A heuristic procedure for the crew rostering problem.

ABSTRACT

The rostering problem in a mass transit system is that of planning work schedules in a given time horizon so that to balance workload among the drivers. In this paper an integer programming formulation of the problem is given. An iterative heuristic algorithm is described which makes use of a lower bound derived from the mathematical formulation. Furthemore, the algorithm at each iteration solves a Multilevel Bottleneck Assignment problem for which a new procedure that gives asymptotically optimal solutions is proposed. Computational results for both the rostering problem and the Multilevel Bottleneck Assignment problem are given.
