An Efficient Airline Re-Fleeting Model for the Incremental Modification of Planned Fleet Assignments

Transportation Science, 2000
Airlines typically manage their annual business cycle by subdividing the year into a sequence of scheduling periods that span about a month each. Fleet assignment represents an important step in the planning process for each new scheduling period and is usually undertaken using computer-based optimization models.

Swapping Applications in a Daily Airline Fleet Assignment

Transportation Science, 1996
An airline's schedule consists of a set of flight legs that it is scheduled to fly. A fleet assignment is an assignment of equipment types (such as a 757, 767, F100 etc.) to each of the flight legs. The fleet assignment is called a daily fleet assignment if the same assignment of equipment types is used every day of the week.

Auswirkungen eines kontinuierlichen Fleet Assignment Prozesses

2006
Durch die Simulation eines Revenue Management Systems wie es bei Fluggesellschaften in der Praxis eingesetzt wird, konnte ein positiver Erloseffekt fur einen kontinuierlichen Fleet Assignment Prozess nachgewiesen werden. Die Realisierung eines Grosteiles des Potenzials bis drei Wochen vor Abflug ist operationell umsetzbar.

Integration of Fleet Assignment and Aircraft Routing

Transportation Research Record: Journal of the Transportation Research Board, 2005
Fleet assignment and aircraft routing are two sequential steps in airline capacity planning. The fleet assignment model allots the scheduled flights covered by a type of aircraft on the basis of aircraft availability, and the aircraft routing model generates a route for each particular aircraft to ensure that the path-specific requirements for ...

Incorporating Fleet Assignment with Aircraft Allocation to Measure Fleet-Level Metrics

2013 Aviation Technology, Integration, and Operations Conference, 2013
Studies of the environmental and economic impact of new aircraft requires both predictions of the new aircraft’s performance and a representation of how airlines will use the new aircraft as part of their fleets. Aircraft allocation and fleet assignment allow the study of fleet-level metrics given new aircraft technologies or concepts, because these ...

Real-time Truckload Fleet Assignment and Scheduling Problem

Sixth International Conference on Intelligent Systems Design and Applications, 2006
The paper introduces a generic real-time truckload fleet assignment and scheduling problem, which includes the consideration of various costs associated with trucks' empty travel distances, jobs' delayed completion times, and job rejections. A mixed integer programming formulation for the off-line version of the problem is proposed.

US Airways Automates Its Weekend Fleet Assignment

Interfaces, 1999
Assigning fleets of aircraft to a weekend schedule is more difficult than assigning them to a weekday schedule. The reason is that we must balance two conflicting objectives. We must meet passenger demand that is different from weekday demand. We must also minimize the costs of realigning airport facilities and personnel that we would incur by ...

Air fleet assignment model

2014
Diese Arbeit behandelt eine Annäherung an ein reales Problem durch Einsatz von ganzzahliger Programmierung (IP), die zum einen auf das Problem der Kursplanung (course timetabling) basiert und zum anderen eine Spezialbehandlung für diesen Fall erfordert.

Fleet Assignment Problem in Hub-and-Spoke Network

2008 International Seminar on Business and Information Management, 2008
The fleet assignment is a key factor affecting the operating costs of an airline. In this paper, we address the fleet assignment problem (FAP) in which the flight route is taken into account. On the basis of the analysis of the airlinepsilas cost structure and the space and time method, a more comprehensive mathematical model with regard to the hub-and-
