About book : The book is based on the syllabus of Industry 4.0 for the pre-final year engineering students of all disciplines of Gujarat Technological University, Gujarat. The first industrial revolution came with the advent of mechanisation, steam power, and water power, which the human learn then after followed by the second industrial revolution, which revolved around mass production and assembly lines using electricity. The third industrial revolution came with electronics, I.T. systems, and automation, which led to the fourth industrial revolution that is associated with cyber-physical systems. Generally speaking, Industry 4.0 describes the growing trend towards automation and data exchange in technology and processes within the manufacturing industry, including Internet of Thing (IoT), Industrial Internet of Things (IIoT), Cyber-physical systems (CPS), Smart manufacture, Smart factories, Cloud computing, Cognitive computing, Artificial Intelligence (AI) This automation creates a manufacturing system whereby machines in factories are augmented with wireless connectivity and sensors to monitor and visualise an entire production process and make autonomous decisions. The fourth industrial revolution also relates to digital twin technologies. These digital technologies can create virtual versions of real-world installations, processes, and applications. These can then be robustly tested to make cost-effective decentralised decisions. Industry 4.0 has already been demonstrated through business models such as offline programming and adaptive control for arc welding, taking the process from product design through simulation and onto the shop floor for production.
