Anatomy and Types of Digital Twins
What a digital twin is actually made of and the forms it takes. This lesson covers the virtual model (physics-based, data-driven, and hybrid), the data layer of sensors and pipelines that feeds it, the twin taxonomy from component to process scale, the fidelity-versus-cost tradeoff, and the sense-simulate-act loop that turns a model into a working twin.
What Is a Digital Twin?
A digital twin is a virtual replica of a specific physical thing, kept in sync by live data. This lesson defines it precisely, covers its three components, its origins with Michael Grieves and NASA, the crucial distinction from an ordinary simulation, and the digital model to digital shadow to digital twin taxonomy that pins down what 'twin' really means.
