备注

针对供水管道漏损问题,基于以往研究,首先通过自组织网络(SOM)对样本漏损因素间的关联特征进行了仿真分析; 其次应用动态分级方法(DT)对管网漏损分类分级控制进行了研究,得到了不同分类数下的管道漏损分级; 最终将动态分级方法与系统聚类分析方法所得计算结果进行对比分析,结果表明动态分级方法在城市供水管道漏损控制方面研究的可行性,为城市供水管道漏损控制提供了新的方法与思路.

According to the leakage problem of water supply pipeline, based on previous research, the link between the influence factors and pipeline leakage were analyzed, and the leakage factors of samples were simulated through self-organization network(SOM); Dynamic classification method(DT)was applied to study the leakage control of water supply network, and different class number of the pipeline leakage were obtained, the results calculated by the dynamic classification were compared with system clustering analysis method, the conclusion are basically identical. The paper shows that the feasibility of dynamic classification method in the aspect of leakage control of water supply pipeline with the pipeline leakage classification more reasonable, provided a new method for leakage control of water supply pipeline.
