A structural reliability-based sensitivity analysis method using particles swarm optimization: relative convergence rate [PDF]

Journal of Zhejiang University-SCIENCE A, 2016
This paper proposes a novel reliability-based sensitivity analysis (SA) method, namely relative convergence rate of random variables using particles swarm optimization (PSO). The convergence rate of a random variable during the optimum evolution process reflects the sensitivity of the objective function with respect to the random variables.

Metamodel-based importance sampling for the simulation of rare events

, 2011
In the field of structural reliability, the Monte-Carlo estimator is considered as the reference probability estimator. However, it is still untractable for real engineering cases since it requires a high number of runs of the model.
