摘　　要：鉴于防洪在不同时段的重要性不同,提出将防洪时段划分为防洪重点时段和非重点时段的求解思路,通过灰狼算法提供动态规划算法寻优的边界条件,动态规划算法影响灰狼算法适应度值的双向反馈循环机制,形成了一种耦合动态规划与灰狼算法的防洪模型高效求解算法。对构皮滩水库极端、常遇2场洪水进行求解,与实际相比控制断面洪峰流量削减了42%、43%,求解耗时为19.54、71.27 s,同等精度下动态规划耗时为90~141、300~500 s,表明所采用的耦合算法兼顾了求解效率和精度,综合了动态规划与灰狼算法的优点,可以为水库防洪调度模型的求解提供新的方案。Based on the analysis of the importance of different time periods for flood control,this paper proposed a solution approach that segments flood control into key and non-key periods.An efficient solution algorithm for the flood control model that coupled dynamic programming and grey wolf algorithm was proposed through a bidirectional feedback loop mechanism,which used the grey wolf algorithm to provide boundary conditions for the dynamic programming,while the dynamic programming influences the fitness values of the grey wolf algorithm.The extreme and frequent floods of Goupitan Reservoir were solved.Compared to the actual situation,the peak flow of the control section was reduced by 42%and 43%.The time computation of the two scenarios was 19.54 s and 71.27 s,respectively,while that of the dynamic programming is 90~141 s and 300~500 s with the same accuracy.This indicated that the coupled algorithm balanced solution efficiency and accuracy by combining the strengths of both dynamic programming and grey wolf algorithm,providing a new solution for the flood control scheduling model of the reservoir.
