Warehouse Automation: A Comprehensive Guide to Modern Logistics Solutions

Warehouse automation refers to the use of technology to perform warehousing tasks — such as inventory storage, material handling, and order fulfillment — with minimal human intervention. Fully automated warehouses are logistics facilities that make use of automated handling equipment and conveying systems to optimize the performance of operations, including truck loading and unloading. Against a backdrop in which companies seek to raise their competitiveness, warehouse automation is a trend seen more and more in logistics nowadays. The goal is to gain in efficiency and productivity: only automated processes can ensure maximum throughput 24/7.

Defining Physical and Digital Automation

There are two different warehouse automation types: physical and digital automation. Both physical and digital automation can significantly improve warehouse and distribution-related procedures in ways that are simply not feasible through traditional means.

• Physical Automation: This encompasses mechanized equipment, like robotic systems, within a warehouse setting. For instance, autonomous mobile robots (AMRs), goods-to-person (GTP) technology, wearable devices, and collaborative robots (or “cobots” for short) are considered forms of physical automation.
• Digital Automation: Digital automation uses software to automate manual processes, such as inventory tracking. A warehouse management system (WMS) is one example of a digital automation solution that captures and analyzes crucial data to drive greater visibility and streamline time-consuming processes.

Automating Core Warehouse Operations

Industrial process automation consists of implementing automated solutions in one or more warehouse operations, e.g., goods receipt, order picking, and stock management. In a fully automated warehouse, all logistics operations have minimal human intervention to boost productivity and limit errors that could undermine the company’s competitiveness.

Goods Receipt and Internal Transportation

In a logistics facility, the goods receiving process is key for effective stock control. The docks can be equipped with automatic truck loading and unloading systems. To streamline movements of goods from the loading docks to the various storage and/or work zones, you can install automated conveying systems such as pallet conveyors and roller conveyors for boxes, totes, and bins. Fully automated warehouses replace manual handling equipment (forklifts) with automated transportation systems that continuously supply the storage, order picking, and dispatch areas.

Automated Storage and Picking Solutions

The extraction and depositing of products is handled by stacker cranes for pallets or boxes. These automatic handling equipment run up and down the aisles of an AS/RS, streamlining goods handling by performing combined cycles. Furthermore, solutions to automate picking include:

• Goods-to-person systems: These automated solutions move the goods to the operator’s station, avoiding unnecessary travel in the facility.
• Automated guided vehicles (AGVs): This automatic handling equipment transfers unit loads between two or more areas of a facility without the need for a driver.
• Pick-to-light: This order-fulfillment technology consists of the installation of numeric displays on shelf locations to guide operators as they perform picking.

Market Projections and the Future of Automation

Warehouse automation demand spiked following the COVID-19 pandemic as e-commerce accelerated and increased the need for warehousing space. While demand started to dip in 2022 due to excess capacity, the warehouse automation industry’s growth rate could return to double digits by 2025. A study by consulting firm McKinsey foresees a highly automated future: “Many operations could be automated by 2030, as artificial intelligence (AI) takes over the many repetitive activities that logistics companies perform.”

Based on market research from Interact Analysis, the following revenue trends are projected for the industry:

• 2021: Industry revenues reached $36.4 billion (30% increase compared with the prior year).
• 2023: Experienced a 1.6% decline.
• 2024: Projected 7% year-over-year uptick.
• 2025: Revenues are projected to reach $51.4 billion (15% increase compared with estimated 2024 levels).

Renewed e-commerce growth and a post-COVID-19 pandemic shift to “just-in-case supply chains” — a strategy focused on keeping large inventories on hand — will drive an uptick in warehouse construction and, ultimately, growth in warehouse automation revenues.
