The collaborative design of maritime structures involves not only multiple disciplines, but also uncertainty of information. Collaborative optimisation (CO) is a powerful multidisciplinary design and optimisation strategy known for its two-layer structure. In the original mathematical formulation of system-level optimisation, the second-level compatibility constraints are utilised. However, this makes

To improve the computational accuracy and efficiency of dynamic probabilistic analysis of complex structures, an extremum Kriging method (EKM) with multi-population genetic algorithm (MPGA) is proposed fusing extremum response surface method (ERSM), Kriging model and MPGA. Particularly, the EKM is developed by combining the Kriging model and ERSM to handle dynamic processes of related variables and
