A method, system, and computer program product for predicting fuel consumption for a vehicle operation is provided. An associative memory device is accessed, using one or more attributes of an operation plan for the planned vehicle operation, to determine at least one historical vehicle operation from a plurality of historical vehicle operations that is similar to the planned vehicle operation. The associative memory device contains data for a plurality of attributes and collected from the plurality of historical vehicle operations. The at least one historical vehicle operation is determined by applying a respective weight defined within the associative memory device to data values for each of the plurality of attributes. Fuel consumption data for the planned vehicle operation is predicted, based on historical fuel consumption data corresponding to the at least one historical vehicle operation. The predicted fuel consumption data is output.
