Evolution at the Core of Digital Twin Engineering
Bibliographic record
Abstract
Engineering Digital Twins (EDT) presents a multifaceted challenge that extends beyond managing the lifecycle of a Digital Twin (DT) to include its continuous, dynamic interaction with the lifecycle of the actual object, system, or process it represents, referred to as the Actual Twin (AT). The relationship between the lifecycles of DT and AT necessitates a rethinking of the software development lifecycle of DTs. This vision paper examines the deeply intertwined lifecycles of DT and AT, arguing that effective methods for EDT must embrace the mutual and adaptive evolution of both over time. We propose placing evolution at the core of EDT. We identify key triggers of DT evolution, examine the engineering dimensions involved, and explore how the best practices, technologies, and tools of DevOps can support this evolution. Finally, we discuss current challenges and opportunities in the field. This paper serves as a call to action for the EDT community to adopt evolution as a crucial factor and core principle in EDT.

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.
