Abstract:
1. A power consumption calculation apparatus, comprising: a work load measurement part configured to measure a work load of a job executed by an image forming apparatus and to record a measured value, at predetermined times; a management part configured to manage state transition data indicating, for a type of the image forming apparatus, power consumption and a required time for each of states of the image forming apparatus which transitions in response to an execution of each job; an acquiring part configured to acquire identification information of the image forming apparatus from the image forming apparatus connected through a network; a time calculation part configured to acquire, from the management part, the state transition data corresponding to the identification information, generating of the state transition data including comparing a first required time and a second required time for each state in at least two jobs, determining a type of state in response to whether a difference between the first required time and the second required time exceeds a predetermined value, a state being of a type of which the required time varies depending on a number of sheets to print, when the difference between the first required time and the second required time exceeds the predetermined value, and the generating of the state transition data including recording information indicating the required time of the state, which is of the type of which the required time varies, into the state transition data at the state transition detected for each of the at least two jobs, configured to calculate an aggregation of the required times of the states based on the state transition data, and configured to calculate the predetermined time based on the aggregation of the required times of the states; and a power consumption calculation part configured to calculate a power consumption amount corresponding to one job execution at each predetermined time when it is determined that the job corresponding to the work load is executed, based on the measured value and the state transition data.
