本文介绍一种动态规划与模拟技术相结合的算法,用离散微分动态规划法(DDDP)进行择优计算,在状态转移过程中用模拟方法进行湖泊、河道、排水闸、抽排站等各项工程的水利计算。文中重点介绍了用分割法进行湖泊调节模拟计算的方法。这种算法可使数学模型较为逼真而且便于求解,在湖北省四湖地区除涝排水系统最优扩建规划中应用已取得满意成果。
In this paper, we introduce a dynamic programming and simulation technology combined algorithm, using discrete differential dynamic programming (DDDP) for the optimization calculation, in the state transition process using simulation methods for lakes, rivers, drainage gates, pumping stations and other projects Water calculation. The paper mainly introduces the method of dividing calculation for lake regulation simulation. This algorithm can make the mathematical model more realistic and easy to solve. It has achieved satisfactory results in the optimal expansion planning of drainage and drainage system in Sihu area, Hubei Province.
