TITLE Stabilized Column Generation for the Crew Pairing Problem with Time Windows |
 PDF |
|
ABSTRACT Column generation has proven to be efficient in solving the linear programming relaxation of largescale instances of the crew pairing problem with time windows. However, difficulties arise when the instances are highly degenerate. Recent research has been devoted to accelerate column generation while remaining within the linear programming framework. This paper presents an efficient approach to solve the linear relaxation of the crew pairing problem with time windows. It combines column generation, preprocessing variable fixing, and stabilization. The outcome shows the great potential of such an approach for degenerate instances. |
