| 摘 要： | 目前大多数基于遗传算法的给水管网优化设计在供水安全性和经济性方面都存在不足。本文针对这些不足,对优化设计的目标函数进行了改进,加入了流速约束,提出了流量已初分配的给水管网多工况的优化设计,并采用罚函数法予以实现。最后对青岛市出口加工区管网进行了优化求解,通过优化结果的对比,验证了该设计方法的实用性及其在供水安全性和经济性方面的优点。

| Abstract: | The constraint condition of velocity is added to the objective function of the optimal design for water supply network to overcome the deficiencies of the current design method based on genetic algorithm.On this basis,a new design method for optimization of water supply network for multiple operation modes is proposed,in which the flow discharge is initially allocated.The method is realized by using penalty function theory.As a case study,the optimal design of water supply network for a district in Qingdao City is carried out.The advantages of the proposed method,including the economic benefit and water supply security are verified by the comparison with the result using current method. |
