Application of fuzzy comprehensive risk evaluation method in LNG filling station

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 calculationsin 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.
