Connection between PTF, simulation and reality

PTF → Digital Twin (emulation) → Real machine → Data feedback → Optimized twin

1. PTF defines the formal structure: process, technology, function.

2. Digital Twin uses this data for simulation.

3. Real machine provides operational data (signals, parameters, events).

4. These data flow back into the model.

5. The twin gradually becomes "capable of learning" and improves its prediction accuracy.
