【Abstract】 The general principle and model of optimal operation in multireservoir flood control are analyzed. A linear programming is formulated for the optimal operation, two methods of replacing one kind of varibles with another are put forward for reaching the optimal solution of the model, and available conditions for the application of these two methods are described based on analyzing the advantages and disadvatages of the methods. a case study is presented, which shows the effectiveness and applicability of the linear programming.更多还原
