According to the present invention, a refrigerant amount is easily determined. The present invention is provided with: an operation data acquisition unit which acquires operation data of an air conditioning system; a calculation unit which calculates an index value of a refrigerant amount from the acquired operation data; an inference unit which infers information about the correction of the index value of the refrigerant amount by using a correction model and at least one among the acquired operation data and the calculated index value of the refrigerant amount; and a determination unit which determines the refrigerant amount of the air conditioning system on the basis of the information about the correction of the index value of the refrigerant amount.
