Model-based systems engineering employs the method of model expression throughout the whole system's life cycle to describe requirements, design, analysis, verification and validation. It has rapidly found applications in such as aviation, aerospace, shipbuilding, and other related engineering fields thanks to the advantages of unambiguity, modularization, reusability and traceability. This paper summarizes the relevant elements of the model-based system engineering, including methodology, modeling language, and tools. An exploration on the function modeling of aero engine sub systems is described.
