Abstract
This paper addresses the methodology of reduction of air traffic delay based on integer programming problem. It is assumed that each hub is used as the primary hub airport for the independent. In this paper, we propose the bi-level structure for optimizing the delay recovery: the upper level is the Aviation Operation Center (AOC), which is controlling the hub-to-hub schedule: the lower level is controlled by the Local Hub Operators (LHO), which handle both hub-to-hub and hub-to-spokes schedules. Finally, numerical examples are carried out to show how the proposed method works.
