摘要
建立了一个基于经济性和可靠性的多目标数学模型用于给水管网优化设计。利用惩罚函数法对遗传算法进行改进后,应用其对多目标数学模型进行求解,并将该优化方法运用于实际工程。结果表明,采用多目标遗传算法得出的结果优于常规优化方法。
The muhi-objective mathematical model was established based on economics and reliability for the optimization design of water supply networks. The genetic algorithm was improved by penalty function method and the multi-objective mathematical model was solved. The optimization method was applied to actual project, and the results of this optimization were compared with the conventional optimization method in order to prove the superiority of the former.
