Industry 4.0 is basically the fourth industrial revolution. After steam, electricity and information technology, Industry 4.0 involves the application of the Internet of Things (IoT) and other enabling technologies to all stages of industrial production and related processes (logistics, machine maintenance, occupational safety, final product quality, etc.). The analysis of Big Data produced by the interaction between machines, and between machines and the Internet, makes it possible to optimise production, reduce waste and work-related risks, and prevent malfunctions and failures.
