Considering the electrovalence , the curve of water consumption and the reliability of water supply , this paper respectively sets up the model based on the maximal flux and the model based on the expectation flux . it takes yearly expenditure converting value and yearly cistern converting value as target function and takes continuity equation , velocity of flow and compression resistance of cast iron pipeline as restrictions and sets up the pga model on optimal design of water supply networks
考虑到峰谷电价、用水量变化曲线及用水可靠性因素的影响，分别建立了以最高时流量设计管网的模型和以期望时流量设计管网的模型，以年费用折算值加上清水池年造价折算值为目标函数，以连续性方程、管中流速和铸铁管耐压值等为约束条件，进行并行遗传算法对给水管网优化设计的实现。
