从长江洪水系统的特点出发，将该系统分解成３个目标明确的子系统，以子系统２为中心，建立了长江上中游防洪系统模糊优化调度模型，并提出了三峡水库洪水调度方案生成方法．以几个典型洪水年对模型及软件系统进行了模拟运行，表明系统具有较好的灵活性和可操作性 Based on the characteristics of the Yangtze River flood system, the system is decomposed into three distinct subsystems. Based on the subsystem 2, a fuzzy optimal scheduling model for the flood control system in the upper and middle reaches of the Yangtze River is established, and a method for generating the flood regulation scheme of the Three Gorges Reservoir . The model and software system are simulated and run in several typical flood years, which shows that the system has better flexibility and operability
