Applications, Value, and Challenges
Where digital twins earn their keep and where they struggle. This lesson covers predictive maintenance (the flagship use), applications across manufacturing, aerospace, energy, cities, and healthcare, the underlying value of experimenting safely in virtual space, and an honest account of the challenges: data, model drift, cost, security, and standards.
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.
