A yard management system (YMS) supports the efficient flow of work, equipment and materials through the normally enclosed area outside of a warehouse, distribution center or manufacturing facility (known as the yard). A yard management system (YMS) provides an overview of yard operations and supports the planning, direction, monitoring and control of activities. These include scheduling, moving, parking, inspecting and reassigning trucks, trailers and containers in the yard. YMSs are typically used to oversee the gate/kiosk, the yard itself and the inbound and outbound dock door scheduling activities. YMSs are often sold as extended modules of a warehouse management system (WMS) or as an independent suite, and sometimes as part of a transport management system (TMS). The gate, yard and dock components may be sold independently or as a combined solution.
