Systems engineering is a multidisciplinary approach for developing solutions to complex engineering problems. The continuing increase in system complexity is demanding more rigorous and formalized systems engineering practices. In response to this demand, along with advancements in computer technology, the practice of systems engineering is undergoing a fundamental transition from a document-based approach to a model-based approach. In a model-based approach, the emphasis shifts from producing and controlling documentation about the system, to producing and controlling a coherent model of the system. Model-based systems engineering (MBSE) can help to manage complexity, while at the same time improve design quality and cycle time, improve ...
