OPTIMAL VALUE SEEKING DEVICE, METHOD, RECORDING MEDIUM, AND COMPUTER PROGRAM PRODUCT

摘要

This invention provides an optimum value search apparatus, method, recording medium, and computer program product used in designing, analyzing, or testing a device having a plurality of factors that have effects on a characteristic. In this method, an orthogonal array is generated by setting level values obtained from the initial values of the factors to the coordinates of a two-dimensional table including a matrix of the characteristics and the factors (S31 - S33). From the characteristics on the orthogonal array, characteristic values obtained on the basis of combinations of the level values of the factors of a single characteristic are grasped (S34). A combination having a most excellent characteristic value is selected (S35). The level values of the factors in the characteristic corresponding to the selected combination are reset in the orthogonal array (S37). After resetting in step S37, the processes in steps S34 and S35 are repeatedly executed to search for an optimum value as a most excellent one of the characteristic values (S34 - S38).
