Consider a system of many components with constant failure rate and general repair rate. When all components are reliable and easily reparable, the reliability of the system can be evaluated from the probability q of failure before restoration. In [14], authors give an asymptotic approximation by monotone sequences. In the same framework, we propose, here, a bounding for q and apply it in the ageing property case.
Résumé
Le calcul de la fiabilité d'un grand système réparable peut être réduit à celui de la probabilité q de panne avant remise à neuf. Dans [14], les auteurs donnent une approximation asymptotique de q par séquences monotones pour un système k/n. Nous proposons ici un encadrement de q dans un cadre plus général et l'appliquons à des réparations vieillissantes.
