DESIGN SUPPORT METHOD FOR METAL MATERIAL, PREDICTION MODEL GENERATION METHOD, METAL MATERIAL PRODUCTION METHOD, AND DESIGN SUPPORT APPARATUS

摘要

A design support method capable of accurately obtaining predicted values, while also considering production conditions of a metal material, and of reducing the time required for design is provided. The design support method uses a calculator to support design of metal material with desired characteristics and includes searching for design conditions yielding the desired characteristics using a prediction model for predicting a characteristic value of the metal material from the design conditions, the prediction model being constructed based on past performance data associating the design conditions, including chemical composition and production conditions of the metal material, with the characteristic value. The design support method also includes presenting at least the chemical composition and production conditions among the design conditions that are searched for and correspond to the desired characteristics. The design conditions are searched for so that deviation among predicted values based on different training data sets is reduced.
