供水

Based on the principle of Markov process and multiobjective programming, a stochastic multiobjective dynamic programming model considering faced runoff prediction is developed for the optimization of generation and water supply at Danjiangkou reservoir. The reservoir will be used for water supply of the south-north water transfer project.
