MULTI-OBJECTIVE OPTIMUM DESIGN SUPPORT DEVICE USING MATHEMATICAL PROCESS TECHNIQUE, ITS METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To perform visualization based on a mathematically processed objective function in a short time, and to enable to use it in design support, regarding a multi-objective optimum design support technology used for designing a hard disk slider form and the like.;SOLUTION: A unit 101 calculates a plurality of sets of objective functions of sample sets of input parameters. A unit 102 approximates the objective functions using a polynomial on the basis of the calculation results of the unit 101. A unit 103 calculates a logical expression indicating a logical relationship between arbitrary two or three objective functions, of the plurality of mathematically approximated objective functions as an inter-objective function logical expression by a QE method. A unit 104 displays areas that the values of the objective functions can take as usable areas according to the inter-objective function logical expression. Units 105 and 106 determine an optimum set of design parameters by limiting the sets of design parameters to corresponding sets of design parameters in the neighborhood of a Pareto boundary on the basis of the Pareto boundary of an objective function recognized from the usable areas displayed.;COPYRIGHT: (C)2009,JPO&INPIT
