Research on ontology-based knowledge modeling of design for complex product

Abstract

To solve the problems of the design knowledge sharing and reuse difficulty in the process of complex product design, an ontology-based knowledge modeling method of complicated product design was proposed. A complex product design work model was established by analyzing the characteristics of complex product design firstly, and an ontology construction framework for complex product design was also put forward. At the research background of auto products design, the knowledge modeling process of complex product design based on ontology modeling theory was studied by utilizing the classification and description method of thinking. On this basis, a knowledge ontology model for complex products design was constructed. Finally, an application case was presented to illustrate the feasibility and validity of the knowledge modeling method.
