摘要
以某输水管网为例,采用动态规划法对其进行优化。以管网年折算费用最小为目标函数,以节点水压等为约束条件,用枚举法对备选管径进行优选,使目标函数取得最小值的那一组即为最优管径。使用最优管径设计管网比优化前投资成本降低11.49%,优化效益显著。
With a water-supply network by dynamic programming. The minimal as an example, the network was optimized annual discounted costs were taken as an objective function and node pressure etc. as constraint conditions. The alternative pipe diameters were optimized as per enumeration method and the group allowing objective function with the least values would be the optimized one. It is proved the optimized pipe network reduced by 11.49% in terms of cost and the optimized ben- efits proved much significant.
