基于遗传算法的城乡供水一体化管网优化设计研究OA

Carrying out the optimal design of water distribution networks under the constraints of consumer water demand and water pressure can effectively reduce pipeline system investment,which is of great significance to the improvement of economic and social benefits.Combined with an engineering example,this study establishes a mathematical model based on the genetic algorithm.Taking pipe diameter as the decision variable,water flow rate,water pressure,standard pipe diameter grades and flow velocity as constraint conditions,the model regards the minimum construction and operation costs of the pipe network as the objective function.The objective function is solved by genetic algorithm programming,and an optimized scheme for water distribution network design is obtained.Comparison of calculation results before and after optimization indicates that the genetic algorithm-based scheme can achieve remarkable cost savings with better economic efficiency.This study can provide a reference for the optimization of similar engineering projects.
