Starting point of this project is the (capacitated) vehicle routing problem with private fleet and common carriers (VRPPC). The VRPPC, as discussed over the last ten years, tackles the problem of delivering products from a single central depot (e.g., shipping company) to customer locations. This task is accomplished either by the company’s privately owned homogeneous or heterogeneous vehicle fleet (self-fulfillment) or by employing external common carriers (subcontracting), i.e., less than truckload (LTL) carriers. Goal of the project is to enhance the VRPPC by additional subcontracting options to increase the applicability of the idea of operational outsourcing in practice. Therefore, new subcontracting options have to be evaluated and integrated into the planning model and efficient solution methods to solve the new planning problem have to be developed.
