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。
In order to ensure the safety of downhole workers, it is of great significance to analyze the failure of ventilation system. In view of the complexity and uncertainty of mine ventilation system, an intuitionistic fuzzy set is used to establish the evaluation model of the probability of failure of ventilation system. In order to reveal the influence mechanism of fuzzy information on evaluation results, an intuitionistic fuzzy weighted integration operator (IFHGA) Integrated fuzzy information, and then use the game theory to determine the combined weight; Finally, the sensitivity of the three kinds of distance algorithm to compare the stability of the comprehensive ranking, and then determine the optimal method reasonably. The results show that the intuitionistic fuzzy set is more accurate for processing the index scores and can be applied to the study of mine ventilation system failure probability.
