What Are the Key Components of an Automated Warehouse?
Warehouse automation has advanced significantly in just a few short years.
What was once considered the domain of the biggest logistics heavyweights is now a realistic target for businesses of all shapes and sizes.
An automated or “smart warehouse” utilises a range of software, hardware, technology, and data to completely transform a supply chain operation into an efficient, technology-led environment.
However, it’s not just about integrating some robotics and conveyors and calling it a day. It’s about developing an interconnected ecosystem that can scale with your business well into the future.
In this piece, we’ll explore the key tech behind the automation, how the pieces fit together and, most importantly, how to choose the solution that achieves your operational goals.
Why Are Businesses Investing in Warehouse Automation?
Automated and smart warehouses have significantly shifted the way that goods are stored, moved, and shipped.
Increasing consumer demand, delivery speeds, and the increase of e-commerce have fundamentally transformed supply chain operations, pushing companies to adopt more agile and technology-driven solutions.
Automated warehouses are playing a critical role in meeting these challenges.
The following points are no longer negotiable; they are essential for thriving in a hyper-competitive industry, and automation can help achieve them:
Increased Efficiency
Every operation, regardless of the industry they operate in, is looking to increase speed and hit ambitious throughput targets. A smart warehouse can help to automate repetitive tasks, streamline workflows, and redeploy labour resources.
Improved Accuracy
Automation can help to minimise the human error associated with picking, packing, and managing inventory, with more precise processes and reporting.
Tighter Inventory Management
It’s estimated that up to 67% of businesses in the US alone cannot track stock in real time, a problem that costs companies an estimated $1.1 trillion every year. Automated inventory management processes can help your business track real-time visibility, which reduces the risk of both overstock and stockouts.
Optimal Storage Space
Technology such as ASRS and VNAs enables your operation to maximise vertical space, freeing up more room on the warehouse floor.
Improved Working Conditions
With 21% of all workplace injuries caused by lifting, handling, and carrying, automated robotic systems and conveyors reduce the physical strain on workers and enable them to learn how to work safely with robotics.
Scalability
Key events in recent years, such as COVID-19 and the conflict in Ukraine, have disrupted supply chains. Businesses that have adapted and moved quickly are better positioned to scale successfully in the long term. Automation plays a vital role in enabling such agility.
What Are the Key Components of an Automated Warehouse?
In today’s fast-moving logistics world, automated warehouses rely on a range of connected technologies to improve speed, accuracy and flexibility.
These technologies work together to form the foundation of an automated warehouse.
Each element helps make operations smoother, from managing stock and controlling machines to handling goods safely and efficiently.
However, not every solution works for every warehouse. The right choice depends on the layout, the type of stock, and the business needs.
As an automation integrator, we specialise in designing and implementing the right mix of automated technologies tailored to your operation.
Our goal is to help you improve productivity, achieve an ROI, reduce costs, and stay competitive in a rapidly changing market.
Below, we look at the main components of a modern automated warehouse and how they contribute to success:
Control & Management Systems
Supervisory Control & Data Acquisition (SCADA)
SCADA is an industrial control system that is used to monitor, collect and analyse real-time data from the machinery and sensors in the warehouse. This can be displayed on an interface that can be monitored and managed to ensure faults can be detected early.
Benefits:
- Monitors all automated systems in one place
- Detects potential issues before they occur to reduce system downtime
- Allows for remote management and troubleshooting
Manufacturing Execution System (MES)
The MES manages and tracks production-related performance. This is especially useful in warehouses with assembly, kitting, and other value-added tasks.
Benefits:
- Keeps track of real-time stock levels
- Reduces operational error
- Allows the automation to work together
- Allocates tasks and plans material throughput
Warehouse Management System (WMS)
The Warehouse Management System is the control centre of the entire warehouse operation.
This allows operatives to track inventory, manage orders, coordinate automation, and work alongside other software such as the SCADA and MES.
Benefits:
- Keeps track of real-time stock levels
- Reduces operational error
- Allows the automation to work together
- Allocates tasks and plans material throughput
Material Handling & Robotics
Automated Storage & Retrieval Systems (ASRS)
An ASRS is an automated lift, shuttle, or crane that is used to store and pick goods from racking. These are an excellent option when looking to make the most of vertical space when floor space is at a premium.
We recently undertook a project in which we integrated Europe’s tallest automated tote storage and retrieval system at 12 metres high.
Benefits:
- Utilises vertical space
- Increases product retrieval time
- Reduces manual handling errors
- Updates stock in real time when linked to a WMS
Automated Conveyor Systems
Conveyor systems can come in a variety of formats, due to their highly modular nature. Whether using a belt, roller or track, these systems move products around the warehouse.
The complexity depends on what these products are, but many also include sensors to allow products to be diverted to specific sorting areas.
