Industry 4.0

Industry 4.0 is the name for the fourth industrial revolution: the integration of cyber-physical systems, industrial connectivity, data analytics and automation so that machines, products and business systems share information across the value chain.

The term Industrie 4.0 was introduced in Germany around 2011, when it was publicised at the Hannover Messe trade fair and adopted in the federal government's high-tech strategy. It follows mechanisation with water and steam power, mass production with electricity, and automation with electronics and IT. Its core idea is that physical equipment, products and software are linked through networks, so that data flows from the shop floor to planning and business systems and back, enabling decisions based on near real-time information.

Typical building blocks include connected machines and sensors, industrial communication standards such as OPC UA and MQTT, edge and cloud computing, manufacturing execution and enterprise systems, digital twins, analytics and machine learning, additive manufacturing and advanced robotics. Manufacturers pursue these to improve transparency, flexibility and quality, to make smaller batches and customised products economic, and to connect suppliers and customers through shared data.

In practice, Industry 4.0 is a gradual programme rather than a single technology purchase. Brownfield plants often retrofit sensors and gateways to older equipment, and interoperability, data quality, cyber security and workforce skills are common obstacles. Reference models such as RAMI 4.0 describe how assets, communication and business functions fit together, and the IEC 62443 series addresses security for industrial automation and control systems. Progress is usually judged with operational measures such as overall equipment effectiveness, quality and lead time.

Key points

The term Industrie 4.0 emerged in Germany around 2011 and refers to the fourth industrial revolution.
