Airlines today use robust scheduling to plan ahead for unforeseeable disruptions. We empirically examine three common robust scheduling practices: flexibility to swap aircraft, flexibility to swap gates, and scheduled downtime. To do so, we characterize efficient operating practices in the airline industry by estimating a multiple-outcome, multiple-input production frontier. Estimates of how ro...

A lot of research has been done concerning the airline scheduling problem (ALP) and several of the heuristic methods used show good results. Three methods for resolving ALP problem are presented with their advantages and disadvantages. And we present a new method combining between three methods which gives us best results.

Airline disruption management traditionally seeks to address three problem dimensions: aircraft scheduling, crew and passenger in that order. However, current efforts have, at most, only addressed the first two dimensions concurrently do not account for propagative effects uncertain scheduling outcomes one dimension can have on another dimension. In addition, existing approaches airline include...

Abstract The 2022 Southwest Airline Scheduling Crisis, resulting in approximately 15,000 flight cancellations, demonstrates the challenges of structuring infrastructure systems and their knowledge-making processes for increasingly disruptive conditions. While point-to-point configuration was focus immediate assessments failure, it became rapidly evident that crew-assignment software unable to o...

Demand Response (DR), also known as electric load-shifting program, is a different way of shaping energy demand with the goal to reduce electricity costs for an organization. Extensive prior research studies have demonstrated the effectiveness of the action of DR through the use of operations research methodology e.g. efficient production scheduling. In the real world, schedulers typically issu...

Scheduling problems are found in a lot of application domains. Well known is the scheduling of production where manufacturing operations have to be assigned to limited resources like machines, but also other applications are important, e.g., the scheduling of airline crews, space missions, projects in different domains, clinical surgery, even timetabling and processor scheduling include schedul...

Scheduling landings of aircrafts is an essential problem which is continuously solved as part of the daily operations of an airport control tower. All planes in the airspace of an airport are to be assigned to landing slots by the responsible air-tra c controller. The support of this decision problem with suited optimization approaches has a long lasting tradition in operations research. Howeve...
