1. An anomaly handling support apparatus comprising:
a memory configured to store case performances on anomaly handling of a plurality of apparatuses; and
a hardware processor configured to perform:
identifying an anomaly cause of an abnormal apparatus in the plurality of apparatuses,
selecting an estimation model for estimating a handling method suitable for the anomaly cause from a plurality of estimation models based on a case performance of the abnormal apparatus, wherein the case performance of the abnormal apparatus associates, for the anomaly cause, a plurality of handling methods with priorities of the plurality of handling methods,
wherein selecting the estimation model comprises:
acquiring a correct handling method included in the plurality of handling methods that has restored a past anomaly due to the anomaly cause, the past anomaly having occurred before a current anomaly that is occurring due to the anomaly cause in the abnormal apparatus,
acquiring, for each of the plurality of estimation models, a number of times of handling until completion of the correct handling method based on a priority associated with a handling method corresponding to the correct handling method,
acquiring, for each of the plurality of estimation models, a handling time until completion of the correct handling method based on a sum of handling times, each of the handling times being a handling time per one time of one or more handling methods each having a priority the number of which is equal to or less than the number of the priority associated with the handling method corresponding to the correct handling method, and
selecting, based on the number of times of handling until completion of the correct handling method and the handling time until completion of the correct handling method, an estimation model for a handling method suitable for the anomaly cause from the plurality of estimation model,
estimating a handling method suitable for the anomaly cause among the plurality of handling methods based on the selected estimation model, and
outputting information indicating the estimated handling method.
