Hub location in air cargo transportation: A case study

This paper models constrained choices when establishing cargo hub and spoke networks. A mixed integer linear programming model is developed introducing additional constraints to the traditional model of uncapacitated multiple allocation hub location problem and empirically tested. The tests suggest that aircraft range and trip cost, runway availability and cargo traffic continuity of an airport are major factors affecting hub locations along with the costs of airline movements.
