| Bibliography: | 21-1344/T 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. LI Hai- yan1,JING Yuan- wei2（1.
