Put-Away: Technology and Automation

Put-away is the warehouse process of moving received goods from the receiving dock to their designated storage locations. It involves verification, sorting, scanning, and updating the warehouse management system to maintain inventory accuracy and optimize space and retrieval efficiency.

Put-Away: Technology and Automation

Put-Away benefits significantly from modern warehouse technology and automation. When combined with robust operational rules, systems such as Warehouse Management Systems (WMS), Radio Frequency (RF) devices, voice-directed solutions, conveyors, and automated guided vehicles (AGVs) streamline put-away tasks, reduce human error, and enable higher throughput with consistent accuracy. This entry examines technologies, integration approaches, and practical examples for implementing automated and semi-automated put-away workflows.

Core technologies used to support and automate put-away:

• Warehouse Management Systems (WMS): Central to directed put-away, slotting logic, task batching, and verification. A WMS assigns locations based on rules such as product dimensions, demand profiles, weight, hazardous classification, and temperature requirements.

• RFID and barcode scanning: Provide fast, reliable identification at receipt and during placement. RFID can enable bulk reads and reduce scan time for pallets or cases.

• Mobile computers and RF guns: Deliver put-away tasks to operators, show location maps, capture scans, and confirm task completion in real time.

• Voice-directed put-away: Hands-free guidance improves operator ergonomics and accuracy, particularly where scanning isn’t practical.

• Conveyors, Sortation, and Ro-Ro systems: Move goods to staging or direct storage areas with minimal manual handling—useful in high-throughput e-commerce and parcel operations.

• Automated Storage and Retrieval Systems (AS/RS): Cranes and shuttle systems place pallets or totes into high-density storage with precise control and minimal labor.

• Autonomous Mobile Robots (AMRs) and AGVs: Transport pallets or racks between receiving and storage zones on scheduled or on-demand tasks, reducing operator travel time.

• Machine vision and IoT sensors: Capture images for verification, detect misplacement, and monitor storage conditions such as temperature or humidity.

How technology changes the put-away workflow:

• Automated decisioning: The WMS uses live inventory, order forecasts, and slotting algorithms to determine the optimal storage location for each unit at the point of receipt.

• Directed task issuance: The system creates tasks and assigns them to the best available mobile worker or robot based on proximity, skillset, and workload.

• Execution and capture: Operators follow step-by-step instructions via RF, voice, or mobile app, scan the item and the destination, and confirm placement. In automated flows, the AS/RS or AMR executes the placement and the system records it.

• Verification and reconciliation: The system uses scans, RFID reads, or vision checks to validate correct placement and triggers exception workflows when discrepancies occur.

Integration considerations:

• Real-time data flow: Accurate put-away depends on timely inventory and location availability updates. Ensure low-latency integration between WMS, material handling control systems (MHS), and ERP.

• Device interoperability: Standardize messaging and data formats so RF devices, voice systems, and automation controllers can exchange tasks and confirmations reliably.

• Scalability and flexibility: Select systems that can adapt to seasonal spikes, SKU growth, and changes in SKU mix without requiring major reconfiguration.

• Safety and regulatory compliance: Automated systems must include safety interlocks, clear signage, and hazard detection to comply with workplace safety regulations.

Practical examples of technology-enabled put-away:

• E-commerce fulfillment center: Incoming totes are routed by conveyors to a robotic pick-and-place station that places totes into carousels or AS/RS locations. The WMS updates locations instantly, enabling rapid pick availability for same-day orders.

• Cold storage distribution: RFID tagging combined with a directed put-away algorithm ensures temperature-controlled items are assigned to zones with adequate capacity and temperature history to meet shelf-life requirements.

• High-mix manufacturing spare parts: AMRs transport labeled kitting pallets from receiving to multi-level reserve racks while the WMS reserves forward pick slots for fast-moving parts and triggers automatic replenishment tasks.

Benefits and ROI drivers:

• Reduced labor and travel time: Automation and optimal task assignment cut total operator travel and allow higher throughput per labor hour.

• Higher accuracy: Scanning and automated placement reduce mislocations, lowering the cost of cycle counts and inventory reconciliation.

• Improved space utilization: AS/RS and high-density automation increase usable storage volume in the same footprint.

• Faster availability: Real-time inventory updates shorten the time from receipt to pickable stock, supporting faster order lead times.

Common pitfalls when automating put-away:

• Poorly defined business rules: Automation magnifies poor logic; invest time in slotting and rules design before implementing automated tools.

• Underestimating exceptions: Ensure human workflows exist to handle damaged goods, odd dimensions, and off-spec cases.

• Integration gaps: Incomplete integration between WMS and automation controls leads to deadlocks or misplaced goods.

In summary

Technology and automation transform put-away from a manual chore into a strategic enabler of warehouse performance. The key to success is aligning systems, rules, and human workflows so that put-away tasks are executed quickly, accurately, and safely, and the warehouse can convert inbound flow into available inventory with minimal friction.
