摘要
为了建立一种对多项指标都能普遍使用的大气环境质量综合评价模式,利用模拟退火算法对幂函数加和型指数评价中参数进行优化,并用优化后的综合评价指数公式对大气环境进行综合评价。该公式应用于大量实例的分析评价结果与其他多种评价方法评价结果比较表明:该公式不受污染物种类和数目多少的限制,计算简便,具有可行性、实用性和通用性。
In order to set up a universal model available for multi-pollutant of air quality comprehensive assessment,the Simulated Annealing Algorithm was applied to optimize the parameters in assessment of power function of additive operation.The result of assessments from a lot of cases by applying this formula was compared with that by other methods.It showed that this formula was not limited by the sort and number of pollutants.It was a simple,feasible,practical and universal formula.
