摘要
利用灰色关联分析法,分析海事频数统计数据,将海上事故发生地点按与海事发生的关联程度进行排序,得出易发海事地点的降序排序为:港区、江河、海湾、航闸、航道与海峡、湖泊、海区、其他、运河、航道入口.比对一般的统计方法,灰色关联分析法可行有效.
This paper analyze the statistical data about the accidents' number at sea from the TSB(Canada) 1992,using the grey relational analysis,referring the correlation degree between the amount of accidents at sea and the sorts of sea area,then gives the conclusion,the areas tending to be accidents at sea are ranked from high to law: harbor area,river,gulf,navigation lock,channel,lake,sea area,rest,canal,channel entrance.Comparing with normal statistic methodology,GRA can overcome the chanciness defect,and it is reasonable and effective.
