Digital twin

Uncommon card · No. 82229

A digital twin is a computational model of an intended or actual real-world physical product, system, or process (a physical twin) that serves as a digital counterpart of it for purposes such as simulation, integration, testing, monitoring, and maintenance. By its strict definition, a digital twin is distinguished from an ordinary simulation in that it continuously uses real data from its physical counterpart to dynamically synchronize with the real system. A model that operates without data from its physical counterpart may also be described as a digital twin, but this is considered an overly broad and largely marketing-oriented interpretation of the concept. A digital twin is "a set of adaptive models that emulate the behaviour of a physical system in a virtual system getting real-time data to update itself along its life cycle. The digital twin replicates the physical system to predict failures and opportunities for changing, to prescribe real time actions for optimizing and/or mitigating...
