配水管网设计优化研究

Research on Design Optimization of Water Distribution Pipe Network

在城市扩张和用水需求持续增加的背景下,城市配水管网更新优化已成为需要迫切解决现实问题。传统的优化设计方法是基于明确约束条件描述和问题,将实际管网优化问题抽象并转化为抽象数学问题求解,求解过程复杂及效率低。为获得具有成本效益的解决方案而进行的评估,本文采用启发式算法的设计算法,充分利用了管网设计中隐含的信息,获得满足需求节点的最小水头要求的成本有效的配置,并以具体管网为例进行了验证。结果表明,该算法分析耗时很短效率高,且对给水管网的最小费用设计具有较好的效果。

In the context of urban expansion and continuous increase in water demand,the update and optimization of urban water distribution pipe networks has become an urgent practical problem that needs to be solved.The traditional optimization design method is based on clear description of constraints and problems,which abstracts and transforms actual pipeline network optimization problems into abstract mathematical problem solving.The solution process is complex and inefficient.To evaluate the cost-effective solution,this paper adopts a heuristic design algorithm that fully utilizes the information implicit in the pipe network design to obtain a cost-effective configuration that meets the minimum head requirements of the demand nodes and uses A specific pipe network was taken as an example for verification.The results show that the algorithm takes a short time to analyze and has high efficiency,and it has good effect on the minimum cost design of water supply pipe network.
