The intersection of the Industrial Internet of Things (IIoT) and Artificial Intelligence (AI) represents a transformative shift in the landscape of industrial processes. This book will explore the synergistic relationship between IIoT and AI, examining how integrating networked devices, sensors, and advanced data analytics with intelligent algorithms can revolutionize industrial operations. This book will articulate a future where decision-making, automation, and predictive capabilities are significantly enhanced, leading to more efficient, responsive, and sustainable industrial environments. This book will explore how these technologies interplay to optimize processes, reduce waste, and improve overall efficiency in various industrial sectors. This book will combine scientific research and practical industry insights, providing recommendations for improving operational aspects such as energy use, maintenance schedules, and production efficiency. This book will address the critical part of sustainable architecture within the IIoT and AI domain, proposing environmentally responsible approaches to digital transformation in the industry. This includes considerations for energy-efficient system design, reducing carbon footprints, and promoting green technologies within industrial applications.
