区间数多目标多层次船型方案灰色优选法

Multi-objects and multi-layers grey evaluation method for the optimal selection of ship forms

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。本文根据船舶技术指标体系的层次结构特点,将层次分析法和灰色系统理论应用到船型方案的决策上来,提出了一种区间数多目标多层次的船型方案灰色优选方法,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。这一方法具有一定的理论意义和应用价值。

How to obtain the optimal choice from various ship forms is an important problem which the designers of ships need to research and solve.According to the characteristic of the technique index of ships,this paper applies the AHP and the grey system theory into the ship form evaluation,then puts forward multi-objects and multi-layers grey evaluation model for the optimal selection of ship forms.The result of an application example of this model indicates that the model introduced in this paper is effective and concise.It provides a reference for choosing a ship form reasonably.
