Abstract:
A computer system that determines a set of parameter values of a physical system exhibiting physical characteristics, comprising:an input device that inputs physical characteristics;a memory device that stores a suiting region corresponding to an allowable range of said physical characteristics;a setting device that sets said suiting region, input via said input device, in said memory device; anda processor/controller that executes a calculation to find a suiting function, contained in said suiting region, by solving simultaneous inequalities, said processor/controller including a first setting system that sets said suitng function as a family of functions with parameters corresponding to the parameters of said physical system, a second setting system that sets a distance from a boundary of a solution region of the parameters of said suiting function, corresponding to a boundary of said suiting region, and a solution system that solves said siutaneous inequalities so that said distance is maximized thereby determining a robust set of parameter values of said physical system.
