摘要
以某市雾霾天气为例,找出导致该市雾霾发生的原因并建立相关的故障树,通过分析得出导致该市发生雾霾的主要原因为气象和人为原因.然后利用模糊综合评判法,对该市雾霾污染程度进行了量化评判,得出该市雾霾污染程度为重度污染,便于该市相关部门做好防范措施.结果表明,利用故障树分析法和模糊综合评判法对雾霾天气进行分析是可行的,为其他雾霾城市分析提供了参考依据.
By choosing fog-haze of a city and figuring out the causes of fog-haze weather,this paper established a fault tree.And the analysis revealed that it was mainly atmosphere and human beings that caused fog-haze weather.Then,this pa-per used fuzzy comprehensive evaluation to evaluate on the levels of fog-haze of the city,reaching the conclusion that it ranked general.So it was easy for the city to take precautions.The results show that it is feasible to analyze and evaluate the city’s fog-haze weather by fault tree analysis and the fuzzy comprehensive evaluation method.
