以供水管网微观模型为基础,综合考虑各种水质指标,采用自组织特征映射(SOM)网络和K-means算法对城市供水管网饮用水水质进行聚类分析。结果表明,水质综合评价方法可以综合考虑各种水质指标,克服了单一指标评价模型极端化、片面化的缺点,客观反映了管网中饮用水的水质状态。可见,利用SOM网络模型进行城市供水管网水质综合评价是可行的。
Based on the microscopic model of water supply network, considering all kinds of water quality indexes, SOM network and K-means algorithm were used to cluster the drinking water quality of urban water supply network. The results show that the comprehensive evaluation method of water quality can comprehensively consider various water quality indicators and overcome the shortcomings of extreme and one-sided evaluation of a single indicator model, objectively reflecting the water quality status of drinking water in the pipe network. Can be seen, the use of SOM network model for urban water supply network water quality evaluation is feasible.
