WEAR STATE PREDICTION METHOD, WEAR STATE PREDICTION DEVICE AND WEAR STATE PREDICTION PROGRAM

A wear state prediction device (10) is provided with a model generation unit (124) which generates a model for predicting a wear state as an objective variable by using a predetermined algorithm in which air temperature data on an aircraft (31) acquired in advance is set as an explanatory variable, and a wear state prediction unit (133) which inputs air temperature data to the model generated by the model generation unit (124) and predicts the wear state.
