Digital twin

Definition

A digital twin is a virtual representation of a physical asset, process, or system that mirrors its real-time characteristics and behaviors. This technology integrates data from sensors and other sources to create a dynamic digital model, allowing for monitoring, simulation, and optimization of the physical counterpart throughout its lifecycle. Digital twins enable better decision-making by providing insights into performance, maintenance needs, and potential issues before they occur.
