摘　　要：提出基于故障树分析法、层次分析法、灰色聚类定权分析法的LNG加气站安全评价模型。建立LNG加气站安全性指标体系,运用层次分析法,通过专家评分的方式得出各指标层的权重;应用灰色聚类定权分析法,采用专家评分的方式,计算得出LNG加气站安全性得分。实例LNG加气站安全性得分为7.59。根据评价指标等级赋值,该加气站安全性较好,与该加气站实际情况相符。A safety evaluation model of LNG refueling station based on fault tree analysis,analytic hierarchy process and grey clustering weight analysis was proposed.A safety index system for LNG refueling station was established.The analytic hierarchy process was used to obtain the weight of each index layer through expert scoring.The grey clustering weight analysis method was used to calculate the safety score of LNG refueling station through expert scoring.The safety score of the example LNG refueling station is 7.59.According to the evaluation index level,the safety of the refueling station is good.It is consistent with the actual situation of the refueling station.
