Optimization and reliability of complex systems

RBDO (Reliability Based Design Optimization)

A method that combines optimization techniques and reliability calculations to take greater account of safety in the optimization concept.

Response Surface Method (RSM)

A method designed to explore the relationships between the dependent and independent variables involved in an experiment.

Probabilité de défaillance ; Failure probability

The probability of failure is the probability that the structure is in the failure domain.

Reliability index

This index is used to calculate the probability of failure, which is generally difficult to calculate; in the literature, there are several types of reliability index; the one used in this article is that of Hasofer and Lind....
