Digital twins are virtual simulations of physical objects and systems. They model the properties and behavior of these real-world objects and systems under specified conditions in real-time and transmit data to the real world via sensors. The objects and systems modeled by the twin can be material or immaterial, such as products, services, or processes. The latter may already exist in the physical world, or a digital twin can be created before they are physically built for planning and development purposes.
