本体驱动的复杂产品设计模型集成

Aiming at the problems of data separation, semantic inconsistency and low efficiency of semantic integration among requirement models, architecture models and traceability models in complex product design process an ontology-based models integration method was proposed. Firstly, the ontology framework of requirement, architecture and traceability models was established by combining the model embodiment and application scenario. Then the Basic Formal Ontology (BFO) was used to integrate the three domain ontologies. forming a general model integration ontology framework for Model-based Systems Engineering (MBSE) application environment. Based on the ontology framework, the bidirectional automatic generation of models and ontology was realized. Taking the intelligent electric vehicle system as a case, the effectiveness of the proposed method was verified.
