This example SysML model demonstrates the Model of Models (MOM) methodology with a focus on aircraft and their systems, subsystems, and components. An advanced MBSE approach, MOM maximizes reuse, modularity, and traceability. The model encompasses the conceptual, logical, and physical levels, illustrating how to apply the Object-Oriented Systems Engineering Methodology (OOSEM) in a modular and recursive package structure. It showcases how to manage and integrate various aircraft components efficiently, leveraging MagicDraw-specific features like acronyms. This model serves as an invaluable reference for organizations looking to optimize their digital engineering processes through the MOM methodology, enhancing their capability to develop and maintain complex aircraft systems.
