Maintenance and Crew Considerations in Fleet Assignment

Integrated Airline Fleet and Crew Robust Planning

The airline fleet assignment problem involves assigning aircrafts to flights to maximize profit. Different fleet assignment solutions cause dramatically different performance in subsequent crew planning and operational processes. We have developed an integrated fleet and crew robust planning method to provide fleet assignment solutions that are both friendly to crew planning and robust to real ...

Airline fleet assignment concepts, models, and algorithms

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...

Models and Algorithms for an Integrated Fleet-Assignment, Aircraft-Routing and Crew-Pairing Problem

We study an optimization problem of a regional airline company. The problem integrates three stages of the planning process that are typically solved in sequence: fleet assignment, aircraft routing and crew pairing. Aircraft maintenance is also taken into account. We present two mathematical formulations for the integrated problem. One formulation could be considered the natural model where bot...

Integrated Airline Operations: Schedule Design, Fleet Assignment, Aircraft Routing, and Crew Scheduling

A New Model for Fleet Assignment Problem, Case Study of Iran Air Network at Vision 2036

The fleet assignment problem (FAP) assigns the type of airplane at each flight segment. Since airplane is an expensive resource, poor fleet assignment can cause a great increase in costs of airlines. There are so many consideration which should be tackled in formulation of a FAP problem, especially the parameters regarding to the airplanes. This paper presents a novel, mixed integer programing ...
