Mixing ratio determination device, mixing ratio determination method, and program

Abstract

In this blending ratio determination device, a learning means learns using compatibility scores between materials of known compatibility, and generates a prediction model that predicts the compatibility scores between materials of unknown compatibility. A compatibility prediction means uses the prediction model to generate compatibility score information including compatibility scores between the materials of unknown compatibility. A problem generation means generates an optimization problem that includes compatibility scores between a plurality of materials to be blended in an objective function. A blending ratio determination means determines the blending ratio of the plurality of materials by solving the optimization problem.
