摘　　要：上游水库兼顾灌溉和防洪两项功能,面临着如何调度水量的问题。针对在一定时间(可分为n时段)内上游水库调度使其收益尽可能大的问题,从离线与在线两个方面进行研究。当每个时段来水量可提前预知时,建立了离线优化模型,采用动态规划方法求解;当每个时段来水量无法预知时,设计了最佳竞争比的在线策略并证明其是最优策略。Having the two functions of irrigation and flood control,the upstream reservoirs face the problem of how to schedule their water.The greatest possible scheduling benefits of the upstream reservoirs in certain time(which can be divided into n time intervals) are studied from the aspects of offline and online strategies.When the amount of water at each time interval may be predicted in advance,an off-line optimization model is established,and the available dynamic programming method is employed to solve it.When the amount of water at each time interval can not be predicted,an online strategy with competitive ratio of max{2,p′/p} is designed,which is proved to be the optimal strategy,where p′,p are the unit prices of irrigation and supply to the downstream respectively.
