摘要
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.
A method of determining the optimum water supplying pattern (the lowest power pattern) for multiple input points networks is introduced here. From determining the topologic structure of networks, distributing the total flow capacity on the networks input points, calculating the networks and the liquid power state on every distribution to looking for the optimum water supplying pattern finally, every procedures are analysed and the calculating framegraphs are given. The dynamic programming theory is applied to the process for finding out the optimum pattern to transform from singlestage decision in large range to multistage decision in small range and to overcome the hand difficulty of the rough distributing precision for total flow capacity or the very long time calculation.
