1. An upgrade evaluation method executed by a computer, the method comprising:
a communication step of performing data communication with a control device which controls a gas turbine included in a plant;
a performance data acquisition step of acquiring performance data of the gas turbine via the communication step, the performance data including at least an output efficiency of the gas turbine;
an effect calculation step of calculating, based on the performance data, an introduction effect based on a difference in performance between when an improvement function of improving the performance of the as turbine is introduced and when the improvement function is not introduced;
a consideration calculation step of determining a size of a consideration for the introduction effect according to a degree of the introduction effect, wherein the consideration is exchanged between a provider and a recipient of the improvement function; and
an operating state change determination step of determining a physical change in an operating state of the gas turbine,
wherein the effect calculation step and the consideration calculation step are executed at a time period, the time period being determined according to the physical change in the operating state of the gas turbine, to calculate the introduction effect when the time period has elapsed since a previous calculation of the introduction effect, and to calculate the consideration based on the introduction effect each time the introduction effect is calculated.
