改进的灰色理论法分析汽车火灾危险性

Automobile Fires Risk Assessment Based on Improved Gray Theory

分析诱发汽车火灾事故的各种因素,采用改进的灰色理论分析确定汽车火灾危险性评价模型,并计算各影响因素的权重。提出在传统灰色系统理论的基础上加入层次分析的手段,根据专家的评分结果,确定了各评价指标的灰色评价向量和权矩阵。以某款SUV车为例进行了火灾危险性评估,证明此方法在汽车火灾危险性评价领域具有可行性。

This paper analyzes the factors contributing to automobile fires,and the improved gray theory is applied to determine the risk assessment model and also to calculate the weights of every factors.It is pointed out that the hierarchy process is applied in the traditional gray theory and according to the assessment result of the experts,it is determined the grey evaluation vector of every evaluation index and the weight matrix.Taking an automobile SUV as the case to conduct fire risk assessment,it is testified that this method is feasible in car fire risk assessment area.
