Digital Twin

Definition

Digital Twin PlantDigital Twin is a virtual model of a real process, object or service.
The continue comparison between Digital & Physical Twins highlights deviations between predicted and real scenarios allowing to optimize the execution, operation and return of experience.

Digital Oil PlatformSupported by cyber physical system (CPS) technologies, Digital Twin is the first building block of the German Industrie 4.0 digital program.
In fact, Digital Twin main benefit is to aggregate different sources of data to enable a higher visualization and help making decisions.

In practice, the Digital Twin relies on the Fractal structure of the reference architecture model industrie 4.0 (RAMI 4.0) to connect things together. Working layer by layer, the Digital Twin will gather data from sensors to create the digital replica of an asset.

The Digital Twin can apply to a component, a tool, a machine, a process, a service, an entire plant enabling to build a digital plant from the agregation of each asset twin and finally to model the entire network connecting every virtual site.
The Digital Twin resulting from the consolidation of the data through the fractal structure of the Reference Architecture Model Industrie 4.0 of the network, from the smaller component to the entire plant, allows an analysis of the entire industrial ecosystem.

For assets management, Digital Twin can provide many information such as as-built characteristics, real-time status, running data, operational conditions, or position in a process. Meaning, Digital Twin is a solution to tackle many use cases:

  • Optimization of performance
  • Predictive maintenance
  • Remote monitoring
  • Running simulation
  • Change simulations

For processes and services, Digital Twin appears as a clear added value by enabling simulation of scenarios. Reducing risks of failure and forecasting benefits, Digital Twin is the secured and cost-effective way to perform feasibility studies in projects and to minimize downturns during operations in lowering costs and uncertainties.

In conclusion, Digital Twin is a strategic knowhow as it forms the first step to more efficient technologies such as machine learning and artificial intelligence, laying the foundation to connected products and services.
