- The first-order reliability method, (FORM), is a semi-probabilistic reliability analysis method devised to evaluate the reliability of a system. The accuracy of the method can be improved by averaging over many samples, which is known as Line Sampling. The method is also known as the Hasofer-Lind Reliability Index, developed by Professor Michael Hasofer and Professor in 1974. The index has been recognized as an important step towards the development of contemporary methods to effectively and accurately estimate structural safety. The analysis method depends on a "Most Probable Point" on the limit state (en)
- La méthode FORM-SORM est une méthode utilisée en fiabilité pour déterminer la probabilité de défaillance d'un composant.
* FORM est l'acronyme de First Order Reliability Method, méthode de fiabilité du premier ordre ;
* SORM est l'acronyme de Second Order Reliability Method, méthode de fiabilité du second ordre. Il s'agit de trouver le point de conception, c'est-à-dire le cas de défaillance du maximum de vraisemblance. La solution est obtenue par une procédure d'optimisation. (fr)
