In the past decades of development, domestic companies have adopted traditional document-based systems engineering methods for product design. However, how to accurately express or interact with other existing systems has become insurmountable for companies in forward design.

Especially in recent years, with the in-depth development of technologies such as big data and Internet of Things, products are becoming more and more electrified and intelligent, making product forms more and more complex, product design concepts are becoming more and more ambiguous, and it is difficult for companies to establish standards System engineering research and development environment.

As a design method based on understanding the behavior of the system, Model-Based Systems Engineering (MBSE) was formally proposed by the International Committee of Systems Engineering, and it has received widespread attention in the engineering field, setting off an upsurge in learning MBSE.

Through the application of MBSE, enterprises can quickly deal with system requirements, function and architecture definitions, allocation and tracking links and other issues, and promptly guide the later design, implementation, synthesis and verification processes, and effectively analyze the development cycle and development cycle caused by changes in requirements. Changes in cost make the product design process manageable, reproducible and reusable.

What is MBSE? The International Society for Systems Engineering (INCOSE) believes that it is the formal application of modeling methods in systems engineering to support activities related to requirements, design, analysis, verification, and validation throughout the life cycle of the system. It can be seen from the definition that MBSE is an evolution of the traditional document-based system engineering work model. It strives to use a multi-perspective system model as a bridge to link cross-disciplinary/domain models to achieve cross-disciplinary/domain model traceability.

Drive the engineering activities of various stages in the life cycle of large-scale complex systems, and finally realize the collection, capture and refinement of data, information and knowledge in a model-driven method.

The characteristics of MBSE are different from concepts such as model-based design (MBD) and computer-aided design (CAD). MBSE does not focus on solving specific subject design problems, but emphasizes modeling for the system engineering process, integrating system requirements and system analysis The analysis elements involved in the process of, system design, system verification, etc. are modeled and organically connected to reproduce system demonstration and design ideas, and maintain the consistency and traceability of system information throughout the life cycle.

Therefore, in terms of the connotation of the MBSE concept, MBSE is not an out-of-the-box general method. In the process of specific application of MBSE, it is necessary to combine the modeling concept with the actual business for in-depth customized design.
