A Branch-First, Cut-Second Approach for Locomotive Assignment

Ziarati, Koorush; Soumis, François; Desrosiers, Jacques; … - In: Management Science 45 (1999) 8, pp. 1156-1168

The problem of assigning locomotives to trains consists of selecting the types and number of engines that minimize the fixed and operational locomotive costs resulting from providing sufficient power to pull trains on fixed schedules. The force required to pull a train is often expressed in...
