| Abstract_FL | Aimed at the computation complexity of multidisciplinary reliability optimization, reliability-based collaborative optimization method was studied to simplify the computation process. Considering that the sequential optimization and reliability assessment ( SORA ) carries out reliability analysis and deterministic optimization with the sequential cycle mode, the SORA-based collaborative optimization was presented. The presented method converts the 3-layer nested reliability optimization structure into sequential deterministic collaborative optimization and reliability analysis, which maintains the two-level structure of collaborative optimization and simplifies the computation process. At last, an engineering example is used to demonstrate the effectiveness of the presented method. |
