Digital twins function in industrial applications by creating virtual replicas of physical assets, processes, or systems. These simulations enable real-time monitoring, analysis, and optimization of operations. By leveraging sensors and IoT technologies, digital twins provide insights into performance, predict maintenance needs, and enhance decision-making. Industries such as manufacturing, healthcare, and smart cities use digital twins to improve efficiency, reduce downtime, and innovate product designs. This advanced approach enhances operational clarity and controls, resulting in increased productivity and sustained competitive advantage.
