Abstract:
A method and apparatus for producing a design for a system (2) that comprises a plurality of subsystems (4, 6) is provided. Criteria to be satisfied by the system (2) are identified. For each subsystem (4, 6), further criteria that are to be satisfied by that subsystem (4, 6) are determined and a parametric model (8, 16) is then determined. These comprise inputs (10, 18) and outputs (14, 22) that are dependent on the inputs (10, 18). A systems engineering model (100) comprising, as inputs, parametric model inputs (10, 18) is then determined. System model outputs (28) are dependent on the system model inputs. Groups consisting of some of the system model inputs are formed and an optimization process is performed, for each group, to determine inputs that optimize the system model outputs (28). A set of inputs that optimize the system model outputs (28) provides a design for the system.
