If a warehouse operation wants to trim costs, where should it start? A good place would be with order picking or warehouse picking automation.

According to Mckinsey, with proper operations analysis, warehouse companies can improve their cost profile with gains of up to 20% — and picking is a central source of labor cost. Additionally, there are other hidden costs associated with picking such as loss of customer satisfaction and brand reputation.

Picking automation improves the outcomes in all cases. Let's find out how

Key Reasons for Warehouse Picking Automation

The fastest, most effective way to improve warehouse picking is through automated warehouse picking. The reasons are simple. Warehouse picking automation accelerates the process, conserves resources, and minimizes error.

Every warehouse order triggers a pick path. For large, complex facilities, these paths are increasingly difficult to optimize. When you add options, such as kitting and order assembly, the complexity skyrockets.

Specialized software platforms can organize and accelerate the automated warehouse picking process. Starting with ecommerce order fulfillment or placement, these platforms map the shortest pick path. Higher picking rates result in faster customer deliveries.

What is Warehouse Picking Automation?

The warehouse picking automation process consists of systems and infrastructure that replace manual handling and movement of items in the warehouse with robots and machines that increase efficiency.

Warehouse picking automation incorporates the latest technology in warehousing to carry out order-picking operations in warehouses. Businesses are using a wide variety of solutions ranging from modern autonomous mobile robots (AMRs) to picking assistance devices (e.g., pick-to-light) and industrial robotic arms, which can be customized to fit any type of facility and item to enhance warehouse picking automation.

Warehouse Automated picking combines IoT and Software

The Internet of things (IoT) in the automated warehouse picking approach enables physical devices and equipment to be sensed and controlled remotely across an existing network infrastructure. IoT networks capture data about objects and devices to be analyzed and managed by computer-based systems.

For warehouses, convenient applications use the data to quickly determine things like the best pick path for any given order. Data can be visualized which further improves warehouse operations since it's much easier to identify choke points.

Here are some examples of IoT and software for warehouse automated picking

Wireless PTL (Pick-to-light devices) - Helps warehouse workers find items by using indicator lights. A simple URL call triggers color-coded inventory devices to light upon shelves, racks, and/or carts, and supports barcodes, QR-Codes, icons, and other data.

Pick to Voice. - Warehouse workers wear a Bluetooth headset that communicates and confirms picks with an operator (which can be automated too). It also enables seamless and continuous pick paths.

Smart glasses / Augmented reality / Pick by vision - Picking instructions and order location/info appear in visual displays on smart glasses. Pickers are free from carrying paper instructions or devices for improved, hands-free workflow.

Robotic Picking - Automated carts and equipment are directed to pick items or gather goods at strategic warehouse locations from human pickers. Robots improve throughput as they can work for many hours with no downtime. Hopstack's advanced algorithms can optimize a robot's path in real-time.

Key Metrics for Measuring Picking Automation Efficiency

One might imagine that this level of connectivity opens up many opportunities to measure warehouse performance with greater detail and precision. Consider these metrics.

Key Metrics for Measuring Picking Efficiency

Travel distance - One of the crucial metrics for warehouse picking automation is the shorter the pick path distance, the faster goods get delivered. Spaces can be automatically measured with a high level of accuracy, and built-in programs reveal shorter routes.

Warehouse space use - IoT in warehouse and software can help optimize warehouse layout. This occurs along with two variables: maximize inventory per square foot/meter and ideal inventory placement for shorter picking times.

Error rate - Error tracking enables managers to improve process accuracy. Automated picking can even see error rates approach 0%. This translates into fewer returns and improved customer satisfaction

Accident/injury rate - By shortening pick paths, workers don't have to exert themselves as much. Hopstack's Digital Warehouse Platform's integration with smart wearables can even track workers' vital signs to ensure employees aren't exhausting themselves.

Top Benefits of Automated Warehouse Picking

What are the business benefits of enable warehouse picking automation? Here are some key factors.

Picking Automation Improves Throughput and Efficiency

Lower costs - Warehouse picking automation optimizes the use of labor, equipment, and storage space. Management tasks are reduced as analysis and performance enhancement are automated. Order return costs shrink too (the cost of returns in the US is estimated at $550 billion per year).

Near real-time tracking. - Warehouse picking automation improves the handling of temperatures and time-sensitive goods, such as perishables and pharmaceuticals—the accurate visibility into storage and delivery results in better margins.

Higher throughput - With efficient warehouse picking software, more items reach their destination per day.

Scaling and forecasting - With improved space and resource use, warehouses can scale faster to meet demand spikes. With automatically collected data, managers make better predictions about inventory flow given seasonal or demand fluctuations.
