The first-order reliability method, (FORM), is a semi-
probabilistic reliability analysis
Reliability, reliable, or unreliable may refer to:
Science, technology, and mathematics Computing
* Data reliability (disambiguation), a property of some disk arrays in computer storage
* High availability
* Reliability (computer networking), a ...
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
Abraham Michael Hasofer (1927-2010) was an Australian statistician. Professor Hasofer held the position of the Chair of Statistics within the Mathematics Department in the University of New South Wales in Sydney from 1969 to 1991. He subsequentl ...
and Professor
Neil Lind 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
