摘　　要：用水量预测研究和给水管网数学模型研究是优化调度的基础,用水量预测模型是在分析城市用水量序列数据模式的基础上,综合利用统计回归的方法建立的数学表达式;给水管网数学模型是建立水厂出厂压力和流量与管网测压点之间的经验数学表达式,它反映了给水系统的运行工况。优化调度模型的建立和求解是优化调度的核心。Primary coverage of urban water distribution system is introduced. Water consumption forecasting and mathematical model of water distribution network are the bases of optimal dispatching. Water consumption forecasting model is a mathematical representation which is based on the data pattern of urban water consumption series. Water distribution network model reflecting the operating mode of water distribution system is an empirical equation based on the relation of pressure, water flow and pressure tap＇ data. Derivation of optimal dispatching model is primary.
