Automated Storage and Retrieval System can achieve high-level rationalization and access automation, its operation is simple, which is a form of relatively high technical level at present. ASRS storage system is a high density system thanks to the reduction of operating aisles and maximized floor and height space. Its reliability allows the daily inventory of stored products and minimizes errors when handling loads. Advantages ? High space utilization The basic starting point of the early conception of three-dimensional warehouse is to improve the utilization rate of space and fully save the limited and precious land. The design of ASRS system is closely related to its planning. Generally speaking, the space utilization rate of ASRS is 2 to 5 times that of ordinary warehouse, which is quite considerable. ? High production management level of enterprises The traditional warehouse is only a place for the storage of cargoes, and its function is only for storage, which is a kind of "static storage". ASRS adopts advanced automatic handling equipment, which can not only make the cargoes in the warehouse according to the need of access, but also can be organically connected with the production links outside the warehouse, which is a kind of "dynamic storage". It is also an obvious technical trend of the development of automatic warehouse today. ? Low human resources cost Intelligent control system can realize real automatic inventory function, avoid the previous heavy manual operation, reduce the intensity of the warehouse management staff, and greatly reduce the error rate of the warehouse operation.
