| 摘 要： | 在缺乏足够可靠性数据的情况下,模糊故障树分析为研究矿井通风系统可靠性提供了重要途径.以完善的矿井通风系统构成为基础,用三角模糊数表示基本事件概率,以“矿井通风系统故障”作为顶事件构建矿井通风系统故障树(FTA),对通风系统可靠性进行研究,并将其应用于甘肃某矿.结果表明:故障树最小割集共549个,一级事件“监控反馈系统故障”是造成最小割集数量庞大的最主要原因；顶事件和一级事件可靠性较低,顶事件的失效模糊概率为(0.009,0.014,0.009),最大值达2.3％；监控反馈系统故障内基本事件模糊重要度最高,归一化最大值0.084 3,其余多分布于0.005 0～0.010 0范围内.

| Abstract: | In the absence of adequate reliability data,Fuzzy Fault Tree Analysis offers an important way for the study of mine ventilation system reliability.To study the reliability of mine ventilation system,the fuzzy Fault Tree Analysis(FTA) was established for a mine in Gansu,with triangular fuzzy number as basic-event occurrence rate and mine ventilation system fault as top-event,based on perfect system composition.The results show that the large number of minimal cut sets is high to 549 for the first grade event... |
