摘要
给水管网敷设后会因多种原因发生漏损,有效进行漏损控制是世界各国亟待解决的问题。在对某市实际管网漏损数据进行统计分析的基础上,建立了基于差分自回归移动平均模型[ARIMA(p,d,q)(P,D,Q)s]的管网漏损预测模型。该模型能够根据管网的历史漏损数据预测管网未来的漏损趋势,可为管网漏损控制及更新决策提供有效依据。
Leakage of water distribution network may be caused by several reasons. The effective control of leakage is a problem to be urgently solved for all the countries in the world. Based on the statistical analysis of leakage data of a city water distribution network, a prediction model for leakage of water distribution network was established based on autoregressive integrated moving average （ARIMA） （p, d, q） （P, D, Q） model. According to the historical leakage data, this model can predict the future leakage tendency of water distribution network, which can provide a basis for leakage control and renovation decision of water distribution network.
