Abstract

A time range setting unit (110) sets an operation startable time point at which an operation can be started and a target operation end time point which is the latest time point among time points at which the operation is to be ended, with respect to each of plural power demanding objects (20). A necessary operation time setting unit (120) sets a necessary operation time with respect to each of the plural power demanding objects (20). A shape information acquisition unit (130) acquires shape information from a schedule management device (40). The shape information indicates an assumed shape of a transition line that represents transition in the amount of supplied power in a target period. A demand transition setting unit (140) sets power demand transition information indicating transition in an electric energy demand in the target period so that the necessary operation time is obtained and so that the transition in the electric energy demand generated by the plural power demanding objects (20) being operated accords with the assumed shape.
