On the possibility of the utilizing polynomial chaos expansion for reliability-oriented sensitivity analysis
Original language description
The paper is focused on fast and efficient method of estimation of reliability-oriented sensitivity indices using Polynomial Chaos Expansion (PCE). It is shown that once the approximation of limit state function is created, it is possible to obtain condi-tional failure probabilities and sensitivity indices directly from PCE without any additional computational demands. The proposed approach is applied on fundamental numerical example with known reference solution and its efficiency and accuracy is discussed. Two reliability-oriented sensitivity indices directly oriented to the failure probability are estimated and compared. The comparison is performed on a interval of failure probability from zero to one. PCE has proven to be an effective tool for estimating sensitivity indices, especially for low probabilities of failure.
