Claim 9:
10. The operation guidance searching system according to claim 7, wherein the plant model generating unit is configured to perform the machine learning with use of operation data of process variables selected from, as the process variables other than the compression power of the compressor, a process variable group consisting of a temperature of the natural gas on an inlet side of the liquefying heat exchanger, a temperature of the liquefying refrigerant on the inlet side of the liquefying heat exchanger, and a discharge pressure at which the compressor discharges the liquefying refrigerant, and operation data of process variables including, as the manipulated variables, manipulated variables selected from an manipulated variable group consisting of a gas flow rate of the liquefying refrigerant, a liquid flow rate of the liquefying refrigerant, composition of the liquefying refrigerant, the number of rotations of a rotary driver in a case in which the compressor is driven by the rotary driver, and an opening degree of an inlet guide vane of the compressor.
