Ontology-based knowledge integration of collaborative design for aviation complex products

To solve the problem of knowledge integration difficulty and achieve design knowledge sharing and reuse for the designers, an ontology-based knowledge integration approach of collaborative design for aviation complex products was proposed in this study. In order to realize the ontology integration, ontology modeling of product collaborative design knowledge was conducted firstly based on analysis of composition of collaborative design knowledge. On this basis, an ontology-based knowledge integration model of collaborative design for aviation complex products was constructed. The model transformed the problems of design knowledge integration into knowledge ontology integration problems, and through the establishment of global ontology and local ontology to implement knowledge integration between heterogeneous systems. Finally, a specific application was presented to illustrate the feasibility and validity of the knowledge integration method.
