摘　　要：为有效预防高速列车乘客车厢火灾造成的人员伤亡和财产损失,采用直觉模糊集方法对CRH380A列车乘客车厢火灾风险进行评估。首先构建高速列车乘客车厢火灾风险评价指标体系;然后利用直觉模糊熵公式计算各指标因素的权重,得出“设备因素”所占的权重较大;最后利用直觉模糊加权几何算子将各指标因素权重与专家的评估结果矩阵进行信息融合,得出该列车乘客车厢火灾风险评价的等级为“很安全”。该评价结果符合实际情况,从而验证了该方法运用于高速列车乘客车厢火灾风险评估的可行性和可靠性。Once a fire accident breaks out in the passenger compartment of a high-speed train,it usually causes casualties and property losses.In order to effectively solve this problem,this paper uses the method of intuitionistic fuzzy set to evaluate the fire risk of CRH380Atrain passenger compartments.First of all,the paper builds an evaluation index system for passenger compartment fire risk.Secondly,the paper calculates the weight of each index factor by using the formula of intuitionistic fuzzy entropy,and figures out the proportion of equipment factor is larger.Then,according to the intuitionistic fuzzy weighted geometric operator, the paper integrates the index factors with the expert evaluation result matrix.Finally,it is concluded that the train passenger compartment fire risk assessment rating is very safe.The evaluation results are in line with the actual situation,and it is proved that the feasibility and reliability of the method can be applied to the effective assessment for the fire risk of passenger compartment in high-speed trains.
