The Boeing Commercial Airplane Company has developed a freighter network analysis model that can be used for planning and scheduling a fleet of freighter airplanes. The model incorporates both LP and heuristic algorithms and permits the user to determine the maximum profit (scheduled) fleet size, for a given network, set of origin/destination demands, aircraft mix and utilizations, within the limitations of the assumptions and approximations incorporated in the model. The model permits extensive trade studies and sensitivity analyses to be performed with improved accuracy and reduced effort compared to other alternatives.
