一种新的方法已经开发出用于确定配水系统泵的最佳操作与水质的考虑。该方法是基于描述的操作作为一个离散时间的最优调度问题，可以用来确定分配系统中的泵的最优操作计划。解决方法是基于一个数学规划的方法，导致在一个大规模的非线性规划问题，不能使用现有的非线性代码解决。的优化问题的解决方案是通过接口的水力和水质模拟代码，EPANET，与非线性优化代码，GRG 2。约束的状态变量的约束被纳入目标函数使用增广拉格朗日罚函数法。在模型中使用了三个目标函数，以最小化（1）实际物质浓度与期望浓度值的偏差;（2）总泵持续时间;或（3）......
A new methodology has been developed for determining the optimal operation of water distribution system pumps with water quality considerations. The methodology is based upon describing the operation as a discrete time optimal scheduling problem that can be used to determine the optimal operation schedules of the pumps in distribution systems. The solution methodology is based upon a mathematical programming approach resulting in a large-scale nonlinear programming problem that cannot be solved using existing nonlinear codes. The solution of the optimization problem is obtained by interfacing a hydraulic and water quality simulation code, EPANET, with a nonlinear optimization code, GRG2. Bound constraints on the state variables are incorporated into the objective function using the augmented Lagrangian penalty method. Three objective functions were used in the model to minimize (1) the deviations of actual substance concentrations from desired concentration values; (2) the total pump duration times; or (3...
