Physical Asset: The Real-World Object or Process Being Replicated

The foundation of any Digital Twin is the physical entity it represents. This could be:

• A machine (e.g., an aircraft engine, a wind turbine, a robotic arm).

• A process (e.g., a production line, a logistics workflow).

• An environment (e.g., a city, a smart grid, an oil refinery).

The Digital Twin continuously receives real-time updates from its physical counterpart, allowing engineers and decision-makers to monitor and optimize operations remotely. 

IoT Sensors & Data Feeds: Capturing Real-Time Data

To replicate a physical entity digitally, real-time data collection is essential. IoT sensors and connected devices gather information on key parameters such as:
