给水管网漏损检测周期的优化求解

城市供水企业迫切需要加强给水管网漏损管理,减少漏损水量,提高经济效益.给水管网检测周期的优化求解以管网历史漏损统计数据为基础,以漏损控制总费用最低为目标,采用自回归滑动平均混合过程及叠合模型预测管网漏水量、漏损件数,并求解管网经济漏水量,在此基础上建立漏损检测周期的优化数学模型.结果显示,总漏水量因实施优化检测周期而减少,漏损控制费用降低.优化检测周期的确定受管线检测费用、漏损水量费用等模型参数影响.

Optimal Solution to Inspection Interval for Water Leakage of Water Distribution Network

Water leakage management is required to minimize water loss and yields good economic returns for urban water industries. The solving procedure of optimal inspection interval was based on statistic data of water leakage,and its object was to minimize the total cost of water leakage control.Water loss and amount of water leakage were forecasted with autoregressive moving average(ARMA) model and supplementary model,and economic water loss was also estimated.Based on the above,the model to determine the optimal inspection interval for water leakage of water distribution network was established.The results indicated that water loss and the total cost of water leakage control decreased because of the optimal inspection interval.Its solution was effected by the parameters such as inspection cost,lost water cost,etc. in the model.
