Abstract: Similar to the definition of the moment-independent importance measure on model failure probability, the authors define the moment-independent importance measure concerning the importance sampling method. After combining ...

Abstract: In this work, the fourth-moment method and the higher-order unscented transformation is combined to calculate the failure probability. The higher-order unscented transformation is used to efficiently estimate the first ...

Abstract: In this paper, a new approach is proposed to estimate the probability of failure in structural reliability analysis. This method is based on the law of total expectation and variance in subintervals, and it combines the ...

Abstract: For consideration of the wide applications of concordance and order information in global sensitivity analysis (SA), a new sensitivity index based on the spearman correlation coefficient (S-CC) is presented in this article. ...

Abstract: In this paper, a new fuzzy distance index is proposed to measure the effect of the fuzzy distribution parameters of random model inputs on the statistical characteristics of model output. First, the definition of the ...

Abstract: Sensitivity analysis is frequently considered an essential component in engineering design. In the design process of engineered structures, the output is implicitly related with the input variables. The Kriging model, one ...
