An efficient estimation function for the crew scheduling problem

In this paper we explain an estimation function for the crew scheduling problem in the coach transportation domain. Thanks to this function we obtain an estimation that is very close to the real cost of the solution and we can efficiently prune the search space with a branch and bound approach. Consequently we find the optimal solution in less time than with other estimations such as the Russian doll method. Keywords.
