ABSTRACT
This chapter describes model-based systems engineering (MBSE) that is an approach to applying systems engineering principles, tools, and activities with a focus on developing electronic models that are architected to be integrated throughout the systems engineering life cycle as well as from high levels to more detailed levels of the models and from single elements to the integrated system. MBSE requires a change in thinking from a modeling approach based on documents, such as requirements, specifications, drawings, test cases, to one based on integrated models that are architected to demonstrate traceability between the elements of the traditional documents used in systems engineering design and development. Some MBSE tools have embedded meta models that maintain the elements, their relationships, and behaviors, while other MBSE tools allow the user to create their own models, elements, and relationships, which can lead to lack of consistency and standardization.
