1. A method comprising:
calculating modeled amounts of fuel predicted to be consumed by a plurality of propulsion-generating vehicles in a multi-vehicle system, wherein the modeled amounts of fuel are calculated using a fuel consumption model that associates different values of the modeled amounts of fuel with operating parameters of the plurality of propulsion-generating vehicles;
measuring consumed amounts of fuel that are consumed by each of the plurality of propulsion-generating vehicles;
calculating difference values between the modeled amounts of fuel and the consumed amounts of fuel for each of the plurality of propulsion-generating vehicles in the multi-vehicle system; and
re-allocating loads placed on each of the plurality of propulsion-generating vehicles based on the difference values of each of the plurality of propulsion-generating vehicles in the multi-vehicle system;
determining the consumed amounts of fuel after re-allocating the loads among the plurality of propulsion-generating vehicles; and
re-calculating the difference values between the modeled amounts of fuel and the consumed amounts of fuel after re-allocating the loads among the plurality of propulsion-generating vehicles, wherein the difference values are smaller after re-allocating the loads among the plurality of propulsion-generating vehicles compared to prior to re-allocating the loads among the plurality of propulsion-generating vehicles, wherein at least a portion of the load is re-allocated from a first propulsion-generating vehicle with larger difference values to at least a second propulsion-generating vehicle with smaller difference values.
