Title: Computing conservative probabilities of rare events with surrogates
(Submitted on 26 Mar 2024)
Abstract: This article provides a critical review of the main methods used to produce conservative estimators of probabilities of rare events, or critical failures, for reliability and certification studies in the broadest sense. These probabilities must theoretically be calculated from simulations of (certified) numerical models, but which typically suffer from prohibitive computational costs. This occurs frequently, for instance, for complex and critical industrial systems. We focus therefore in adapting the common use of surrogates to replace these numerical models, the aim being to offer a high level of confidence in the results. We suggest avenues of research to improve the guarantees currently reachable.
