Automated Storage Retrieval System (ASRS) is necessary to consider the storage environment, storage type, shelf structure, and access host. In terms of storage environment, it is necessary to understand that the environment of the client is high temperature, explosion-proof, clean room grade, or low temperature cold chain; in terms of shelf structure, it can be planned as independent or integrated. ASRS can be divided into the type of Mini Load and Unit Load. Unit load for pallet size and the mini load for smaller items stored in totes or cases. Shipping time and product classification are important considerations in this segment. Finally, in the warehouse to carry out product entry and exit management, it is necessary to match the access host, that is, the mechanical equipment for product pick-and-place movement, including stacker, shuttle, and gripping shuttle.
