PROBLEM TO BE SOLVED: To determine the quantity of each constituent for imparting functional characteristics to a functional mixture in such a manner as to get close to the coefficient of correlation between constituents of a previously obtained functional mixture without actually preparing a functional mixture. SOLUTION: The Mahalanobis' distance D<2> as to the quantities of N constituents and the Mahalanobis' distance Dk<2> as to the quantities of constituents excluding one constituent, i.e., (N-1) constituents, are obtained by arithmetic operations (112, 116), corresponding to the quantity of the excluded constituent. The deviationΔDk=D<2> -Dk<2> is obtained by an arithmetic operation (118), the quantities of excluded constituents are varied to give a maximum deviation (126), the Mahalanobis' distance D<2> as to the quantities of N constituents, including the varied quantities of constituents, is obtained by an arithmetic operation again, and the quantities of constituents when the Mahalanobis' distance is minimum are determined as the composition of a functional mixture (132).
