Abstract
A corrosion rate estimation device for estimating a corrosion rate of a metal disposed in a predetermined environment includes an input unit that inputs water component information including information such as water content (time), temperature, conductivity, soil type, and the like, a corrosion rate estimation model configured to receive the water component information related to a water component contained in the predetermined environment as an input, and estimate the corrosion rate of the metal disposed in the predetermined environment from the water component information, and an output unit that outputs the estimated corrosion rate of the metal to the outside. The corrosion rate estimation model is generated using, for example, a machine learning algorithm such as a random forest, a neural network, or RNN (LSTM).
