中文摘要：

为保障井下作业人员安全，对通风系统进行失效分析具有重要意义。针对矿井通风系统的复杂性、不确定性等特点，综合运用直觉模糊集建立通风系统失效可能性分析评价模型；为揭示模糊信息对评价结果的影响机理，采用直觉模糊加权集成算子（IFHGA）集成模糊信息，再借助博弈论确定组合权重；最后通过灵敏度分析比较3种距离算法下综合排序的稳定性，进而合理确定最优方法。结果表明，直觉模糊集对指标分值的处理结果更为准确，可应用于矿井通风系统失效可能性研究。

英文摘要：

In order to protect the safety of underground workers, failure analysis of ventilation system is of great signiticance. In view of the characteristics of complexity and uncertainty of mine ventilation system, the failure probability evaluation model of ventilation system was established by intuitionistic fuzzy sets. In order to reveal the influence mechanism of fuzzy information on evaluation results, the fuzzy information was integrated by intuitionistic fuzzy weighted aggregation operator （IFHGA）, and then the combination weights were determined by game theory. Finally, the stabilities of general orders under three kinds of distance algorithm were analyzed and compared by sensitivity analysis, so as to determine the optimal method. The results showed that the intuitionistic fuzzy sets had more accurate result on the index score, which could be applied to failure probability research of mine ventilation system.
