Cross-docking

Cross-docking is a logistical practice of Just-In-Time Scheduling where materials are delivered directly from a manufacturer or a mode of transportation to a customer or another mode of transportation. Cross-docking often aims to minimize overheads related to storing goods between shipments or while awaiting a customer's order. This may be done to change the type of conveyance, to sort material intended for different destinations, or to combine material from different origins into transport vehicles (or containers) with the same or similar destinations. Cross-docking takes place in a distribution docking terminal; usually consisting of trucks and dock doors on two (inbound and outbound) sides with minimal storage space. In the LTL trucking industry, cross-docking is done by moving cargo from one transport vehicle directly onto another, with minimal or no warehousing. In retail practice, cross-docking operations may utilize staging areas where inbound materials are sorted, consolidated, and stored until the outbound shipment is complete and ready to ship.

The goal in using this shape is to maximize the number of inbound and outbound doors that can be added to the facility while keeping the floor area inside the facility to a minimum. Bartholdi and Gue (2004) demonstrated that this shape is ideal for facilities with 150 doors or less. For facilities with 150–200 doors, a "T" shape is more cost effective. Finally, for facilities with 200 or more doors, the cost-minimizing shape is an "X". ==References== Making the Move to Crossdocking, Maida Napolitano and the staff of Gross & Associates, 2000 copyright, www.werc.org
