Goods can be put on the shelves according to SKU attributes/batches, specification restrictions, adjacent to the same batch/same owner, fixed cargo locations of the owner, free cargo location storage, partition/classification storage and other rules to find suitable storage locations for the goods. For products that are not put into the warehouse for the first time, their storage locations can be optimized and adjusted according to the historical frequency and quantity of goods leaving the warehouse. In order to increase the warehouse capacity, it is most ideal to mix “multiple products in one location”. The warehousing system WMS generally supports random storage, but in order to facilitate picking and avoid confusion, overseas warehouses usually place goods according to “multiple locations for one product, one location for one product” or fixed leased storage locations. For example, many sellers have the same or slightly different products, so similar products should be placed in adjacent cargo locations as much as possible.
It is easiest to directly put the goods on the shelves by receiving the original boxes in batches. If multiple products are mixed in a large package or mixed-code boxes for shoes and clothes, it is necessary to print out the list for manual verification, which is time-consuming and labor-intensive, and prone to errors. For goods managed by ID, such as mobile phone IMEI serial numbers and clothing unique codes, the IDs must be scanned and verified piece by piece. Some sellers will receive goods in batches due to insufficient preparation or logistics reasons, causing the warehouse to confuse the batches of goods. After confirming receipt, the process of putting on the shelves begins, and the handover sheet, packing list, receipt record and other materials are archived for future reference. The system generates a shelf instruction according to the predetermined storage strategy and assigns tasks (personnel and logistics equipment). If the number of picking positions is 0, the goods should be put on the shelves first after entering the warehouse and the inventory should be replenished to the maximum. Shelving is divided into scanning and putting on the shelves piece by piece and putting on the shelves in batches of “goods → container → storage location”. The handheld device RF guides the shelving and confirms the shelving, or prints the document for manual shelving and returns the shelving results. FBA transit and returned goods do not need to be put on the shelves or unpacked for inventory, and can be directly transferred (Cross Docking). The goods that have been put on the shelves in the warehouse are reflected as inventory that can be sold and picked.
