- A Digital Twin is a virtual representation of a physical object, system, or process, continuously updated with real-time data to mirror its real-world counterpart. It can range from simple component models to complex systems like smart cities, enabling insights into performance, predictive maintenance, and operational optimization. Originally conceptualized by NASA in the 1960s, digital twins became formally defined in 2002 by Dr. Michael Grieves for manufacturing applications.
- Key applications include manufacturing (process optimization), healthcare (patient-specific treatment simulation), construction (building management), automotive and aerospace (vehicle dynamics testing), and energy management (grid optimization). Despite their advantages, implementing digital twins poses challenges, such as data integration, computational demands, and standardization.
- The market for digital twins is rapidly expanding, driven by increased adoption across industries and advances in AI and the IoT, which enable more sophisticated simulations and decision-making capabilities. The global digital twin market is expected to reach $73.5 billion by 2027.

- A digital twin is a digital model of an intended or actual real-world physical product, system, or process (a physical twin) that serves as the effectively indistinguishable digital counterpart of it for practical purposes, such as simulation, integration, testing, monitoring, and maintenance. [1] A digital twin is 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 unexpected events observing and evaluating the operating profile system.[1] Though the concept originated earlier (as a natural aspect of computer simulation generally), the first practical definition of a digital twin originated from NASA in an attempt to improve the physical-model simulation of spacecraft in 2010. Digital twins are the result of continual improvement in modeling and engineering.
In the 2010s and 2020s, manufacturing industries began moving beyond digital product definition to extending the digital twin concept to the entire manufacturing process. Doing so allows the benefits of virtualization to be extended to domains such as inventory management including lean manufacturing, machinery crash avoidance, tooling design, troubleshooting, and preventive maintenance. Digital twinning therefore allows extended reality and spatial computing to be applied not just to the product itself but also to all of the business processes that contribute toward its production.
