Optimal aircraft routing in a constrained path-dependent environment
… generating a route of flight for an aircraft, or a group of aircraft flying in formation, from an origin to a destination in the presence of threats. The threats encountered at a point of the route are a function of the route used to arrive there. The route is constrained by limits on …

Empirical investigations of properties of robust aircraft routing models
… complex problems. This research focuses on the aircraft routing phase. We introduce the concept of robustness in aircraft routing problems, and find solutions that can stand uncertainty. We categorize the delays in flight operations into two components – independent delay and propagated delay. …

Minimizing airline passenger delay through integrated flight scheduling and aircraft routing
… or postpone some flight legs or to re-route some aircraft to recover the rest of the schedule; and 2) building robustness into the schedule in the planning stage. By robustness we mean the ability to absorb flight delays so these effects are minimized on passengers and crews. In many cases, trying …

Integrated Airline Operations: Schedule Design, Fleet Assignment, Aircraft Routing, and Crew Scheduling
… their operating costs by managing their flights, aircraft, and crews effectively. This motivates the extensive use of analytical techniques to solve complex problems related to airline operations planning, which includes schedule design, fleet assignment, aircraft routing, and crew scheduling. The …

Degradable airline scheduling : an approach to improve operational robustness and differentiate service quality
… fleet assignment model), and (3) with aircraft routing (degradable aircraft routing model). Each problem is modeled as an integer program. Search algorithms are applied to the degradable aircraft routing model, which has a large number of decision variables. Results indicate that we can …

Integrated Aircraft Fleeting, Routing, and Crew Pairing Models and Algorithms for the Airline Industry
… and by efficiently allocating their resources of aircraft and crews so as to reduce operational costs. In practice, this is achieved based on demand forecasts and resource availabilities through a structured airline scheduling process that is comprised of four decision stages: schedule planning, …

Airline schedule planning and operations : optimization-based approaches for delay mitigation
… system performance and reducing delays for aircraft, crew and passengers. As a strategic approach, we study robust optimization models, which capture possible future operational uncertainties at the planning stage, in order to generate solutions that when implemented, are less likely to be …

Approaches to incorporating robustness into airline scheduling
… how to create multiple optimal solutions to the Aircraft Routing problem and suggest how to evaluate robustness of those solutions. Other potential methods for increasing robustness of airline schedules are reviewed.
