The complete guide to smart warehousing: automation, tools and strategies

Warehousing nowadays is not as it used to be. Warehouses are under more pressure than before due to the growth of online shopping and the escalating expectations of customers. Quicker delivery, increased inventory, and fewer workers make it difficult to maintain operations as before.

‍

Smart warehouse technology is where the solution lies. Imagine you provided your warehouse with a brain: it automates repetitive tasks, enables real-time integration of systems, facilitates real-time data sharing, and empowers teams to make better decisions using data. Smart warehouses are using robots, sensors, and other software that share information to ensure that they do not rely on clipboards and manual checks.

‍

The companies that switch are not merely keeping pace but going ahead. The global smart warehouse market is growing at a high rate, and it is not surprising. It enables effective time management, reduces mistakes, prevents operational collapse, and helps prevent your team from burning out.

‍

This blog will delve into what a smart warehouse truly is, the best technologies you require, the advantages you can anticipate, practical situations, potential issues to be aware of, and what the future holds.

What is a smart warehouse?

{{demo_wms="/styles/components"}}

‍

A smart warehouse is a smarter warehouse with a technology-powered approach that uses automation, information, and connectivity to facilitate the easy running of such a warehouse. It goes beyond manual work and creates an atmosphere in the warehouse where machines and systems can communicate with one another, decide, and be flexible to changes on a real-time basis.

‍

Picking and tracing of inventories and restocking are rather people and paper-intensive in a traditional warehouse. This can lead to time and human error wastage and inefficiency. A smart ware, however, integrates the power of automation, sensors, robotics, A.I., and software platforms to enable the warehouse to be more responsive and efficient.

‍

A warehouse can be considered smart with three main parts:

1. Automation

 This includes conveyor belts, robotic arms, autonomous mobile robots (AMR), as well as automated storage and retrieval systems (AS/RS). Automation helps reduce human effort, enabling the more speedy and precise execution of order picking and packing activities daily.

‍

2. Connectivity

 Smart warehouses are built on a network of interconnected devices and systems that work in real-time. This consists of IoT sensors, RF tags, barcode scanners, and a connected machine. When these devices are combined, they provide a real-time, transparent view of the warehouse. For example, when a product is misplaced, the system will immediately recognize it and instruct a robot to retrieve it.

‍

3. Data integration

The main benefit of a smart warehouse is that it collects, analyzes, and acts upon data. Because of modern systems (warehouse management systems (WMS), enterprise resource planning (ERP) systems, and artificial intelligence dashboards), warehouses are making faster decisions in a shorter amount of time. They can track order trends, determine the optimal quantity of items to order, and even identify the most efficient path for pickers or robots to follow.

‍

As these elements operate in combination, they can transform a warehouse into a living system that constantly learns and evolves. The outcome is increased speed in operations, reduced cases of error, reduced costs, and improved experience of both employees and clients.

‍

With the rise of demand for faster and more reliable deliveries, smart warehouses have become a necessity rather than a luxury. The smart warehousing market is projected to reach USD 46.42 billion by 2030, with a CAGR of 8.3%. The growth is a clear sign of the pace at which companies have embraced digitalization and automation into their supply chains.

Top 7 must-have smart warehouse technologies

A smart warehouse employs a variety of technologies to operate at maximum efficiency. These technologies are capable of working in conjunction to ensure that repetitive tasks can be automated, tasks are performed accurately, and operations are conducted at a high level of efficiency. These are seven of the most important technologies that you will encounter in a smart warehouse, and their value.

‍

1. Automated picking tools

Automated picking technologies, including pick-to-light, voice picking, and robotic picking arms, speed fulfillment time and reduce the likelihood of human errors. For instance, in a pick-to-light system, workers have lights indicating the location of storage, which makes the picking process significantly faster, easier, and more accurate. All of automated picking represents a fantastic solution for e-commerce warehouses, which tend to have thousands of different SKUs and short turnaround times.

‍

There are also companies using AI-powered robotic arms that pick individual items, which design the picking arm to adapt to the shape and weight of items, and then automatically sort them as well. Automating this process can reduce the dependency on manual labor and also allow warehouses to operate longer shifts without the fatigue and mistakes associated with human labor.

‍

2. Autonomous mobile robots (AMRs) and automated guided vehicles (AGVs)

AMRs and AGVs are revolutionizing warehouse mobility. Unlike AGVs, which rely on fixed paths for transporting materials, AMRs can adjust their destination or planned path based on current dynamic conditions using sensors and mapping software. 

‍

Amazon (and others) currently use over 750,000 mobile robots to move inventory inside their facilities. These machines don't replace people, but instead assist them by carrying out repetitive and time-intensive tasks, providing workers with more time to apply their skill set in a more fulfilling way.

‍

3. Automated inventory control platforms

Manually tracking inventory is inefficient and can lead to mistakes. Automated inventory management solutions can use sensors, barcode scanners, and real-time tracking to keep an accurate count of stock at all times. 

