Definition
A digital twin is a virtual model of a specific real asset, continuously synchronized with that asset's actual condition and behavior through live data feeds, allowing simulation, monitoring, or scenario testing against a representation that reflects reality rather than only the original design. It is asset-specific and kept current, distinct from a static design model that does not update after commissioning.
Key facts
- Tied to one specific, real, physical asset, not a generic model or template of an asset type.
- Continuously updated with live data to reflect actual current condition, not a one-time snapshot at design or commissioning.
- Enables simulation and scenario testing (e.g., "what happens if load increases") against a model reflecting real behavior.
- Distinct from as-built documentation, which is a static record rather than a continuously live, synchronized model.
How does Digital twin work in maintenance?
A digital twin represents a specific physical asset in virtual form, continuously updated with live sensor and operational data so the model reflects the asset's actual current condition and behavior, rather than remaining a static representation of its original design intent.
What does Digital twin require?
As-built documentation is a static record of how an asset was actually installed, updated only when a deliberate documentation revision occurs. A digital twin goes further, continuously synchronizing with live data so the model tracks the asset's ongoing, real-time condition rather than a fixed point-in-time record.
FAQ
Frequently asked questions
What does a digital twin represent of a real asset?
It represents a specific real asset as a virtual model, continuously synchronized with its actual current condition and behavior through live data, enabling simulation and monitoring against that up-to-date representation.
