| Sumario: | In this paper, we consider the target visitation problem (TVP) which arises in the context of disaster treatment. Mathematically speaking, the problem is concerned with finding a route to visit a set of targets starting from and returning to some base. In addition to the distance travelled, a tour is evaluated by taking also preferences into account which address the sequence in which the targets are visited. The problem thus is a combination of two well-known combinatorial optimization problems: the traveling salesman and the linear ordering problem. In this paper, we point out some polyhedral properties, develop a branch-and-cut algorithm for solving the TVP to optimality and present some computational results. |
