Knowledge Application Techniques in Assistant Knowledge Base System for Product Design

Product design which is one of the most important stages for manufacturing is a complex activity involving a great amount of knowledge. In this paper, knowledge is divided into three types: formula knowledge, diagram knowledge, table knowledge. Based on these requirements, knowledge base is constructed. This is used to store knowledge and to support the decision-making product design. First, the knowledge representation is formally described. Then, the knowledge navigation and search strategy is detailed. A specific section is dedicated to demonstrating the knowledge application techniques according to the different knowledge types that are proposed. The proposed methods are illustrated with examples. Finally, we conclude with the presentation of application performed with the knowledge application techniques.
