Abstract
A design support method includes an orthogonal array allocation step for arranging data regarding design variables and levels in columns and rows of an orthogonal array, a structural analysis step for carrying out structural analysis for data in each row of the orthogonal array, an analysis-of-variance step for carrying out an analysis of variance in accordance with the result of the structural analysis step, an estimation expression generation step for extracting those design variables and degree components which have high effectivity for characteristic values indicative of the properties of the object of analysis, in accordance with the analysis of variance, and generating estimation expressions based on orthogonal functions in accordance with the design variables and degree components, and an optimization process for making a target optimization calculation by using a mathematical optimization method. Reanalysis, evaluation of dispersion, and evaluation of reliability of structure, can be carried out by using the estimation expressions.
