Vehicle Routing with Cross-Docking LarsenJesper WenMin CordeauJean-Francois LaporteGilbert 2020 <div>The Vehicle Routing Problem with Cross-Docking is a variant of the classic vehicle routing problem. In this case a cross dock is used to consolidate loads to maximize the utilization of the fleet of vehicles. <br></div><div><br></div><div>The dataset presented here was originally developed for the paper "Vehicle routing with cross-docking" published in Journal of Operational Research Society, vol 60, issue 12, pp 1708-1718 (2009).</div><div><br></div><div>A link to the technical report of the paper is provided here.
