摘要
在模糊环境下,基于可能性理论,针对机动车尾气对城市空气污染造成的影响,建立了给定置信水平下的最大空气污染物含量模型,并给出了模型的算法,最后通过廊坊市机动车监测数据计算出实际污染物含量和在给定置信水平下的机动车最大污染物含量,通过比较验证了算法的可行性。
A model with the given confidence level is established to cope with vehicle exhause emission in air pollution of city,which based on possibility theory in fuzzy. Then,an algorithm is proposed to deal with the model. Finally,the feasibility of the algorithm is tested through a numerica example,which compared with the actual content and calculated content by the monitoring data of motor vehicle in Langfang.
