| Tiivistelmä: | In this paper, a new two-stage exact approach for solving a real vehicle routing problem is shown, along with decision making software. In the firs stage, all the feasible routes are generated by means of an implicit enumeration algorithm; afterwards, an integer programming model is designed to select in the second stage the optimum routes from the set of feasible routes. An interactive decision support system was also developed. The system was tested with a set of real instances and, in worst-case scenario, the routes obtained ranged from a 7% to 12% reduction in the distance travelled and from a 9% to 11% reduction in operational costs. |
