Anomaly prediction apparatus, anomaly prediction system, anomaly prediction method, and computer readable medium

An anomaly prediction method comprising:

• regarding a target part that a target device includes as deteriorated at a subject point in time and the target part at the subject point in time as a target deteriorated part,
• to predict a point in time an anomaly will occur in the target device, in a case where there is a dissimilarity between a relative position of a driving portion corresponding to the target deteriorated part with respect to a different part and a relative position of a driving portion corresponding to the target part of a case where the target part is not deteriorated with respect to the different part, and the anomaly is estimated to occur in the target device by the target deteriorated part becoming more deteriorated and a distance between the driving portion corresponding to the target part and the different part reaching an anomalous distance, based on a residual distance that is a difference between the distance between the driving portion corresponding to the target deteriorated part and the different part, and the anomalous distance, by a computer.

A non-transitory computer readable medium storing an anomaly prediction program that causes an anomaly prediction apparatus that is a computer to execute:

• a deterioration prediction process, regarding a target part that a target device includes as deteriorated at a subject point in time and the target part at the subject point in time as a target deteriorated part,
• to predict a point in time an anomaly will occur in the target device, in a case where there is a dissimilarity between a relative position of a driving portion corresponding to the target deteriorated part with respect to a different part and a relative position of a driving portion corresponding to the target part of a case where the target part is not deteriorated with respect to the different part, and the anomaly is estimated to occur in the target device by the target deteriorated part becoming more deteriorated and a distance between the driving portion corresponding to the target part and the different part reaching an anomalous distance, based on a residual distance that is a difference between the distance between the driving portion corresponding to the target deteriorated part and the different part, and the anomalous distance.
