Robust Passenger Oriented Airline Scheduling

In scheduled air transportation, airline profitability is influenced by the airline's ability to construct flight schedules. To produce operational schedules, airlines engage in a complex decision-making process, referred to as airline schedule planning. Because it is impossible to simultaneously solve the entire airline schedule planning problem, the decisions required have historically been separated and optimized in a sequential manner. We propose a multi-objective integrated robust approach for the schedule design phase, considering the passenger behaviour, deciding jointly flight frequencies and timetable. The objectives are passengers' satisfaction and operator costs. We try to fix the timetable ensuring that enough time is available to perform passengers' connections, making the system robust avoiding misconnected passengers. Some test networks are solved in order to demonstrate the achieved robustness and choose an appropriate objective.
