摘　　要：梯级水库调洪演算是“数字清江”工程中的重要内容之一,模糊优选动态规划方法是在动态规划求解的过程中采用模糊理论寻优的一种求取最优值的方法.文中给出了一种求解水库调洪演算的模糊优选动态规划模型(MDMFODP)的解法,讨论了模糊隶属度求解、动态规划寻优的具体实现.为解决MDMFODP模型在实际运用中出现的问题,提出了采用贪心算法求解方案.经过清江流域几次历史洪水资料数据的检验,计算结果表明该方法比利用常规调度方法具有更高的指标优异度、更长的调控时间以及更灵活的调度形式.The flood control operation of cascade reservoirs shall form an integral part of the project“Digital Qingjiang River”.Fuzzy optimization as well as dynamic programming(FODP)is a process of optimization based on fuzzy theory.The development of a model for optimizing flood control operation and dynamic programming by fuzzy theory is presented in this article.A con-crete method for obtaining fuzzy subordination degree and optimizing dynamic programming is discussed.Some solutions are proposed to solve the practical problems encountered in the process of the MDMFODP model application.It follows from the da-ta of several historical floods that the results obtained by this method have better quality indexes,longer operational duration and more flexible mode of dispatching.
