Cyber manufacturing is a concept, research field, and methodological approach focused on the deep integration of computational, communication, and control systems across all stages of the manufacturing lifecycle. It investigates the architectures, technologies (such as IoT, AI, and digital twins), and operational paradigms required to create highly interconnected, intelligent, and agile production environments capable of autonomous decision-making, real-time optimization, and distributed control, signifying a fundamental transformation towards resilient, flexible, and efficient manufacturing systems.
