The ground routing problem consists in scheduling the movements of aircraft on the ground between runways and parking positions while respecting operational and safety requirements in the most efficient way. We present a Mixed Integer Programming (MIP) formulation for routing aircraft along a predetermined path. This formulation is generalized to allow several possible paths. Our model takes in...

This paper investigates the conditions under which dominant airlines internalize self-imposed delays in a deterministic bottleneck model of airport pricing, complementing the similar analysis of Brueckner and Van Dender (BVD, 2008) for the standard congestion-pricing model. A unified model of bottleneck tolling includes untolled, uniform-, coarse-, multi-step-, and continuous-toll equilibria as...

A concept is presented for the development and implementation of a prototype Aircraft Vortex Spacing System (AVOSS). The purpose of the AVOSS is to use current and short-term predictions of the atmospheric state in approach and departure corridors to provide, to ATC facilities, dynamical weather dependent separation criteria with adequate stability and lead time for use in establishing arrival ...

Labor costs are amongst the most important costs for companies in highly developed countries. While manufacturers move their production units en masse to low wage countries, service companies are often tied to their current locations. Unlike production, the service surplus value is often directly related to the place where the service is provided. Moreover, service companies generally require m...

Evolutionary approaches are not usually considered for real time scheduling problems due to long computation times and uncertainty about the length of the computation time. We argue that for some kinds of problems, such as optimizing aircraft landing times, genetic algorithms have advantages over other methods as a best solution is always available when needed, and, since the computation is inh...

Guiding aircraft around the airport’s surface while ensuring conflict-free routings is an important problem at airports. Sequential routing and scheduling algorithms can be advantageous for providing fast online solutions for decision support systems to help controllers. However, the effectiveness of such algorithms can depend upon the sequence of consideration of the aircraft, which is often c...

The fleet assignment problem (FAP) deals with assigning aircraft types, each having a different capacity, to the scheduled flights, based on equipment capabilities and availabilities, operational costs, and potential revenues. An airline s fleeting decision highly impacts its revenues, and thus, constitutes an essential component of its overall scheduling process. However, due to the large numb...

Abstract We present a market model of liberalized aviation with independent decision makers. The consists hierarchical, trilevel optimization problem where perfectly competitive budget-constrained airports decide (in the first level) on optimal runway capacity extensions and airport charges by anticipating long-term fleet investment medium-term aircraft scheduling decisions taken set imperfectl...

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...
