The basic elements of model-based design for space missions have existed for almost a decade, awaiting an opportunity to implement them in the same place at the same time. In early design phases, combinations of models, concurrent engineering methods, and scenario-driven design have been used for several years with results that have exceeded even optimistic expectations; but the goal of extending these methods to later phases of design has been more elusive. JPL's model-based engineering design (MBED) initiative provides opportunity to reach that goal. It enables advanced systems engineering practice through a series of integrated, increasingly detailed models that provide continuity from architectural concept through detailed design. It extends current capability for rapid conceptual design, allowing thorough exploration of design tradespaces and selection of an optimal design point with associated cost and rationale; and it provides seamless connection to subsystem models and detailed design tool suites. We review the goals and status of MBED and show the expected interconnectivity between conceptual and detailed design.
