The concept of Bayesian hypothesis testing is extended to system-level problems where full-scale testing is impossible. This paper shows how component-level validation results may be used to derive a system-level validation measure. This derivation depends on the knowledge of inter-relationships between component modules. The proposed methods are demonstrated for series and parallel systems. 000004828 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000004828 653__ $$aBayes factor, model validation, uncertainty. 000004828 7112_ $$a15th ASCE Engineering Mechanics Division Conference$$cNew York (US)$$d2002-06-02 / 2002-06-05$$gEM2002 000004828 720__ $$aRebba, Ramesh$$iMahadevan, Sankaran 000004828 8560_ $$ffischerc@itam.cas.cz 000004828 8564_ $$s351116$$uhttps://invenio.itam.cas.cz/record/4828/files/400.pdf$$yOriginal version of the author's contribution as presented on CD, . 000004828 962__ $$r4594 000004828 980__ $$aPAPER
