农机事故关系因素的动态灰色关联分析

Research the Relation Factors of Farm Machinery Accident with the Grey Correlated Analysis

根据我国2007～2009年期间发生的农机伤亡事故统计资料,运用灰色关联分析理论,对影响我国农机安全事故的因素进行动态灰色关联分析,分别计算牌证管理与机具鉴定、违规驾驶、驾驶员驾龄、农机生产环境等4大因素中l5个子因素与农机事故伤亡人数的关联系数,深入分析事故成因与伤亡人数之间的动态灰色关联度,在众多的因素中辨识出主要的、影响大的因素,明确了因素间的主次关系,从而为研究和采取预防措施提供客观依据和指导。

According to the statistics of farm machinery accident during 2007-2009 in China,we use gray relational analysis to analyze factors which is related to farm-mechinery accident.15 correlation coefficients between factors and accident were calculated,such as license management and equipment identification,illegal driving,driving experience,driving environment and so on.By analyzing the gray correlation between accident causes and casualties,the main factors were identified,so we can provide objective basis and guidance for taking preventive measures.
