According to the AUVs' mission requirement of large operational depth, this paper provides a kind of ring-stiffened multiple intersecting spherical shell (RSMISS) for AUVs. In order to get the performance of the new shell, a surrogate-based optimization (SBO) method is proposed. The SBO method is employed to explore the kriging-based model. Simultaneously, a multi-start optimization approach is repeat-ed...
