3-6. (canceled)

A non-transitory program storage medium storing a computer program which causes a computer to execute:

• acquiring a reduction performance amount and determining a function to output an expectation index by utilizing the reduction performance amount, the reduction performance amount being an energy amount that a consumer has reduced in a set period, the expectation index representing an expected degree of achievement with respect to a reduction target value of energy consumption which is set for the consumer, the function being a function in which the reduction target value is an input, and the expectation index is an output, and the function outputting the expectation index that is higher as the reduction target value is lower and as the reduction performance amount is higher;
• and
• determining the reduction target value of each of the consumers in such a way that a total of the expectation indexes based on the functions determined for the consumers in a community is maximized, when the reduction target amount of energy consumption set for the entire community being a management subject including the consumer is distributed to the consumers in the community.
