This paper presents the implementation and application of a modified particle swarm optimization
(PSO) method with dynamic adaption for optimum design of a battleship strength deck subjected to non-contact
explosion. The numerical simulation process is modified to be more computationally efficient so that the task
is realizable. The input variables are the thickness of plates and the dimensions of stiffeners, and the total
structural mass is chosen as the fitness value. In another case, the response surface method (RSM) is introduced
and combined with PSO (PSO-RSM), and the results are compared with those obtained by the traditional PSO
approach. It is indicated that the PSO method can be well applied in the optimum design of explosion-loaded
deck structures and the PSO-RSM methodology can rapidly yield optimum designs with sufficient accuracy.
