Digital twin - Wikipedia

A digital twin is a digital replica of a living or non-living physical entity.[1] By bridging the physical and the virtual world, data is transmitted seamlessly allowing the virtual entity to exist simultaneously with the physical entity. Digital twin refers to a digital replica of physical assets (physical twin), processes, people, places, systems and devices that can be used for various purposes.[2] The digital representation provides both the elements and the dynamics of how an Internet of things device operates and lives throughout its life cycle.[3] Definitions of digital twin technology used in prior research emphasize two important characteristics. Firstly, each definition emphasizes the connection between the physical model and the corresponding virtual model or virtual counterpart[4]. Secondly, this connection is established by generating real time data using sensors. Digital twins integrate internet of things, artificial intelligence, machine learning and software analytics with spatial network graphs[5] to create living digital simulation models that update and change as their physical counterparts change.
