摘要
给水管网设计中经常面临管径和管材的联合优选问题。针对传统管径优选技术的不足,提出了管材管径联合优化方法,改进了遗传算法的染色体编码方式,并以我国北方某县镇的供水管网扩建工程为例,对改进后的算法进行了应用。
The joint pipe size-material optimization problem is frequently encountered in the design of water distribution systems. With the deficiency of additional pipe size optimization technology, the method of joint pipe size-material optimization was put forward, a novel coding scheme and objective function of the genetic algorithm （GA） is proposed. The variables located in the GA chromosomes are of the type of string, instead of integer. The improved GA is applied into a real-world distribution network in a town in the north of China.
