Important Progress in Multifactor Optimization Briefly Noting the History of the Development of Method of Orthogonal Array

? Multifactor optimizatien is an important subject of science that accumulated numerous and jumbled contents and had various solutions. Since there has method of orthogonal array,great changes have been obtained for working benefit and optimizing efficiency.This paper briefly introduces and notes the developmental process of the method and theory of orthogonal array and its position and character from authors opinions and practices.The whole paper includes six sections: in the section one gives the problems, in the section two roughly gives a classification of the optimization subjects (includes onefactor subjects),in the section three gives eight explanations from the theoretical relationships of the subjects of science,in the section four introduces the developmental progress of the orthogonal method,in the section five recommends the orthogonal method as the principal method of multifactor optimization for social uses, finally in the section six proposes the works that ought to be continuously pushed forward.
