AWK-TIS: An Improved AK-IS Based on Whale Optimization Algorithm and燭runcated Importance Sampling for Reliability Analysis

In this work, an improved active kriging method based on the AK-IS and truncated importance sampling (TIS) is proposed to efficiently evaluate structural reliability. The novel called AWK-TIS inspired by RBF-GA previously published in literature. innovation of that TIS adopted lessen sample pool size significantly, whale optimization algorithm (WOA) employed acquire optimal Kriging model most probable point (MPP). To verify performance for reliability, four numerical cases which are utilized as benchmarks literature one real engineering problem about a jet van manipulate mechanism tested. results indicate accuracy efficiency method.
