A Hybrid Ant Algorithm for the Airline Crew Pairing Problem

摘要

This article analyzes the performance of Ant Colony Optimization algorithms on the resolution of Crew Pairing Problem, one of the most critical processes in airline management operations. Furthermore, we explore the hybridization of Ant algorithms with Constraint Programming techniques. We show that, for the instances tested from Beasley's OR-Library, the use of this kind of hybrid algorithms obtains good results compared to the best performing metaheuristics in the literature.
