IoT optimization: How logistics and intralogistics use the Internet of Things (IoT) to improve warehouse processes

The logistics industry is facing a profound transformation, driven by technological innovations such as the Internet of Things (IoT). One of the pioneers in this area is DHL Supply Chain, the world's leading provider of contract logistics and part of the Deutsche Post DHL Group. By deploying IoT technologies in warehouse environments, DHL aims to increase the efficiency of its operations while improving workplace safety. These developments mark an important step towards a fully digitalized supply chain, which could permanently change not only the way warehouses work, but also customer service.

Back in 2017, DHL launched pilot projects at three locations in Germany, the Netherlands and Poland in collaboration with the technology giant Cisco and the innovative startup Conduce. These projects served to test the possibilities of IoT in real warehouse environments and gain valuable insights into optimizing processes. The results of these tests were promising and demonstrated how IoT technologies can be used to make operations more efficient and identify potential security risks early.

How does IoT work in logistics?

The Internet of Things describes a network of physical objects – called “things” – that are equipped with sensors, software and other technologies to exchange data and communicate with each other. In logistics, this specifically means that various devices and machines within a warehouse can be networked with one another in order to record and evaluate data in real time. At DHL, for example, scanner sensors, transport and loading devices as well as the company's own warehouse management system are used to continuously collect information about the status of goods and processes.

A central element of this technology is the graphical representation of operating data in real time. Heatmaps can be used, for example, to identify bottlenecks or peak times in warehouse operations. This visual presentation enables those responsible on site to react quickly to changes and make necessary adjustments. The ability to monitor operational processes in real time represents a significant improvement over traditional methods that often only analyzed data after the fact.

Increased efficiency through real-time data analysis

The advantages of this real-time data analysis are many. On the one hand, warehouse processes can be made more efficient by targeting resources such as personnel or machines where they are needed most. On the other hand, continuous monitoring allows potential problems to be identified and resolved at an early stage. This can, for example, help minimize machine downtime or reduce safety risks for employees.

A concrete example from the pilot projects shows how DHL was able to use IoT technologies to determine the number of warehouse employees and transport equipment in relation to the upcoming orders. This data was then visually processed and helped to avoid bottlenecks and optimally plan the deployment of personnel. Such measures not only contribute to increasing efficiency, but also improve working conditions for employees.

Safety in the workplace through IoT

In addition to increasing efficiency, the issue of security also plays a central role in the implementation of IoT technologies in warehouse environments. By continuously monitoring devices and machines, potential safety risks can be identified at an early stage. For example, irregularities in the operation of machines can be detected before a failure or even an accident occurs.

In addition, the IoT system makes it possible to analyze employee movement patterns within the warehouse. This makes it possible to identify dangerous areas where accidents may occur more frequently. Based on this data, targeted measures can then be taken to minimize the risk for employees - be it through additional safety precautions or redesigning the workplace.

The digital supply chain of the future

The digitalization of the supply chain is a central goal of DHL. The company is already working closely with customers and technology experts to develop proactive solutions to the challenges of the future. It's not just about making existing processes more efficient, but also about enabling completely new business models.

An example of this is the integration of IoT technologies along the entire value chain - from goods receipt through storage to delivery to the end customer. By using networked devices, all steps of the logistics process can be seamlessly connected. This not only leads to greater transparency within the supply chain, but also enables more precise planning and control of processes.

Another advantage of the digital supply chain is the possibility of predictive maintenance. By continuously monitoring machines and devices, maintenance needs can be identified at an early stage - even before a failure occurs. This not only reduces downtime, but also reduces the cost of repairs.

Implementation challenges

Despite the many benefits, implementing IoT technologies also comes with challenges. One of them is data security. As more and more devices are connected to each other and exchange sensitive information, the risk of cyberattacks also increases. Companies must therefore ensure that their IT infrastructure is adequately protected and that sensitive data does not fall into the wrong hands.

Another challenge is that many companies are not yet fully prepared for a digitalized supply chain. There is often a lack of both technical know-how and the necessary investments in modern technologies. However, DHL has already recognized that close collaboration with technology partners such as Cisco is necessary to successfully overcome these hurdles.

The future belongs to the Internet of Things

DHL's pilot projects have shown that the Internet of Things offers enormous potential for the logistics industry. By using networked devices, processes can be made more efficient and security risks can be minimized. At the same time, the IoT opens up completely new possibilities for a transparent and flexible supply chain.

DHL has positioned itself as a pioneer in this area and is working intensively to further develop its digital solutions. It's not just about optimizing existing processes - it's about creating a completely new way of working: "We don't just want to react to changes," says a company spokesman, "but we want to actively shape them."

In a time of increasing globalization and growing demands for flexibility, the Internet of Things will undoubtedly play a key role - both for DHL and for the entire logistics industry worldwide.
