Device Management System That Improves Accuracy of Alert Notification, Device Management Apparatus, and Device Management Method

摘要

A device management system includes an electronic device, a device management apparatus, a value acquiring circuit, a time calculation circuit, and an alert notification circuit. The alert notification circuit notifies an alert indicating that an adjustment-limit time calculated by the time calculation circuit is close. The time calculation circuit calculates a predicted value of the use amount value where the adjusting value reaches the limit based on a log of combinations of the use amount values and the adjusting values, the use amount value and the adjusting value being acquired by the value acquiring circuit, and the time calculation circuit calculates the time at which the use amount value reaches the calculated predicted value based on a log of the use amount values as the adjustment-limit time.
