Intelligent Decision Support System of Ship Unsinkability Design in the First Design Stage

If the ship is damaged, we should try our best to guarantee its unsinkability. Ship unsinkability is one of the most important aspects of ship survivability. The intelligent decision support system of ship unsinkability design in the first design stage is founded in this paper. The intelligent decision support system consists of two main functions. One is manual ship unsinkability design and the other is intelligent ship unsinkability design which is introduced in detail in this paper. The survival probability calculation model, ship unsinkability mathematic optimization model and intelligent optimization arithmetic corresponding to the mathematic optimization model are founded in the intelligent decision support system. The gene arithmetic is improved in the intelligent optimization arithmetic. The gene sequence is defined based on the tradition gene definition. The chromosome defined in this paper can be considered as a special chromosome of which gene sequence is ordered. At last, design cases are given to explicate how the intelligent system helps in ship unsinkability design jobs.
