Universal exponential formula for underground water assessment base on immune evolutionary algorithm

在设定地下水各指标"参照值"基础上,提出了一个适用于多项指标的地下水水质评价幂函数加权加和型综合指数公式。采用免疫进化算法优化公式中的参数,得到优化后适用于任意多项指标的地下水水质综合评价的普适指数公式。该公式不受指标种类和数目多少限制,并把单指标指数评价公式作为特例包括在内。普适指数公式应用于多个实例分析计算,并与其他多种评价方法的评价结果进行比较,结果表明它形式简单、易于计算,具有可比性、通用性、实用性的特点。

By setting up benchmarks for underground water indices, a universal exponential formula with power function suitable to the multi-indexes is put forward to evaluate underground water. The immune evolutionary algorithm （IEA） is used for optimizing the parameters in the formula. The optimized formula is free from the restrictions of kinds and numbers of pollutant, including assessment formula of single index as a special example. It can be used for evaluating several eases, compared with the results of other methods, the modified universal formula is simple, easy to calculate, comparable and practical.
