Abstract
A method of predicting a corrosion loss of a metal material, the method including: inputting a prediction request point including a use period of the metal material for which a corrosion loss is desired to be predicted and second environmental parameters indicating a use environment of the metal material in the use period; calculating a similarity degree between first environmental parameters in corrosion loss data and the second environmental parameters in the prediction request point; dimensionally reducing the first environmental parameters in the corrosion loss data to a latent variable taking the similarity degree into consideration; and predicting a corrosion loss of the metal material for the prediction request point based on a prediction expression constructed using the latent variable and the similarity degree.
