本文介绍了第二个系列的三个模型的多水质供水系统的优化调度。第二个模型被称为Q-H（流量水头）模型，旨在确定泵和阀门的最佳操作，而不考虑水质方面。然而，该模型属于多质量系统的三模型组，因为它是全低质量水头（Q-C-H）模型的两个构件之一（另一个是流量-质量Q-C）。该Q-H模型基于泵站的水头流和功率流函数的连续表示，这反过来又导致连续的非凸优化模型。对于给定的网络流量分布Q 0，求解Q 0-H模型，以实现泵和阀的最优运行。然后通过改变圆形流来修改流量分布，使用投影梯度法结合复形法，复形法采用Q 0-H解的结果，使得下一点处的局部最优解具有更好的目标函数值。继续该过程，直到满足终止标准之一。因此，循环流在外部问题中充当决策变量，而在内部问题中，决策是泵和阀的操作。该方法被证明是通过应用到一个样本问题。
This paper describes the second in a series of three models for optimal operation of multi-quality water supply systems. This second model, which is termed the Q-H (flow-head) model, seeks to determine the optimal operation of pumps and valves, and does not consider water quality aspects. However, the model belongs to the group of three models Tor multi-quality systems because it is one of the two building blocks (the other is the flow-quality Q-C) of a full-llow-quality-head (Q-C-H) model. This Q-H model is based on continuous representations of the head-flow and power-flow functions of the pumping stations, which in turn results in a continuous non-convex optimization model. For a given flow distribution in the network, Q0, the Q0-H model is solved for the optimal operation of pumps and valves. The flow distribution is then modified by changing the circular flows, using a projected gradient method combined with the Complex Method which employs the results of the Q0-H solution, such that the locally optimal solution at the next point has a better value of the objective function. The process is continued until one of the termination criteria is satisfied. The circular flows thus serve as decision variables in an external problem, while in the internal problem the decisions are the operation of pumps and valves. The method is demonstrated by application to a sample problem.
