What is cross docking in logistics industry?

Cross docking refers to unloading materials or load from a semi automatic truck and loading it automatically in into out bounds trucks and trailers. It is very helpful technique in cost reduction and inventory management .

Cross Dock is a fairly straight forward concept, goods are moved directly from one truck to another, without spending any time being warehoused at the facility where the cross docking occurs. This might be the case in for example a Walmart warehousing center where shipments are coming in from several different vendors, that need to be shipped quickly to individual stores. T.V.s from vendor A, radios from vendor B, and microwaves from Vendor C, might be cross docked from the three trucks that brought them to the facility directly to the trailers that are delivering these goods to the stores.
