Digital Twin

Virtual replica of a physical piece of equipment, process or plant that updates in real time with sensor data to replicate its behavior, state and performance. Enables simulation of operation and maintenance scenarios, predicting failures before they occur in the physical asset, optimizing process parameters and planning overhauls. Levels: descriptive (basic telemetry), diagnostic (root cause), predictive (future failure) and prescriptive (optimal action). Platforms: ANSYS Twin Builder, Siemens Teamcenter, GE Predix, PTC Creo. Key enabler of Maintenance 4.0.
