摘要
为了查找特定范围内对伤亡事故的发生有显著贡献的影响因素,建立了一种重点关注直接原因事件的新伤亡事故统计分析方法。确定了人、物、环境三个伤亡事故直接原因事件基础统计指标,并对三个指标按照对事故的贡献程度进行了分级;建立了基于多元方差分析的伤亡事故统计分析模型,采用假设检验的方法给出对伤亡事故发生具有显著贡献的直接原因事件类别。通过实例统计分析,说明了该方法的可行性和有效性。
In order to find out the factors which have significant impact on the occurrence of casualty accidents,a new accident statistical analysis method focusing on immediate cause incidents is established. And three immediate causes for casualty accidents which are people,material and environment factors are defined as basic event statistical indicators. The three indicators are graded according to their contribution degree to accidents. Statistical analysis method for casualty accidents based on multiple covariance analysis is established and hypothesis testing method is adopted to present the category of immediate causes which have significant impact on the occurrence of casualty accidents. Through statistical analysis on practical examples,the paper shows that this method is feasible and effective.