‍

For example, IoT-based shelves that notify teams when stocks are low or when items are put in the wrong location. Coupled with RFID tags, this will significantly enhance inventory visibility, resulting in reduced shrinkage and overstocking. Companies that use RFID technology have reported inventory accuracy up to 95%.

‍

4. Warehouse management systems (WMS)

A WMS is the brain of a smart warehouse. It does everything needed, including inventory tracking and order management, labor distribution, and shipping. An effective WMS system integrates well with other systems, such as ERP software and transportation systems, to provide a comprehensive view of the entire chain.

‍

New WMS systems that run in the cloud, leveraging AI and machine learning, are performing demand forecasting, recommending layout tuning, and taking it a step further by assigning appropriate tasks to robots and employees based on current workloads. This coordination eliminates potential errors by businesses, lowers operational costs, and aligns customer expectations with delivery.

‍

5. Implementation of the Internet of Things (IoT)

The Internet of Things (IoT) connects devices, systems, and sensors throughout the warehouse. They can monitor a wide array of functions in real-time, including temperature in storage areas, and determine the location of a forklift. If a machine starts overheating or if a cold storage unit fails, they can send an immediate alert, reducing the chance of product loss.

‍

Very large corporations such as Amazon, Walmart, and DHL are already implementing IoT into their warehouse processes. These companies use sensors, RFID tags, and real-time analytics to improve inventory accuracy, minimize downtime, and gain visibility across their supply chains. What we see in these examples is that IoT is not just the future but will define the future of global logistics and set the pace for its scalability and responsiveness.

‍

6. Collaborative robots (cobots)

Unlike traditional robots that operate in an isolated environment, cobots are designed to work alongside workers. Cobots can assist with repetitive tasks such as lifting, sorting, or scanning, while improving efficiency and reducing physical fatigue. 

‍

Cobots are most evident in warehouses where space is limited or workflow is dynamic. Cobots are safer, provide ease of programming, and are more flexible than industrial robots. Most companies that use cobots find that their return on investment is quick, due to the ease of use, improved productivity, and a reduction in workplace injuries.

‍

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

AS/RS systems automate the retrieval and storage of inventory in compact, high-density racking systems. AS/RS systems use equipment like conveyors, cranes, or shuttles to deliver inventory to the requested location in a highly efficient and accurate manner. Generally, AS/RS systems deliver inventory to storage or retrieve inventory from staging. AS/RS systems are very efficient for warehousing in small spaces, especially for high-throughput warehouses. 

‍

For example, AutoStore is a cube-based AS/RS system that allows companies to stack bins vertically, potentially storing up to four times more inventory in the same floor space, depending on layout and use case.  AS/RS systems increase picking efficiency, reduce human error, and reduce total labor cost.

Data protection in smart warehouses

The level of connectivity and the presence of data in smart warehouses make data security an aspect that should not be underestimated. Barcode scanners, inventory sensors, and any other device are included in a digital ecosystem. The volume of sensitive data produced, transferred, and stored in that ecosystem is beyond most people’s imaginations: inventory stocks, consumer data, business performance, etc.

‍

Without any protection, this data is one of the targets.

‍

Why data security matters

Cases of data security breaches may have severe implications such as revenue loss, downtimes, regulatory fines, and reputational losses. Cyberattacks such as ransomware or even phishing can block the system of the warehouse, pause the process, and disclose personal information about customers or suppliers. Some vulnerabilities allow the whole system to be compromised after a single weakness in a sensor or even a 3rd party integration.

‍

Common risks in smart warehouses

• Unsecured IoT devices and sensors.
  
  

• outdated software or firmware.
  
  

• Lack of encryption during data transfer.
  
  

• weak access controls or poor password hygiene.
  
  

• insufficient employee training on cybersecurity best practices.

‍

What are the methods of securing warehouse information?

1. Secure and encrypted use systems

 Choose warehouse management systems with end-to-end encryption at rest and in transit. This makes data impossible to read or steal, even if it is intercepted.

‍

2. Install access control mechanisms.

 Not all people have to have access to everything. Restrict viewing of and editing data using role-based access. The multi-factor authentication (MFA) serves as an additional security measure for key systems.

‍

3. Update systems

 It is recommended that all devices (more so, IoT devices) be patched and updated on a regular basis. A number of cyberattacks exploit the vulnerabilities that can be recognized and ironed out within months.

‍

4. Educate your employees

 The security of a smart warehouse depends on its operators. Implement the basic cybersecurity training of all staff so that they learn how to recognize any form of phishing, remain safe using passwords, and observe safety rules.

‍

5. Audit and monitor activity

. Monitor and identify suspicious activity in real time using automated monitoring. Periodic auditing of the systems assists in fixing the weaknesses before they are used by the attacker.

‍

Bonus: Contract with reputable suppliers.

‍

Ensure your technology partners have a high regard for security, are updated regularly, and help with compliance needs such as the GDPR or ISO 27001. A safe vendor is a safe prolongation of your own operation.

‍

With the increased intelligence of the warehouses comes the threats. One thing you cannot avoid doing is making cybersecurity part of your smart warehouse plan.
