Companies have put considerable effort into optimizing their processes in the warehouse and in transportation. Operations in the yard, which connects transportation and, specifically, the truck to the warehouse, for both inbound and outbound operations, has in many cases been left behind or ignored. Yard management systems offer the capabilities to make yard operations more efficient by increasing the visibility of gate operations, yard processes and dock-door activities. Yard management includes a set of capabilities that deals with the management and process execution activities related to or impacting a company's shipping yard and dock doors, taking into consideration equipment, facility and employee constraints, as well as activity demand. In its simplest form, yard management can automate the tracking of assets (e.g., trailers or containers) in a yard for the purpose of more efficiently finding and handling them.
