摘　　要：分析了目前给水管网遗传优化研究仅考虑管网设计方案的经济性而忽略供水安全性的不足,采用罚函数的思想对遗传算法进行了改进,使其能够完成流量分配情况下的管网优化设计。实例计算对比了改进前后的设计方案,改进后设计方案的经济性和供水安全性得到了保证。Nowadays most of the genetic computed optimal designs ot water supplying networks are based on economical considerations and the safety factors are neglected. In this paper the genetic algorithm improved by penalty function theory is used, by this way the network is designed under condition of optimizing flow distribution. A case study compares the original plan with the revised one, and both the economic and safety factors are guaranteed by the revised plan.
