1. A power consumption control system, comprising:
at least one processor configured to execute at least one software element; and
at least one memory device storing instructions which, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
predicting at least one of a traffic amount or a number of accommodated persons in a next unit period of time;
identifying, for the predicted traffic amount or number of accommodated persons in the next unit period of time, a power state for the at least one processor to reach a given performance index value when executing the at least one software element, wherein identifying the power state is based on correspondence data that indicates, for the at least one software element and a traffic amount or a number of accommodated persons in a next unit period of time, correspondence between a plurality of power states and performance index values; and
operating the at least one processor to execute the at least one software element in the identified power state,
wherein the identifying comprises identifying, based on the correspondence data indicating a correspondence between a traffic amount or a number of accommodated persons in a next unit period of time and a value of an average processing time for each of the plurality of power states, a power state having the lowest power consumption when operating as a first power state among power states for reaching a given average processing time in the predicted traffic amount or number of accommodated persons in the next unit period of time,
wherein the identifying comprises identifying, based on the correspondence data indicating a correspondence between a traffic amount or a number of accommodated persons in a next unit period of time and a value of an average packet discard rate for each of the plurality of power states, a power state having the lowest power consumption when operating as a second power state among power states for reaching a given average packet discard rate in the predicted traffic amount or number of accommodated persons in the next unit period of time, and
wherein the operating comprises operating the at least one processor to execute the at least one software element in the first power state or the second power state being a power state having higher power consumption.
