In an optimization apparatus 30, a known compositional ratios and the like, and mechanical behaviors thereof are inputted by an experimental data input unit 40 and a learning is conducted in a non-linear calculation unit 32 in order to establish a corresponding relation between compositional ratios of multi-component materials and the like, and mechanical behaviors thereof as a conversion system based on a neural network. Compositional ratios and the like are inputted in an optimization item input unit 42, and a mechanical behaviors are predicted in an optimization calculation unit 34 from compositional ratios and the like of the multi-component materials using the optimization item and the conversion system of the calculation unit 32, and an objective function is optimized until the objective function, expressing the mechanical behaviors are converged.

1. A design method for a multi-component material comprising the steps of:(a) determining a conversion system using learning in which a non-linear correspondence between compositional ratios of multi-component materials composed of a plurality of components as inputs and mechanical behaviors of the multi-component materials as outputs is established; (b) determining an objective function expressing said mechanical behaviors and setting a constraint condition constraining the allowable range of at least one of said mechanical behaviors and said compositional ratios of the multi-component materials; and (c) determining a compositional ratio of the multi-component materials which gives an optimal solution of an objective function by using said objective function and said constraint condition on the basis of the conversion system determined in said step (a) to design the multi-component materials on the basis of the compositional ratio which gives the optimal solution of the objective function.
