20. Digital Twin Technology: A Paradigm Shift Towards Intelligent Systems

Digital Twin Technology (DTT) has emerged as a revolutionary approach that links the physical and digital worlds through real-time, data-driven replicas of physical entities. By integrating the Internet of Things (IoT), Artificial Intelligence (AI), big data, and cloud computing, digital twins provide predictive insights, operational efficiency, and lifecycle management across industries. This paper presents a comprehensive study of digital twin technology, including its conceptual foundation, architecture, applications, benefits, limitations, and future directions. The analysis demonstrates how digital twins are reshaping sectors such as manufacturing, healthcare, energy, and smart infrastructure, while also highlighting challenges in scalability, interoperability, and data governance.
