摘　　要：根据LNG加注站风险事故多层次、多因素及不确定的特点,结合行业安全标准规范,采用模糊综合风险评价方法确定了LNG加注站的风险因素和评价指标,建立了LNG加注站的安全评价体系。通过模糊运算求出评价总分,以达到风险辨识的目的。基于对运算结果的分析,针对该LNG加注站各项安全指标,提出了针对性的解决措施。模糊综合风险评价方法对LNG加注站安全状况的评价是有效的,减少了评价工作中的随意性,能较好地解决模糊、难以量化的难题,便于及时解决生产实际问题。In accordance with characteristics of LNG filling station risk accidents such as multi-level,multi-factor and uncertainty and based on industry safety standards,fuzzy comprehensive risk evaluation method is used to establish risk factors and evaluation indicators of the LNG filling station so as to build a safety evaluation system of LNG filling station.Total evaluation scores are obtained through fuzzy calculations in order to achieve the purpose of risk identification.Based on analysis of calculation results,targeted solutions are proposed for safety indicators of LNG filling station.The fuzzy comprehensive risk evaluation method can realize effective evaluation for the safety conditions of LNG filling station,which can reduce the arbitrariness in the evaluation and effectively solve fuzzy and difficultly quantized problems to facilitate timely solution to production problems.
