An automated Storage & Retrieval System (ASRS) requires all of the following EXCEPT __________.

• A. A pick to light system
• B. Pallet storage
• C. Barcode scanners
• D. Inventory management software

Answer: (A)

An ASRS is built to automatically store and retrieve goods, so it relies on components that enable automated handling, tracking, and control. Pallet storage provides the physical payload and a stable, scalable means to stack items inside the automated racks. Barcode scanners (or similar identification tech) are used to uniquely identify items and locations as moves occur, feeding accurate data to the system. Inventory management software ties everything together, maintaining real-time stock levels, locations, and order instructions so the automation can operate smoothly. A pick-to-light system, while helpful for guiding human pickers and reducing errors in manual or semi-automatic picking, is not a required element of an ASRS. The automation can function without it, relying on the storage/retrieval hardware, identification, and software to manage operations.
