Composition amount determining method and device for functional mixture

摘要

A device and a method for determining amounts of each of composition constituents necessary for giving a functional mixture functionality, without actual creation of the functional mixture, by varying the amounts in accordance with correlation coefficients between each of the composition constituents of previously obtained functional mixtures. The Mahalanobis distance for the amounts of N composition constituents, the Mahalanobis distance for the amounts of N-1 composition constituents from which one of the constituents is excluded, and the difference therebetween are calculated. The amount of composition constituent whose exclusion corresponds to the largest such difference is varied and the Mahalanobis distance is calculated again. Amounts of composition constituents for which the Mahalanobis distance is a minimum are selected as the amounts of the composition constituents for the functional mixture.
