of Tank Farm based on Improved Fuzzy AHP Method Qilei Wang, Benli Li, Xifeng Kang, Fang Zhang, Chunlei Jia, Xiaoming Zhang China People′s Police University Hebei Langfang, China 403115051@qq.com 基于改进模糊层次分析法的油罐区火灾 风险安全评价研究 王其磊,李本利,康习锋,张芳,贾春雷,张晓明 中国人民警察大学 河北 廊坊 065000 中国 403115051@qq.com Abstract-From the fire safety point of view, the impact factors and evaluation index of fire safety in tank farm are important to fire safety and fire rescue system. The tank farm fire risk assessment system was structured by multi coupling relationship of fire safety was integrated used and improved fuzzy AHP method was used in the fire safety evaluation, fire hydrant system,nitrogen cooling and evacuation system. Using expert scoring method to evaluate the index weight, and the original fuzzy analysis hierarchy model was improved. The results show that: the method reduces the weight of the evaluation subjectivity, and evaluate the overall effect is better, the results show that the model is reasonable and feasible. The improved fuzzy AHP evaluation method applied to fire risk evaluation of tank farm is practical and effective.
