Julie Jebeile et al., « Verification and Validation of Simulations Against Holism », HALSHS : archive ouverte en Sciences de l’Homme et de la Société - notices sans texte intégral, ID : 10.1007/s11023-019-09493-8
(100 words) It has been argued that the Duhem problem is renewed with computational models since model assumptions having a representational aim and computational assumptions cannot be tested in isolation. In particular, while the Verification & Validation methodology is supposed to prevent such holism, Winsberg (2009, 2010) argues that verification and validation cannot be separated in practice. Morrison (2015) replies that Winsberg overstates the entanglement between the steps. The paper aims at arbitrating these two positions, by stressing their respective validity in relation to domains of application. It importantly argues for an increasing use of formal methods in verification, that makes disentanglement possible.
