Research on Knowledge Representation for Product Design Based on Ontology

The present product design knowledge model is either limited to the certain stage of product design or limited to a specific domain of design,is not clear in the classification of product design knowledge concepts. Put forward a method of product design knowledge ontology construction in this paper and construct the knowledge representation model of product design based on ontology. Through the analysis of the knowledge concepts,attributes and the relations between the concepts produced by product design knowledge ontology,formally define and describe the knowledge resources in the domain of product design,to improve the efficiency of enterprise knowledge sharing and reuse. Taking the design knowledge representation of color sorter as an example,verify the effectiveness of the proposed knowledge representation model.
