As part of their planning process, airlines construct lines-of-flight (LOFs) − daily repeating sequences of flights, each of which will be flown by a single aircraft. In the week leading up to the actual day-ofoperations, these LOFs are then assigned to specific aircraft (tails), forming multi-day aircraft routings that in turn enable the scheduling of routine maintenance checks. Operational di...

The Next Generation Air Transportation System (NextGen) seeks to reduce gridlock at airports by, among other things, creating a more efficient surface taxi management system. Addressing this situation creates a difficult evaluation problem; how can new scheduling methods be tested? Present methods generally involve either expensive human-in-the-loop experiments or computer simulations that do n...

The co-operation of multiple types of military aircraft has become one of the basic features in air combats. In order to improve comprehensive support capability, how to optimize the resources distribution of ground support equipment is an important content of the air force stations modernization construction. The uneconomic and unreasonable reasons of allocation approach are analyzed based on ...

The maintenance of military aircraft is complex and exhaustive, requiring an accurate training program. This process is not fault tolerant and requires certification renewal periodically. Furthermore, the process involves many professionals and resources, requiring phases of maintenance and verification of the tasks. Cooperation between professionals in the overall process is essential and requ...

An integrated fault diagnosis based fault tolerant longitudinal control system architecture is proposed for civil aircraft which can accommodate partial or total losses of angle of attack and/or calibrated airspeed sensors. A triplex sensor redundancy is assumed for the normal operation of the aircraft using a gain scheduled longitudinal normal control law. The fault isolation functionality is ...

The characteristics of a dynamic implementation of the single-runway aircraft landing problem were analysed using some well-known datasets. Given the nature and degree of complexity of this problem, a specific hybrid algorithm was developed, consisting of a stochastic and a deterministic element. The deterministic scheduler divides the aircraft into logical landing sequences as part of the recu...

This paper proposes a general modeling framework adapted to the feedback control of traffic flows in Eulerian models of the National Airspace System (NAS). It is shown that the problems of scheduling and routing aircraft flows in the NAS can be posed as the control of a network of queues with load-dependent service rates. We can then focus on developing techniques to ensure that the aircraft qu...

Over the past few decades, air traffic has experienced a tremendous Growth. However, as the air traffic develops, the limitation of the runway becomes the bottleneck during the airport operation and scheduling aircraft landing present a complex daily task encountered by most air traffic control towers. In this paper, we study the Multiple Runway case of the Aircraft Landing Problem (MRALP), whi...

We report on the solution of a real-time scheduling problem that arises in the design of software-based operation control of aircraft. A set of tasks has to be distributed on a minimum number of machines and offsets of the tasks have to be computed. The tasks emit jobs periodically starting at their offset and then need to be executed on the machines without any delay. Also, further constraints...
