Since Amazon deals with such a wide variety of products there are a few exceptions to the ule. Really fast-moving articles do not adhere to the same storage system since they enter and leave the warehouse so quickly. Really bulky and heavy products still require separate storage areas and perishable goods are not ideal for obvious reasons.
Every single shelf space inside an Amazon warehouse has a barcode. And every incoming product that requires storage is assigned a specific barcode that matches the shelf space in which it will be stored. This allows free space to be filled quickly and efficiently.At the heart of the operation is a sophisticated database that tracks and monitors every single product that enters/leaves the warehouse and keeps a tally on every single shelf space and whether it’s empty or contains a product.
Chaotic storage is like organized confusion. It’s an organic shelving system without permanent areas or sections. That means there is no area just for books, or a place just for televisions (like you might expect in a retail store layout). The product’s characteristics and attributes are irrelevant. What’s important is the unique barcode associated with every product that enters the warehouse.
