Integrated modeling method oriented to multi-disciplinary collaborative development domain

To realize the information sharing of different disciplines in complex product development process, and to eliminate the obstacles of system integration, collaborative simulation and system optimization, a digital prototype construction method based on ontology meta-model was put forward. The feasibility of integrated modeling based on ontology meta-model were analyzed and a core package for meta-model by using extended model of UML was constructed. Based on the ontology theory, the concepts and their relationships in complex product collaborative development domain were analyzed, and information integration framework of multi-disciplinary collaborative domain was established. The digital prototype model which covered product information, development method information and development process information was built based on ontology meta-model. The abstract evaluation, granularity decomposition and multi-disciplinary coordination of complex product in development process were supported by proposed models. The active phased array radar was used to illustrate the models.
