“…Representation, acquisition, organization, and retrieval of design knowledge are the main contents of knowledge reuse research. Firstly, the classification, representation, and storage of design knowledge are studied, and then, the reuse of design knowledge is realized according to the new design constraints [16]. e design knowledge reuse technology for integrated product rapid development is studied, and an integrated product development system scheme based on design knowledge reuse is proposed on the basis of in-depth research on key technologies such as design knowledge representation, management, and reuse [17].…”
