Firstly, the flood control regulation of TGP in Sep is computed based on the analyses on the inflow in Sep and Oct, and the risk and loss on the ahead impounding scheme is calculated and analyzed. Then, the storage level, power production and releasing discharge are achieved by computing on the electricity generation model through reservoir regulation graph. Thirdly, obstruction in channel is analyzed and the problem in the Chongqing reach is more serious in 175-145-155m scheme. The sediment aggrading process and distribution on different schemes is calculated by 1-D reservoir mathematical model. The navigation benefit is computed by navigation model. Based on above calculations, the impounding time is decided by the multi-purpose decision model, and evaluate by analytical hierarchy and balance layout model. A best impounding scheme is achieved to match the requirement of flood control electricity generation and navigation et al.

首先，在对宜昌站9、10月份来水分析的基础上，采用第2章建立的防洪优化调度子模型进行了三峡水库9月份防洪调度，分析了汛末提前不同天蓄水对防洪的影响，计算了汛末不同蓄水方案水库9月份的洪灾风险率和风险损失；接着，根据第2章建立的发电调度子模型进行了三峡水库发电调度计算，得出了不同蓄水方案下水库的坝前水位、发电量及下泄流量过程；然后，分析了175-145-155m方案下三峡水库的碍航问题，指出175-145-155m方案下重庆河段的碍航问题最为严重，通过进行不同蓄水方案下水库一维泥沙冲淤计算，得出了不同蓄水方案下库区淤积过程及分布，并通过航运调度子模型，计算了不同蓄水方案下水库的航运效益；最后，根据以上防洪、发电及航运调度计算的结果，运用第3章水沙多目标决策模型对水库的蓄水时间进行了多目标决策，并采用层次加权均衡规划模型对计算结果进行评价，得到一个能满足水库防洪、发电及航运各方面要求的最佳蓄水方案。
