Abstract: A prediction device for predicting a thermodynamic equilibrium state of a target material, includes a processor, and a memory storing program instructions that cause the processor to generate training data including inputs related to predetermined design conditions and outputs related to the thermodynamic equilibrium state that may occur based on the predetermined design conditions, for a model that outputs target variables related to the thermodynamic equilibrium state based on input explanatory variables related to design conditions of the target material, perform machine learning using the training data so that an input-output relation of the model approaches an input-output relation of the training data, set explanatory variables used to predict the thermodynamic equilibrium state of the target material, and output predictive target variables, being predicted results of the thermodynamic equilibrium state, from the model, based on the explanatory variables input into the model on which the machine learning has been performed.

Abstract: A material design device derives the optimal solution for a design condition satisfying a desired material property. A design condition setting unit for setting a specified range of a design condition of a material to be designed. A comprehensive prediction point generation unit generates a plurality of comprehensive prediction points within the specified range set by the design condition setting unit. A design condition-material property table stores data sets in which each point of the comprehensive prediction points is associated with a material property value calculated by inputting the comprehensive prediction points generated by the comprehensive prediction point generation unit, to a learned model. A required property setting unit sets a specified range of a required property of the material. A design condition extraction unit extracts, from the design condition-material property table, a data set satisfying the required property set by the required property setting unit.
