Abstract

An information processing system (500) determines whether correction is required for a production plan of a production facility (1) that performs production by receiving electric power supply from a power generation facility (5) in which an amount of power generation fluctuates in accordance with a state transition of an external environment. Also, when correction of the production plan is required, the information processing system (500) generates a proposal for correction of the production plan; generates a power accumulation plan, an electrical discharge plan, and an acquisition plan based on the generated proposal for correction of the production plan and a power generation plan of the power generation facility (5) based on a prediction of the state transition of the external environment, the power accumulation plan being a plan about power accumulation of an excess amount of electric power when the amount of power generation exceeds a demanded amount of electric power, the electrical discharge plan being a plan about electrical discharge of the accumulated excess amount of electric power to the production facility (1), and the acquisition plan being a plan about acquisition of a shortfall of the amount of electric power from a power supply facility other than the power generation facility (5) when a total amount of electric power of the amount of power generation and the accumulated amount of electric power is insufficient for the demanded amount of electric power; and determines whether the production plan is corrected by following the proposal for correction of the production plan based on the power accumulation plan, the electrical discharge plan, and the acquisition plan.
