A virtual representation of a physical asset or process, synchronized with real-world data for monitoring, simulation, and optimization.
DESCRIPTION
Digital twins mirror physical systems using live telemetry, contextual models, and analytics. They enable monitoring, anomaly detection, scenario simulation, and predictive maintenance. Platforms provide modeling languages and graph-based relationships, integrating IoT, time-series storage, and AI. Twins scale from component-level to system-level and enterprise digital threads. Industry standards and taxonomies aim to improve interoperability. Digital twins reduce costs and improve reliability by testing changes virtually before deployment.
ALTERNATIVE DEFINITIONS
Wikipedia
A digital twin is a virtual representation that serves as the real-time digital counterpart of a physical object or process.
Emphasizes real-time synchronization with a physical counterpart.
Microsoft
Azure Digital Twins is an Internet of Things (IoT) platform that enables the creation of digital representations of real-world things, places, and business processes.
Defines digital twin capabilities within a managed IoT platform context.
Digital Twin Consortium
A digital twin is a virtual representation of real-world entities and processes, synchronized at a specified frequency and fidelity.
Provides formalized frequency and fidelity synchronization framing.
