摘要
目前基于遗传算法的给水管网优化模型存在很多缺陷,为提高其实用性,对优化模型进行了改进。在约束条件中,用流量约束代替最小管径约束,并加入了流速约束。在此基础上,采用罚函数法对目标函数进行改进,实现了给水管网多工况优化设计。通过实例计算对比了各种设计方案,验证了改进后的优化模型在供水安全性和经济性方面的优越性。
The present optimization model for water supply network based on genetic algorithm has some deficiencies. Therefore, the optimization model was improved to enhance its practicability. The minimal pipe size constraint is replaced by the flow constraint, and the velocity constraint is added to constraint conditions. On this basis, multi-mode optimal design of water supply network is realized through objective function improvement using penalty function theory. The superiority of the improved optimization model in security and economy aspects is verified through comparison of various design plans.
