水资源系统(地面水库、湖泊、地下水库等),由于目标函数呈非线性关系,因此导致问题的复杂性,通常采用动态规划解决具有序列性的决策课题,但常规的动态规划法不可能解决这种复杂的水资源运行问题(因维数灾)。本文基于微分动态规划法,提出一种较以往方法为佳的动态-非线性规划模型,并用以解决山东省半干旱地区多种水资源利用问题。计算结果表明了本方法的合理性和可靠性。 Because of the non-linear relationship between the objective function and the complexity of the water resources system (surface reservoirs, lakes, underground reservoirs, etc.), dynamic programming is usually used to solve the problem of sequence decision, but the conventional dynamic programming is impossible to solve This complex water resource operation problem (due to dimensionality disaster). Based on the differential dynamic programming method, this paper proposes a dynamic-nonlinear programming model that is better than previous methods and is used to solve the problems of various water resources utilization in semi-arid areas of Shandong Province. The calculation results show the rationality and reliability of this method.
