基于集对分析的城市供水管网漏损预测及降漏研究

为了降低管网漏损水平，保障城市供水安全性和可靠性，以云南省某城市典型供水片区作为研究对象，运用集对分析漏损预测模型（SPA LF），从供水管网漏点数和漏点率两个方面分析了不同管材漏损的实际情况，预测未来不同管材的漏损趋势。该研究能够提高供水企业主动检漏水平与供水安全可靠性，降低管网漏损率与供水成本。

Study on leakage forecast and leakage reduction of urban watersupply pipeline network based on set pair analysis

In order to reduce the level of pipeline leakage and ensure the safety and reliability of urban water supply, this paper took a typical water supply area in a city of Yunnan as a research object. Using set pair analysis of leakage prediction model (SPA LF), the actual situation of the leakage of different pipe materials was analyzed from two aspects of the leakage quantities and the leakage rate of the water supply network, and the leakage trend of different pipe materials in the future was predicted as well, which could improve the level of active leak detection in water supply enterprises and the reliability of water supply safety, and reduce the leakage rate of pipe network and the cost of water supply.
