Brazilian railroads carry loads through very long trips. A train is driven by a driver and, due to the long trips, the total trip time of the trains is generally higher than the period of the driver's shift and, thus it is necessary to change drivers during the trip in predefined places, called detachments. In the literature, this problem is solved separately by two subproblems: Crew Scheduling and Crew Rostering. Differently, this paper proposes a mathematical model to solve the two subproblems in an integrated way, inspired by the Vehicle Routing Problem of with Multiple Trips and Multiple Depots, to plan the designation of train drivers to drive the trains that will pass through the detachments aiming to minimize the cost with the payment of train drivers. Results show possible cost reductions when compared to the manual planning of the analyzed railway and increasing the shift period, cost reductions can be achieved.Downloads
