What is industry 4.0?

Industry 4.0 overview

Industry 4.0 has reinvented how businesses design, manufacture, and distribute their products. Technologies such as Industrial Internet of Things (IIoT), cloud computing, and AI are now deeply woven into the manufacturing process. This unified and integrated approach to manufacturing results in products, factories, and assets that are connected and intelligent.

Today’s Industry 4.0 initiatives also seek to develop symbiotic and rewarding collaborations between people and technology. When the accuracy and speed of 4.0 tools come together with the creativity, talent, and innovation of your people, you achieve a win/win for both your workforce and your bottom line. Your manufacturing operations become more efficient and productive, and your teams are relieved of many mundane and repetitive tasks—giving them the opportunity to collaborate with smart technologies and better equip themselves for the evolving technological landscape and the AI-powered future of work.

Industry 4.0 definition

Industry 4.0 can be defined as the integration of intelligent digital technologies into manufacturing and industrial processes. It encompasses a set of technologies that include industrial IoT networks, AI, Big Data, robotics, and automation. Industry 4.0 enables smart manufacturing and the development of intelligent factories. It aims to enhance productivity, efficiency, and flexibility while enabling more intelligent decision-making and customisation in manufacturing and supply chain operations.

And any definition of Industry 4.0 would also have to include its origin from the term Fourth Industrial Revolution. Since the 1800s, we have experienced four industrial revolutions. They were called “revolutions” because the innovation that drove them didn’t just slightly improve productivity and efficiency – it completely revolutionised how goods were produced and how work was done. We are now in the Fifth Industrial Revolution, also known as Industry 5.0.

First Industrial Revolution

By the early 1800s, the First Industrial Revolution was underway. The invention of the steam engine reduced industrial reliance on animal and human labour, ushering in a new age of manufacturing and precision engineering.

Second Industrial Revolution

A century later, the growing use of petroleum and electric power meant that machinery could be leaner and less cumbersome. The Second Industrial Revolution was driven by the assembly line and mass production processes, many of which are still in use today.

Third industrial revolution

Around the middle of the 20^th century, computers appeared on the scene. The Third Industrial Revolution saw the early development of factory automation and robotics. This era also saw the first use of computerised business systems that were built to manage and analyse data.

Fourth Industrial Revolution

Today, manufacturing is increasingly powered by information. Vast amounts of data come from across the business and around the world, in real time, around the clock. AI is at the heart of the Fourth Industrial Revolution, enabling manufacturers not only to gather all that data but also to use it—to analyse, predict, understand, and report. Industry 4.0 is not characterised by a single technology. It is defined by the seamless integration of a number of systems, tools, and innovations.

Fifth Industrial Revolution

We are now entering a fifth emerging phase that augments Industry 4.0 technologies by strengthening the collaboration between humans and robots.

Industry 4.0 technologies

Industry 4.0 solutions are built on nine technology pillars. These innovations bridge the physical and digital worlds and make smart and autonomous systems possible. Businesses and supply chains already use some of these advanced technologies, but the full potential of Industry 4.0 comes to life when they are used together.

1. Big Data and AI analytics: In an Industry 4.0 landscape, Big Data is collected from a wide range of sources. Of course, this includes capturing data from assets, equipment, and IoT-enabled devices. Data sources also extend beyond the factory floor, into other areas of the business and the world. They can include everything from customer reviews and market trends that inform R&D and design, to weather and traffic apps that help ensure smoother logistics. Analytics powered by AI and machine learning are applied to the data in real time—and insights are leveraged to improve decision-making and automation in every area of manufacturing and supply chain management.
2. Horizontal and vertical integration: An essential framework of Industry 4.0 is horizontal and vertical integration. With horizontal integration, processes are tightly integrated at the “field level”—on the production floor, across multiple production facilities, and across the entire supply chain. With vertical integration, all the layers of an organisation are tied together—and data flows freely from the shop floor to the top floor and back down again. In other words, production is closely integrated with business processes such as R&D, quality assurance, sales and marketing, and other departments—reducing data and knowledge silos and streamlining operations.
3. Cloud computing: Cloud computing is the “great enabler” of Industry 4.0 and digital transformation. Today’s cloud technology provides the foundation for most advanced technologies—from AI and machine learning to IoT integration—and gives businesses the means to innovate. The data that powers Industry 4.0 technologies resides in the cloud, and the cyber-physical systems at the heart of Industry 4.0 use the cloud to communicate and coordinate in real time.
4. Augmented reality (AR): Augmented reality typically overlays digital content onto a real environment. With an AR system, employees use smart glasses or mobile devices to visualise real-time IoT data, digitalised parts, repair or assembly instructions, training content, and more — all while looking at a physical object such as a piece of equipment or a product. AR is still emerging but has major implications for maintenance, service, and quality assurance, as well as technician training and safety.
5. Industrial Internet of Things (IIoT): The Internet of Things (IoT)—more specifically, the Industrial Internet of Things—is so central to Industry 4.0 that the two terms are often used interchangeably. Most physical things in Industry 4.0—devices, robots, machinery, equipment, products—use sensors and RFID tags to provide real-time data about their condition, performance, or location. This technology enables companies to run smoother supply chains, rapidly design and modify products, prevent equipment downtime, stay abreast of consumer preferences, track products and inventory, and much more.
6. Additive manufacturing/3D printing: Additive manufacturing, or 3D printing, was initially used as a rapid prototyping tool but now offers a broader range of applications, from mass customisation to distributed manufacturing. With 3D printing, parts and products can be stored as design files in virtual inventories and printed on demand at the point of need—reducing both costs and the need for off-site/offshore manufacturing. Every year, the scope of 3D printing becomes more diverse, increasingly encompassing base filaments such as metals, high-performance polymers, ceramics, and even biomaterials.
7. Autonomous robots: With Industry 4.0, a new generation of autonomous robots is emerging. Programmed to perform tasks with minimal human intervention, autonomous robots vary greatly in size and function, from inventory scanning drones to autonomous mobile robots for pick and place operations. Equipped with state-of-the-art software, AI, sensors, and machine vision, these robots are capable of performing difficult and delicate tasks—and can recognise, analyse, and act on information they receive from their surroundings.
8. Simulation/digital twins: A digital twin is a virtual simulation of a real-world machine, product, process, or system based on IoT sensor data. This core component of Industry 4.0 enables businesses to better understand, analyse, and improve the performance and maintenance of industrial systems and products. An asset operator, for example, can use a digital twin to identify a specific malfunctioning part, predict potential issues, and improve uptime.
9. Cybersecurity: With the increased connectivity and use of Big Data in Industry 4.0, effective cybersecurity is paramount. By implementing a Zero Trust architecture and technologies such as machine learning and blockchain, companies can automate threat detection, prevention, and response—and minimise the risk of data breaches and production delays across their networks.
