Model-based systems engineering which plays a fundamental role in dealing with system complexity becomes a hot topic in the systems engineering field, and it is a guarantee to promote engineering capabilities in the future. This article begins with the concept and evolution history of model-based systems engineering, then analyzes the application of MBSE through domestic cases as well as overseas. Finally, difficulties and countermeasures for China's future model-based systems engineering development are discussed.
