ONTOLOGY-BASED PRODUCT KNOWLEDGE REPRESENTATION FOR CONCEPTUAL DESIGN

As the globalization market formatted and complicated degree of product ceaselessly rises, it requires that the enterprise manufactures low-cost and high-quality products in a short time, it also requires that product knowledge management system supports knowledge representation, share and reuse and so on during product exploitation process. The conceptual design is the most creative stage in the design process, it devotes few but plays an important role in the performance and cost of product and the time which product come into the market. Based on analyzing the modeling process Of conceptual design, this thesis suggests an expression and semantics method which leads the ontology into knowledge. representation of the conceptual design products and adopts different expressions respectively to different information. Support the treatment of product knowledge during conceptual design according to the context. of consistent ontology structure semanteme. Meanwhile, the ontology mapping among different ontologyies may achieve the product knowledge commutation, share and reuse among collaborative partners of the product.
