The digital twin is the virtual representation of a physical object or system across its life-cycle. It uses real-time data and other sources to enable learning, reasoning, and dynamically recalibrating for improved decision making.” [1]

Digital Twin concept representation

Digital twins are realistic digital representations of physical things [3]

• A dynamic model of an asset, with the input of current performance data from the physical twin via live data flows from sensors; feedback into the physical twin via real-time control.
• A static strategic planning model of a system, with the input of long-term condition data from the physical twin via corporate systems; feedback into the physical twin via the capital investment process. [4]
