Abstract

We report about a study of a simulated annealing algorithmfor the airline crew pairing problem based on a run-cutting formulation. Computational results are reported for some real-world short- to medium-haul test problems with up to 4600 flights per month. Furthermore we find that run time can be saved and solution quality can be improved by using a problem specific initial solution,by relaxing constraints “as far as possible”,by combining simulated annealing with a problem specificlocal improvement heuristicand by multiple independent runs.
