  • Publication number: 20190287008
    Abstract: A management apparatus for managing one or more devices includes circuitry to: acquire information indicating a use history of a device for each predetermined period; calculate, based on the acquired information indicating the use history, a predicted value indicating operation timing at which an operation is performed on the device; and output, based on the predicted value, an output value for the predetermined period. When an output value that is output for an (N?1)-th time is greater than a threshold, the circuitry outputs, as an N-th-time output value, the predicted value that is calculated for an N-th time. When the output value that is output for the (N?1)-th time is less than or equal to the threshold, the circuitry outputs, as the N-th-time output value, a value that is smaller than or equal to the output value that is output for the (N?1)-th time.
