Claim:
1. An information processing method executed by a system that includes a plurality of air-conditioning apparatuses respectively arranged on each of a plurality of subareas within a target area and a program development device coupled to the plurality of air-conditioning apparatus, the information processing method comprising: measuring, by the plurality of air-conditioning apparatuses, a power consumption for each of the plurality of air-conditioning apparatuses; setting, by the program development device, an area target amount of reduction in power consumption of the target area based on the power consumption measured by each of the plurality of air-conditioning apparatuses; acquiring a predicted value and a measured value of outdoor temperature at each of the plurality of subareas; calculating, for each of the plurality of subareas, a prediction error of outdoor temperature by calculating a difference between the predicted value and the measured value; calculating, for each of the plurality of subareas, a utilization rate indicating a rate of assignment of the area target amount of reduction in power consumption by solving an objective function generated based on the area target amount of reduction and a variance of the prediction error of outdoor temperature; assigning, to each of the plurality of subareas, a subarea target amount of reduction in power consumption based on the utilization rate; and operating, by the plurality of air-conditioning apparatuses, to maintain a setting temperature determined based on the subarea target amount of reduction assigned for each of the plurality of subareas.
