概括了流量分配优化设计方法的现状 ,并针对其不足提出了可用于多水源的简单易行的优化树法。这一最优化技术通过求得管网的最优树来使供水路径最短 ,从而使管网的总造价最小。它的应用对城市旧管网的改扩建也有着重要的意义 Summarizes the current situation of flow distribution optimization design method, and proposes a simple and feasible optimization tree method that can be used for multiple water sources according to its shortcomings. This optimization technique minimizes the total cost of the pipe network by finding the optimal tree of the pipe network to minimize the water supply path. Its application is also of great significance to the renovation and expansion of urban old pipe network
