摘要
在船舶碰撞受损研究方法的比较分析基础上,引入粗糙集属性约简方法.通过对船舶碰撞事故数据进行离散化处理,运用粗糙集理论构建船舶碰撞受损决策表模型,并利用粗糙集数据处理系统(RSES)得出约简集;根据约简集得出各因素对船舶受损的影响程度.对船舶碰撞受损有较大影响的因素作进一步分析,确定更容易导致船舶严重受损的因素.
Based on the comparative analysis of methods for ship collision damage,this paper introduces reduction methods based on rough set theory,and builds a model of the decision table and get the reduction set by rough set exploration system（RSES） by discretizing the ship collision accident data and using the rough set theory.And through which,the influence degree of various factors on the ship damage is obtained.Further research is carried out on those important factors so as to find which is more likely to lead ship severely damaged.
