Accuracy is paramount in warehouse operations. Automating your warehouse reduces the risk of human errors associated with manual operations. Automated systems provide precise tracking and real-time updates, minimising discrepancies and losses. With automation, you’ll experience better inventory accuracy, lower chances of shipping errors, and reduced returns due to fewer mistakes.


Warehouse Automation Strategies


1. Automated Storage and Retrieval Systems (AS/RS)

Automated Storage and Retrieval Systems, also known as AS/RS, are computer-controlled systems used in warehouses for quick, accurate, and safe material handling. They automatically place and retrieve loads from specific storage locations, maximizing space utilization and increasing throughput.

Here are some of the benefits offered by ASRS –

  • Improved accuracy: AS/RS systems drastically reduce errors in picking and putting away items, thereby improving accuracy levels.
  • Increased productivity: These systems can operate round the clock, raising warehouse productivity significantly.
  • Enhanced safety: AS/RS minimizes the need for manual labour, reducing the risk of work-related injuries.


Examples of AS/RS systems

Various AS/RS systems can be implemented based on specific warehouse needs. Unit-load systems are ideal for large, heavy items, while mini-load systems are suitable for small parts. Vertical lift modules and horizontal carousels are also popular choices for different warehouse environments.


2. Pick-to-Light Systems

Pick-to-light systems are a key part of many efficient warehouse operations across the globe. This intuitive automated picking technology simplifies the task by using a series of lights and quantities displayed on a light module at storage locations. When an order needs picking, the light modules light up to guide workers to the correct product locations.
Integrating pick-to-light systems in your warehouse automation strategy offers numerous benefits. These include:

  • Shortened order fulfilment cycle time
  • Increased productivity due to reduced picking errors
  • Enhanced operator productivity as workers no longer need to read paperwork or handheld devices
  • Easy scalability to increase picking zones and order volume when needed


Examples of pick-to-light systems in action

Many organizations have successfully implemented this system to raise their productivity and efficiency. Amazon, known for its sophisticated warehouse operations, utilizes pick-to-light technology to streamline its picking process. Another example is Zara, a Spanish fast-fashion retailer, which uses pick-to-light systems in its distribution centres to speed up order fulfilment and maintain its fast-fashion business model.


3. Conveyor Systems

Conveyor systems have gained notoriety as a major player in warehouse automation. These are mechanical devices designed to move items efficiently from one place to another within a warehouse setting, providing a less labour-intensive and more efficient way of transporting goods.
Implementing conveyor systems can lead to an array of benefits for a warehouse operation. Here are a few to consider:

  • Increasing productivity by quickening the pace of picking, packing, and sorting operations.
  • Enhancing safety by reducing the need for heavy lifting and the potential for worker injury.
  • Saving valuable floor space as they can be designed to fit around existing warehouse layouts.

There are several types of conveyor systems used in warehouses, each with its specific applications. Here are a few:

  • Roller conveyors are suitable for moving boxes and pallets.
  • Belt conveyors can handle a variety of materials, from small parts to large boxes. 
  • Overhead conveyors are ideal for parts handling and suspension, freeing up floor space.

Ultimately, the type of conveyor system used depends on the size, weight, and type of the products being handled, as well as the layout and needs of the warehouse.


4. Robotic Process Automation (RPA)

Robotic Process Automation (RPA) is a technology application that uses artificial intelligence and machine learning capabilities to manage repetitive tasks. In the context of warehouse operations, RPA can automate tasks that were previously performed by humans, such as packing, sorting, and palletizing, thus creating a more efficient and productive workflow.

The primary objective of RPA in warehouse operations is to increase productivity and reduce costs. By automating repetitive tasks, warehouses can significantly improve their operations throughput and overall efficiency.

RPA has a vast range of advantages when implemented to perform tasks like sorting, packing, and palletizing. These advantages include enhanced accuracy, increased speed, and improved scalability. It also frees up human employees to perform more skilled tasks and strategic planning.

Companies such as Amazon and DHL have extensively adopted RPA to streamline their warehouse and logistics processes.
