Previous work introduced the concept of using tactical shortcut options to improve schedule conformance in terminal airspace. When a scheduling point is congested, aircraft are scheduled to longer nominal paths, holding shortcut path options in reserve for tactical use if an aircraft is late, thereby improving the schedule conformance, reducing the required scheduling buffer, and increasing thr...

We study a dynamic repair shop scheduling problem in the context of military aircraft fleet management. A number of flights, each with a requirement for a specific number and type of aircraft, are already scheduled over a long horizon. The overall scheduling horizon is considered to be composed of multiple time periods. The goal is to maintain a full complement of aircraft. We need to assign ai...

Due to the rapid growth of air transport traffic, how to efficiently allocate gates at airports to incoming or outgoing flights has become one of the most important problems which managers of airlines and airports have to concern about. The problem, which can be modeled as a scheduling problem, is often referred to as flight gate scheduling. The main purpose of flight gate scheduling is to find...

In this paper, an airport departure scheduling tool for aircraft is presented based on constraint satisfaction techniques. Airports are getting more and more congested with the available runway configuration as one of the most constraining factors. A possibility to alleviate this congestion is to assist controllers in the planning and scheduling process of aircraft. The prototype presented here...

The problem of deciding how to land aircraft approaching an airport involves assigning each aircraft to an appropriate runway, computing a landing sequence for each runway and scheduling the landing time for each aircraft. Runway allocation, sequencing and scheduling for each aircraft must ensure the scheduled landing time lies within a predefined time window and meet separation time requiremen...

This paper presents a short contribution in air transportation, specifically in scheduling aircraft (plane) landings at Léopol Sédar Senghor (LSS) airport of Dakar. The safety of air navigation of LSS is managed by ASECNA: Agency for Air Navigation Safety in Africa and Madagascar. Scheduling aircraft landing is the problem of deciding a landing time on an appropriate runway for each aircraft in...

An optimization model for a scheduling problem for closely spaced parallel approaches has been formulated. It takes temporal, pairing, sequencing, separation route and grouping constraints into account. Simulations investigated possible advantages of advanced scheduling methods over first-come-firstserved scheduling. Also, this study evaluated the performance differences between the computation...
