1研究的必要性引滦工程是开发滦河水资源，向天津市和唐山市供水的大型水利工程。其供水系统由五座大型水库和六个供水区通过引滦入津、引滦入还、引还入徒三条大型输水渠道连接而成。运用系统工程理论和计算机技术，研究直接为调度部门使用的引滦供水实时代化调度决策支持系统 1 The Necessity of Research The Luanhe River Project is a large-scale water conservancy project that develops Luanhe water resources and supplies water to Tianjin and Tangshan. Its water supply system consists of five large reservoirs and six water supply areas that draw water from the Luan River to Tianjin and divert water from the Luan River into the water. It also leads to the connection of three large-scale water distribution channels. Using system engineering theory and computer technology, this paper studies real-time dispatching decision support system of water diversion from Luanhe River which is directly used by dispatch department
