Since the 1950s, the operations research community has developed a large number of computer models to aid in the solution of airline scheduling problems. One notable characteristic of these contributions is that each algorithm was developed with its own input and output structures, user interface, and hardware and software requirements. The result is that many of these contributions are under-u...

Within the airline industry’s complex operational environment, any disturbance to normal operations has dramatic impact, and usually imposes high additional costs. Because of irregular events during dayto-day operations, airline crew schedules can rarely be operated as planned. When disruptions occur, crew schedules are affected due to the resulting infeasible flight schedule and improper assig...

BACKGROUND Short-haul pilots have largely been neglected in studies of fatigue, sleep loss and circadian disruption created by flight operations, but anecdotal evidence from pilots suggests that with the increasing amount of low-cost air travel, commercial pilots working short-haul operations may be becoming seriously fatigued. AIMS This study attempted to ascertain how much subjective fatigu...

Operations control is one of the most important areas for an airline company. Through operations control mechanisms an airline company monitors all the flights checking if they follow the schedule that was previously defined by other areas of the company. Unfortunately, some problems may arise during this stage (Clausen et al., 2005). Those problems can be related with crewmembers, aircrafts an...

Airline operations are disrupted frequently. The most impor-tant factors are unstable weather conditions and unpredictable techni-cal aeronautics problems. In a disrupted situation, an airline operatorneeds to quickly adjust the timetable and the resource schedules sothe importance of re-assignment of facilities to flight is much moreclearer. In this study, we considered the...

The purpose of the research discussed in this thesis was to assess the effects of considering airline preferences in runway operations scheduling. This was motivated by the congestion and delays that regularly occur in the air traffic system. Delays cause both cost and inconvenience to airlines and their passengers. Airborne delays increase fuel cost. Delays can cause infeasibility to crew and ...

The crew scheduling problem in the airline industry is extensively investigated in the operations research literature since efficient crew employment can drastically reduce operational costs of airline companies. Given the flight schedule of an airline company, crew scheduling is the process of assigning all necessary crew members in such a way that the airline is able to operate all its flight...
