17. AN APPROXIMATE COST-INTEGRATED MODELLING APPROACH TO CROSS DOCK DESIGN
ABSTRACT Cross docking is a form of operating break-bulk freight terminals in which the receiving products are not stocked but, instead, the incoming cargo is internally transferred to be immediately shipped in distribution trucks. With this approach, inventory costs and lead-times are significantly reduced. In this work, an approximate, continuous, non-stat
