A Design Knowledge Representation and Reuse Method Based on Ontology and Knowledge Component

At present, the design knowledge can't be reused effectively and this leads to the long design cycle and repetitive works in product design. To solve this problem, this paper researched on a design knowledge reuse method based on knowledge component. By analyzing the representation demand of design knowledge, we studied the knowledge expression and reuse method which contains the ontology and knowledge component. We use ontology to integrate and represent design knowledge and use knowledge component to realize the rapid reuse of knowledge. In addition, we build the mapping between knowledge component and the ontology. We make sure the security of knowledge by a shared mechanism. Finally, we use the air inlet design process as an example to show that this method is meaningful.
