This system refers to Automated Storage and Retrieval Systems (AS/RS), also known as automated立体 warehouses or high-bay rack warehouses. It typically utilizes racks that are several, dozens, or even tens of levels high, functioning as a warehouse where automated material handling equipment performs all goods inbound and outbound operations. An AS/RS is generally composed of high-bay racks, material handling equipment, control and management systems, as well as civil engineering and public utility facilities.
