Research on Fire Risk Safety Evaluation of Tank Farm based on Improved Fuzzy AHP Method

摘要

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.
