A Method for Ship Compartment Layout Design Based on Gravitational Search Algorithm

A novel method for ship compartment layout design on multi-deck of one section of the hull was proposed,based on the design specification,statistical laws,conclusion of design experience and the related theory,and by using the utility theory and the improved multimodal optimization gravitational search algorithm based on the niche technology.The method can generate designs through the optimization calculation when noise,area and other parameters are inputted into it.The results from a series of optimization calculation tests show that the proposed design method are able to meet the requirements,and the improved gravitational search algorithm has a stable multimodal search capability.