Benefits:
- Sorts and moves products around the warehouse with efficiency
- Reduces manual handling input
- Capable of moving products without delays
- Highly customisable and modular for a range of settings
Automated Vehicles
Automated Guided Vehicles (AGVs) and Autonomous Mobile Robots (AMRs) move products without the need for human-operated forklifts.
AGVs follow fixed paths using tracks, magnets, or sensors, while AMRs navigate dynamically and adjust to changing conditions, all while avoiding obstacles and human workers.
Although not suitable for every warehouse layout or product type, these robots are highly efficient and can be easily scaled to handle peak periods.
Benefits:
- Reduce forklift traffic and improve workplace safety
- Increase transport efficiency and streamline material movement
- Easily scale operations during busy periods or seasonal peaks
- Free up human workers for higher-value tasks
Robotic Picking Systems
Robotic arms and vision systems are used to pick and sort items both quickly and accurately, far more so than human workers, who are liable to fatigue and mistakes.
These types of systems are not suitable for every operation, but are very common in e-commerce and warehouses with a high number of SKUs.
Benefits:
- Can work around the clock without fatigue or error
- Improves picking accuracy
- Reduces labour costs in high-volume areas
- Integrates with WMS to prioritise orders
Very Narrow Aisle (VNA) System
VNA systems are specialised warehouse solutions that maximise storage density by utilising the narrow aisles.
These systems use specialised lift trucks, stacker cranes, or AGVs that can effectively operate in confined spaces. These are most typically guided by wire, rails, or a complete automation system, to ensure more precise navigation and minimise the risk of collisions.
Benefits:
- Increases storage capacity
- Reduces wasted aisle space
- Can be used with ASRS or AMRs
- Needs specific racking to operate effectively
Infrastructure & Environment Systems
Sensors & Connectivity
Sensors and connected devices are integrated technologies used to track goods, monitor machine health, and observe environmental conditions across warehouses, factories, and supply chains.
These devices collect data continuously and transmit it to systems such as Warehouse Management Systems (WMS), SCADA (Supervisory Control and Data Acquisition), and Manufacturing Execution Systems (MES).
Benefits:
- Real-time tracking of stock and assets
- Predicts maintenance needs before breakdowns
- Keeps conditions within set limits
- Supports better decision-making with live data
Automated Packing and Labelling Systems
These systems are machines designed to automatically pack, seal, label, and inspect shipments. They integrate with warehouse operations to streamline the handling of goods, ensuring each package is correctly prepared for storage or dispatch.
Many systems work directly with Warehouse Management Systems (WMS) to track items, verify contents, and maintain compliance with shipping and labelling standards.
Benefits:
- Speeds up packing and dispatch
- Improves accuracy and compliance
- Reduces labour in packing areas
- Works with WMS for tracking and verification
What are the Key Considerations for Investing in Warehouse Automation?
Automation isn’t one-size-fits-all. Whenever we begin a new project, we start by first understanding the current setup.
This strategic phase consists of gathering data, deploying warehouse simulations and modelling technologies, and this all begins before we integrate any automation, robotics or software solutions.
To get real results, you need the right solution for your team, workflow, and operational goals.
Here are a few things you need to consider before deciding whether automation is for you:
Understand Your Current Operational Challenges
Before planning improvements, you need to understand your current operation and its challenges. Ask yourself:
- Are you running out of inventory space?
- Are you tracking stock effectively?
- Are your dispatch processes efficient?
- Where could labour be reallocated for better results?
Outline Your Goals
Once you’ve mapped out your operation and identified inefficiencies, define clear goals:
- Speed up order turnaround
- Scale without adding headcount
- Increase stock capacity without relocating
Familiarise Yourself with Available Technology
Automation options range from conveyor systems and AGVs to scanning tools and full-scale ASRS. The right choice depends on space, budget, and volume.
At Milestone, we are solution-centric, which means we only recommend technology that delivers ROI and meets your operational goals, regardless of the manufacturer.
Budget Your Project
Include integration, training, support, and maintenance in your planning.
The most expensive or flashy technology isn’t always the best. What matters is choosing the solution that works for your goals and delivers measurable results.
We can help you assess costs, plan budgets, and identify the most cost-effective solutions that give you the best ROI.
Prioritise Integration
Your WMS should connect all systems seamlessly, including robots, sensors, and software, to ensure smooth operations.
We can support you in mapping integrations, selecting compatible technologies, and implementing connections that work from day one, avoiding future bottlenecks or system conflicts.
Pilot Before You Scale
Start small. Test, learn, then expand. Piloting is the best way to ensure automation works as expected before full deployment.
We can help you set up the pilot, prioritise integration points, and manage budgets for this phase, making sure the solution is tested effectively, scalable, and aligned with your operational goals.
