Aircraft and passenger recovery during an aircraft’s unexpected unavailability

Abstract Airlines design their initial schedules under the assumption that all resources will be available on time and flights operate as planned. However, some disruptions occur due to mechanical failures unexpected delays of maintenance, making aircraft unavailable for a certain period time. These deviations from plan result in high operational costs addition serious inconveniences experienced by passengers. In order handle passenger recovery problems simultaneously, we work integrated networks at which routings itineraries are superimposed. Consequently, could calculate actual profit cancellation cost evaluating each itinerary while considering seat capacity limitations. our computational results, use daily schedule major U.S. airline clearly demonstrate there is an optimal trade-off between operating passenger-related costs.
