Leveraging Virtual Commissioning for Digital Twins: An example case
Bibliographic record
Abstract
Virtual commissioning (VC) and digital twins (DT) are pivotal technologies in the Industry 4.0 (I4.0) landscape. However, their integration remains underexplored in the literature. This study proposes a structured methodology for optimising production line design and operation by integrating VC and DT. The proposed approach leverages two VC methodologies—Software-in-the-Loop (SIL) and Hardware-in-the-Loop (HIL)—to facilitate algorithm testing in both simulated and real-world environments. Bidirectional, real-time data exchange between virtual and physical models is established using OPC UA and RTDE protocols, creating a digital shadow that continuously updates to reflect the active system. The proposed framework promotes lifecycle-wide use of simulation models, enabling seamless reuse from VC to DT, while demonstrating the interactive potential of these technologies. Furthermore, the study highlights the advantages for companies in adopting both VC and DT to enhance operational performance.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
