Abstract:
A computer program product which enables a computer system to support the design of a structure, comprising:a storage medium;storing means provided in the storage medium for storing different kinds of orthogonal arrays, the different kinds of orthogonal arrays being utilized to arrange data regarding design variables and levels which are set in accordance with objects to be analyzed;means for causing the computer system to arrange the data regarding the design variables in each row and column of an orthogonal array selected from the storing means on the basis of the design variables and levels of an object to be analyzed, with reference to level numbers of the orthogonal array;means for causing the computer system to output the results of data arrangement in the orthogonal array;means for causing the computer system to receive the results of structural analysis which is executed on the basis of the data arranged in the orthogonal array;means for causing the computer system to execute an analysis of variance on data of characteristic values which are obtained on the basis of the results of the structural analysis, said characteristic values indicating characteristics of the object to be analyzed; andmeans for causing the computer system to extract design variables and degree components which have high effectivity for the characteristic values on the basis of the results of the analysis of variance and to generate estimation expressions in relation to the characteristic values on the basis of the extracted design variables and degree components by use of orthogonal functions.
