| 摘 要： | 比较4种基于斜率的灰色关联度模型,分析其优势与局限.以船舶碰撞事故中人为失误统计数据为例,应用斜率关联度与灰色斜率相似关联度模型进行计算,并将计算结果与邓氏关联度求取的结果进行比对.研究表明,斜率关联度及灰色斜率相似关联度模型不受因素序列值影响,也不受两序列间时序变化的特殊性影响;该两种模型应用于海事研究领域是可行、有效的.

| Abstract: | Four kinds of grey correlation models based on slope were compared,and their pros and cons were analyzed.Models of grey slope incidence and grey slope similarity incidence were applied according to the statistical data on human error in ship collision accidents,and the results were compared with other ones obtained by using the DengShi correlation model.Research shows that the models of grey slope incidence and grey slope similarity incidence are not influenced by the positive and negative of variable value... |
