Abstract:

The head and end water head constraints of the network in optimal design of traditional water supply network is not considered, so we put forward a mathematical model for optimizing the pumping tree pipe network with the objective function of lowest annual cost and the decision variables of the pump head, pipe length of standard diameter. In this model, assuming that the pump head is known, the pipe network optimization is transformed into linear sub-model of pipe network investment solution. The large system decomposition-dynamic aggregation method is applied to solve the sub-model. The research result shows that the method is feasible and effective for the optimization of pumping tree pipe network, which has some advantages in good search capability, fast calculation and high accuracy.
