摘要
因果图理论是可以进行故障分析的概率推理方法,但是缺乏对故障模式的重要性的分析。笔者在因果图理论中引入故障模式重要度概念,并成功运用于煤矿瓦斯爆炸的故障分析中。研究结果表明,基于因果图故障模式重要度的方法,是可以有效地进行故障诊断和安全分析的定性和定量的方法,能为事故预防提供可行的对策。
Causality diagram methodology is a probabilistic reasoning, which can be applied to fault analysis. However, it lacks analysis on the importance of failure mode. The importance of failure mode is introduced to develop causality diagram methodology, which is successfully applied in fault analysis of gas explosion in colliery. The study shows that causality diagram based on importance of failure mode is an effective qualitative and quantitative method to analyse faulty, evaluate system safety and provide feasible countermeasures to prevent accidents.
