多ダム・多評価地点系の最適操作に関する研究

Abstract

The aim of this study is to establish an optimal operation procedure for water quantity controlsystem with multi-reservoir and multi-defence point. That is to say, the complexity varies directlywith the number of reservoirs and defence points, since they add other variables to the problem.So, introducing the decomposition method, we divid the original system into several subsystemsand total system is optimized by synthesizing the optimal solutions of subsystems. The advantageof this approach is the reduced amount of the computer memory and the shortened computationtime. Moreover, the application of Dynamic Programming in subsystem permits to use the non-linear criterion function and regulates the sequences of the controlled flow passing through thedefence point.Those approaches are applied to the dam operations system in Yodo River.
