需水量可累积的在线水库调度研究

Research on Online Reservoir Dispatch with Cumulative Water Requirement

针对未来时段来水量无法预知,庄稼的需水量可累积到未来时段,在当前必须做出决策供给水量,使得庄稼在整个生长期内灌溉收益尽可能大的问题,从在线与竞争分析的角度出发,设计最优策略——保守策略来调度水量,结果表明对于任意的来水量序列,该策略产生的收益不会小于最优收益的p′/p倍,其中p≥p′。

In order to solve the problem that the irrigation decision must be done so that the benefit of crops is maximized under the condition that the future inflow is unknown,the online strategy and competitive analysis are employed.The optimal-conservative dispatch strategy are designed to supply water to crops in every period.The result shows that the benefit of the strategy will not lower than the p/p′ times of the optimal benefit.
