Guidelines for systematic functional decomposition in model-based systems engineering

The increasing complexity in today’s products require an ever more systematic product development process in which the use of model-based systems engineering (MBSE) plays an increasingly decisive role, especially against the background of cross-disciplinary collaboration. Having evaluated the actual state of the art, many companies still have true difficulties when modeling the functional architecture with the help of actual approaches. Thus, a new procedure with concrete guiding rules and control criteria to strategically define and decompose functions for the two perspectives a greenfield and brownfield environment is theoretically introduced and partly applied to a practical example.
