四、流量分配流量在管网输入节点之间如何分配也是一个较难的数学问题.在后面应用动态规划方法寻找供水最佳流量分配方案中,分配越有规律,寻优就越容易,否则将给以后的寻优带来更多的问题,甚至可能导致失败.怎样才能有规律地分配输入总流量,应考虑两个因素,一是输入节点的编号应考虑输入节点处的地理位置、地面标高、管网形状等条件,二是流量在输入节点间的分配次序,如从输入流量大的节点至流量小的节点;从地面标高高的节点至低节点;由南至北或由东至西的输入节点间的顺序分配.
Fourth, how the flow distribution flow distribution between the input nodes in the pipe network is also a difficult mathematical problem. In the later application of dynamic programming methods to find the optimal distribution of water supply program, the more regular the allocation, the easier the search, otherwise it will To bring more problems to future optimization, and may even lead to failure. How can we regularly allocate the total input flow, we should consider two factors, one is that the number of input nodes should consider the geographical location of the input node, ground elevation , the shape of the pipe network and other conditions, and second, the distribution order of the flow among the input nodes, such as from the node with large input traffic to the node with small flow; from the node with high ground elevation to the low node; from south to north or from east to west The ordering assignment between the input nodes.
