Patent ID: 8315843

Claim:
A multi-objective optimal design support device for supporting determination of an optimal set of design parameters by inputting a plurality of sets of design parameters, computing a plurality of objective functions according to a prescribed computation and applying a multi-objective optimization process to the plurality of objective functions, the multi-objective optimal design support device comprising: a processing unit that executes: a sample-set objective function computation unit for computing sets of the plurality of objective functions corresponding to a prescribed number of sample sets of the design parameters; an objective function approximation unit for mathematically approximating the objective functions using the prescribed number of the sample sets of the design parameters and the sets of the plurality of objective functions computed corresponding to the prescribed number of the sample sets of the design parameters; an inter-objective-function logical expression computation unit for computing a logical expression indicating a logical relation between arbitrary objective functions of the plurality of the mathematically approximated objective functions, as an inter-objective-function logical expression; an objective space display unit for displaying a region that values of the arbitrary objective functions can take, as a feasible region in an objective space corresponding to the arbitrary objective functions according to the inter-objective-function logical expression; and an objective space corresponding design space display unit for displaying a point or area in a design space, corresponding to arbitrary design parameters corresponding to a point or area specified by a user in a feasible region of an objective space corresponding to the arbitrary objective functions displayed by the objective space display unit; and a memory that stores said units.
