1. A fuel consumption prediction system that predicts the fuel consumption of a vehicle comprising a fleet, comprising:
a driver-related variable acquisition unit for acquiring a plurality of driver-related explanatory variables related to attributes of a driver who drives the vehicle;
a vehicle-related variable acquisition unit for acquiring a plurality of vehicle-related explanatory variables related to attributes of the vehicle;
a coefficient setting unit for setting a driver-related coefficient to be applied to the driver-related explanatory variable and a vehicle-related coefficient to be applied to the vehicle-related explanatory variable based on actual values of the driver-related explanatory variables and the vehicle-related explanatory variables; and
an objective variable calculation unit that calculates fuel consumption as an objective variable by using the driver related explanatory variables and the vehicle related explanatory variables, wherein the objective variable calculation unit:
estimates, by adjusting at least one of the driver-related coefficient of the driver related explanatory variable that affects the fuel consumption or the vehicle-related coefficient of the vehicle-related explanatory variable that affects the fuel consumption, the fuel consumption that changes when the at least one of the driver-related coefficient or the vehicle-related coefficient is changed; and
recalculates a predicted value of the fuel consumption when at least one attribute of the driver or attribute of the vehicle is changed by using the driver-related coefficient and the vehicle-related coefficient.
