If materials or conditions change, existing metamodels may no longer be reliable. This paper presents an approach that uses model uncertainty, the Coefficient of Prognosis and the R <jats:sup>2</jats:sup> score to decide if a model should be reused or recalibrated, or if fine-tuning is needed. Two case studies show that the framework can provide sufficient recommendations and reused, recalibrated and fine-tuned models can match new models while reducing simulation and training effort. </jats:p> Cambridge University Press (CUP)2026 eng 2732-527X10.1017/pds.2026.10411 6527-536 J.-M.
