Warehouse automation is a powerful tool and can help improve accuracy, efficiency, and reliability while saving on labor costs. According to Inbound Logistics, 65% of the operating budgets in most warehouses are made up of labor costs. As of March 2018, the annual labor expenses for a warehouse with 100 employees were at least $3.7 million. With this in mind, it makes sense that automated warehouses processes can be a game-changer in helping to reduce labor costs. According to Supply Chain Management Review, long-term costs can be significantly reduced through automation.
Some still see the use of machines in warehouses as a threat to their jobs, while others appreciate the possibilities that are inherent in automated systems. Whichever school of thought you subscribe to, the systems are already here and will continue to become more sophisticated and prevalent. With these automated technologies estimated to hit a market value of $22.4 billion by the end of 2021, you need to seriously think about implementing automation in your warehouses.
Understanding what warehouse automation is and how it works will help you remain at the top of the modern warehousing game and remain profitable and competitive in a market that is driven by consumer demand for rapid fulfillment. This guide will help you do exactly that.
What is Warehouse Automation?
Warehousing is rife with tasks that are process-oriented, repetitive, and prone to human error, such as shipping and receiving, picking and packing, and documentation. At its core, this entails identifying everyday tasks and finding creative ways to automate them. In a warehouse, this can involve using warehouse automation robots to fulfill process automation or physical automation.
Process automation involves collecting inventory data and integrating this into a database system. It uses barcode wireless scanning technologies to input and track data. The data is then routed into a centralized repository where it can be retrieved using a software system.
Physical automation incorporates the use of robotic systems, such as autonomous mobile robots (AMRs) automated guided vehicles (AGVs), and goods-to-person (GTP) technology.
Examples of Automation in Warehouses
- Barcode labels and scanning automation: Warehouse operations rely heavily on accurate documentation. The use of barcode labels, warehouse signs, rack labels, and the requisite hardware to read them saves a lot of man-hours in the warehouse documentation process. They also help track the movements of items in and out of the warehouse facility, manage inventory, and identify where specific items are stored, thereby accelerating the picking and packing process. By using the right hardware, software, and scanning technology, the documentation process in the warehouse can be automated using barcodes, eliminating delays and errors.
- Automated guided vehicles: Warehouse automation robots, such as self-guided forklifts and pallet carts are replacing the traditional human-driven forklifts and pallet jacks in warehouses. These automated vehicles follow a digital path in the warehouse to load and unload containers, pallets, and boxes without requiring any human operator.
- Picking automation: One of the most repetitive and time-consuming processes in a warehouse is the picking process. This process, which was formerly entirely dependent on humans and rife with errors, is now being automated using warehouse automation robots combined with modular shelving.
- Inventory automation: Using pen-and-paper systems for inventory counts in a warehouse results in transcription and data entry errors, inconsistencies in inventory, and an overall disruption of operations in a warehouse. Luckily, automation of this process can be easily implemented with cost-effective strategies.
- Back-office automation: Here, inventory data is synced automatically to the warehouse management system (WMS), enabling warehouses to have access to accurate, real-time data.
What Are the Benefits of Warehouse Automation?
Automating your warehouse systems can bring the following benefits:
- Reducing labor costs and other operating expenses
- Maximizing space utilization, layout, and flow in the warehouse
- Increasing the accuracy, efficiency, and productivity of workers while minimizing headcount
- Avoiding a total depletion of stock, since the automated system will automatically reorder items once it hits a predefined threshold
- Improved inventory control and goods tracking using automated storage and retrieval systems (AS/RS).
- Automated data collection and inventory tracking form arrival to shipping, eliminating inventory misplacement, shrinkage, or loss.
- With data at their disposal, operators ensure timely departure and delivery of order shipments, due to improved picking, packing, and shipping efficiency.
How Does It Work?
Warehouse automation works by automatically collecting data and controlling inventory. By implementing a warehouse control system and using the requisite hardware devices and software systems to coordinate everything, you can greatly increase efficiency. Here’s how this is made possible:
1. Use of barcode labels: They form the foundation of automation in a warehouse. They provide a way to track items through the warehouse facility. Barcode labels make it possible to capture data accurately and eliminate errors while tracking or shipping items. Inventory tracking, arrival planning, improved picking efficiency, traffic optimization, and reducing out-of-stock situations are all great benefits of automated warehouses achieved through the use of barcode labels.
2. Use of inventory management system (IMS): This enables real-time visibility of stock levels, product information, and storage locations, giving businesses a high level of inventory control.
3. Use of automated storage and retrieval system (AS/RS): This software system consists of machines that move up and down optimized aisles to retrieve or place items. They provide improved inventory control and item tracking. They also ensure that the warehouse is better laid out, both vertically and horizontally, thus saving on inventory storage. Critical elements of an AS/RS include storage and retrieval machines, automated guided vehicles (AGVs), rack structures, and warehouse control system software (WCS). All these components work together to receive, put away, pick, pack, and ship items along optimized routes.
4. Use of requisite hardware devices: Automation would not be possible without the use of the necessary hardware to help retrieve data from barcode labels and monitor activities. Commonly used devices are portable data terminals, fixed mount computers, barcode scanners, rugged tablets, and label printers.
It’s also possible to automate your shipping process in your warehouse. One way of doing this is to use a third-party shipping software like Easyship. Once you’ve registered for a free account, you can easily sync your orders to your Easyship dashboard and auto-populate shipping information. Then, you can automate various parts of the shipping process, from generated pre-filled shipping labels and customs forms, creating branded tracking pages, and setting up automatic insurance rules.
How Much Does It Cost to Automate a Warehouse?
The cost of a warehouse automation solution will largely depend on how far-reaching and complicated it is. A sophisticated, holistic solution means more equipment and integration with a complex warehouse control system (WCS). This comes with a higher cost, but increased order accuracy and efficiency, and better space utilization. So, you need to look for a software and hardware solution that will work for your business based on the level of automation you want to implement. Let's look at an overview of costs based on automation levels.
- A system that improves conventional picking will cost anywhere between $500,000 to $1 million
- The cost of a mechanized solution ranges from $1 million to $5 million
