灰色关联和层次分析法在加油站安全评价中的应用

Application of grey correlation method and analytical hierarchy process in safety evaluation of gas station

加油站安全系统是一个涉及多因素、多层次结构的非线性系统,可运用层次分析和灰色关联分析法对其安全状况进行分析。首先采用层次分析法得出评价指标权重,再运用灰色关联分析得出参评数据序列与标准数据序列之间的关联度,其中关联度最大值所对应的标准安全等级,即为加油站的安全等级。通过对加油站危险因素进行分析,建立了加油站安全评价指标体系。采用该方法对某加油站进行安全评价,得到其安全等级为Ⅱ级,评价结果与加油站实际运行状况相符。这表明该方法是合理有效的,能够为加油站的安全管理提供依据。

The safety system of gas station is a non-linear one involving in multiple factors and layered structures,its safety condition can be analyzed by grey correlation method and analytical hierarchy process(AHP).Firstly,AHP is used to obtain the weight of evaluation indexes,and then,the grey correlation method is used to analyze and get the correlativity between the referenced data and standard data sequences,in which the maximum correlativity corresponded with the standard safety level will be the safety level for gas station.The index system for safety evaluation of gas station was established by analyzing hazardous factors,and a safety evaluation for a gas station was made by this method.The results showed that the safety level for the gas station was Class II,which was in line with the actual operation status.Therefore,the aforementioned method was proved to be reasonable and effective,and it was a foundation for safety management of gas station.
