Abstract
Modern industrial systems are undergoing a transformative shift with the integration of Smart Manufacturing, Lean Six Sigma (LSS), Sustainable Industry Practices, Artificial Intelligence (AI), and the Internet of Things (IoT). These advanced methodologies are revolutionizing production engineering, improving operational efficiency, cost reduction, and sustainability. This paper presents a comprehensive analysis of these technologies, their synergistic impact on modern industrial operations, and their role in creating data-driven, autonomous, and efficient production environments. We explore the adoption of AI-driven predictive maintenance, IoT-enabled real-time monitoring, and Lean Six Sigma methodologies for waste reduction. Empirical analysis demonstrates cost savings, efficiency improvements, and enhanced product quality through the integration of these methodologies. The paper concludes with insights into future research directions, challenges in implementation, and recommendations for optimizing production engineering practices in Industry 4.0 and beyond.
