摘　　要：建立了配水渠道流量优化调度 0 - 1线性整数规划模型。模型适用于支渠以下各级配水渠道在来水流量确定 ,分水渠道流量彼此相同且按“定流量、变历时”方式轮灌时的优化配水方案决策。并提出了各轮灌组引水时间均一化处理方法 ,使各轮灌组在同一引水时间结束灌溉 ,从而可使配水渠道进水闸能在同一时间关闭。A 0-1 linear integral programming model is created for optimal regulation of discharge in a distribution channel. This model is suitable for the decision of optimal distribution under the conditions of the intake discharge known, outlet flow for each second canal was remained constant with the rotational irrigation method of “fixed flow and varied time”. Also the method of treating same delivery time is proposed. Each rotational irrigation group is completed at the same delivery time and the intake gate of the distribution channel can be closed at the same time.
