METHOD FOR DETERMINING A PRODUCT COMPOSITION FOR A CHEMICAL MIXTURE PRODUCT

The invention relates to a method for ascertaining a product composition for a mixed chemical product, a series of feature values, which numerically describe feature values in each case of a descriptor of the particular mixed product, being provided, for each first product composition of a plurality of first product compositions, in the case of a plurality of first product compositions for a particular mixed chemical product, each first product composition being characterised by a numerical product distribution for describing the proportions of components of the first product composition, the series of feature values for each mixed product being mapped by first bijective mapping onto a series of mapped feature values, a series of test feature values, which numerically describe in each case a behaviour property of the particular mixed product, being provided for a plurality of second product compositions for a particular mixed chemical product, the series of test feature values for each mixed product being mapped by second bijective mapping onto a series of mapped test feature values, at least the first or the second mapping including a modification, each series of mapped test feature values of a second product composition being assigned to a series of modified feature values of a first product composition, a correlation matrix being ascertained by multivariate analysis of the associated series, a target requirement profile being predefined for describing at last one behaviour property of a target mixed product and a target descriptor profile for describing descriptors of a target product composition being determined on the basis of the target requirement profile and the correlation matrix.
