A large neighbourhood search heuristic for the aircraft and passenger recovery problem

4OR, 2010
This paper introduces a large neighbourhood search heuristic for an airline recovery problem combining fleet assignment, aircraft routing and passenger assignment. Given an initial schedule, a list of disruptions, and a recovery period, the problem consists in constructing aircraft routes and passenger itineraries for the recovery period that allow the

A Bundle Algorithm Approach for the Aircraft Schedule Recovery Problem During Hub Closures

Transportation Science, 2003
A bundle algorithm is presented to solve a multicommodity network model for determining a recoveryplanfor a single carrier with multiple fleets following a hub closure. The algorithm is shown to provide feasible near-optimal solutions much more quickly than can be obtained using a standard commercial mixed-integer programming code (CPLEX).

A mathematical model for integrated aircraft and crew recovery after a disruption: a Benders’ decomposition approach

Journal of Modelling in Management, 2022
Purpose Airline scheduling is an extremely complex process. Moreover, disruption in a single flight may damage the entire schedule tremendously. Using an efficient recovery scheduling strategy is vital for a commercial airline. The purpose of this paper

Optimization of short-haul aircraft schedule recovery problems using a hybrid multiobjective genetic algorithm

Expert Systems with Applications, 2010
A hybrid multiobjective genetic algorithm is presented in this paper to find an efficient solution for the daily short-haul aircraft schedule recovery problems which usually happen due to some disturbance events and require a time-sensitive solution to meet various hard constraints and soft objectives.

A hybrid multiobjective genetic algorithm on optimizing aircraft schedule recovery problems under short-time response

2008 IEEE International Conference on Systems, Man and Cybernetics, 2008
This article presents a hybrid multiobjective genetic algorithm to aid the tracking of the daily aircraft schedule recovery problem under disturbance events such as severe weather and mechanical problems. The proposed algorithm extends from the original method of inequality-based multiobjective genetic algorithm (MMGA) and utilizes an adaptive ...
