摘要
如何从多种船型方案中正确选择出一种最佳方案,一直是船舶设计人员需要去研究和解决的一个重要课题.文中根据船舶技术指标体系的层次结构特点,将灰色系统理论应用到船型方案的决策上来,提出了一种多目标、多层次的船型方案灰色优选理论模型,以低层次的输出作为高层次的输入,对每一层次的单元系统进行优选计算,最后利用总的关联度进行排序,对船型方案进行优选.实例应用结果证明该方法使用简便,切实可行.
How to obtain the optimal choice from various ship forms is an important problem which ship designers need to research and solve. According to the characteristic of the technique index of ships, the grey system theory is applied to the ship form e.valuation. A grey optimal choice is put forward for the projects of ship forms with multi-objects and multi-layers. Each layer cell system is calculated by inputting the output of the lower into the higher. Lastly, by means of the grey relational grade, sequence of all schemes is arranged and the optimal selection for ship forms is performed. The result of an application example indicates its effectiveness and conciseness. It provides a reference for choosing ship forms reasonably.
