With respect to input data having the spread of errors or the like, "a suiting method" is to obtain a suiting function, which exist within a region of this spread, and which is highly robust. A suiting region (between an upper bound function M+(xi) and a lower bound function M-(xi)) is set based on the input data with the spread of errors. An inequality system is established with respect to the suiting region and the suiting function having undetermined parameters. A distance from a boundary of a solution region of the parameter values, corresponding to a boundary of the suiting region, is set, and a suiting function f(x) which has the parameter values maximizing the distance, is found. A broken line exhibits a suiting function f'(x) having low robustness, and a solid line exhibits a most-robust suiting function f(x) obtained from an application of this invention.
