Abstract
A design of a tire can be facilitated. An optimization apparatusinputs known design parameters of the shape, structure, and pattern of a tire, and performances thereof by an experimental data input unitand learns, as a conversion system of a neural network, a correlation between design parameters of the shape, structure, and pattern of the tire, and performances thereof. Ranges which constrain performances of the tire and design parameters of the shape, structure, and pattern of the tire, which are to be optimized, are inputted in an optimization item input unit, and the performances of the tire are predicted in an optimization calculation unitfrom the design parameters of the shape, structure, and pattern of the tire by using the optimization item and models of the calculation unit, and an objective function is optimized until the objective function which is the performances of the tire is converged. The optimized design parameters of the shape, structure, and pattern of the tire are outputted from an optimization result output unit
