A Digital Twin is a virtual replica of a physical object or system, like a machine, building, or even a city. It uses real-time data to simulate how the physical counterpart behaves, allowing for better monitoring and analysis. This technology helps businesses improve efficiency, predict maintenance needs, and enhance decision-making. By creating a Digital Twin, companies can test changes and scenarios without risking damage to the actual object. For example, a car manufacturer can use a digital twin of a vehicle to evaluate performance under different conditions. This innovative approach leads to smarter designs and improved products in various industries.
