治水・利水を包含した貯水池操作に関する一考察

Abstract

Dam reservoirs must be operated for not only water quantity but also water quality. So, theaim of this study is to establish the optimal operation rule including flood, low flow and turbiditycontrols.At first, we propose the long term control policy synthesizing each objective by scalar optimiza-tion theory. Secondly, to deal with the increment of computer memory, total control periods aredivided into several sub-control periods. Then whole system is controlled through the proposedconnection methods such as 2-Step-DP, Iterated Method of DP and non-linear optimizationmethods among the optimal solutions of sub-control systems. Lastly, we compare above connec-tion methods in point of computer memory, computation time and the characteristics of controlledsequences.
