
