枚举法和遗传算法在农田灌溉管道系统优化设计中的应用

Application of Enumeration Method and Genetic Algorithms in Optimum Design of Irrigation Pipeline System in Farmland

大力推进节水灌溉技术,提高农业用水利用系数对缓解当前的水资源供需矛盾具有重要价值。文章以某灌区灌溉输水管道建设工程为例,建立非线性优化模型,利用枚举法结合遗传算法进行求解,最终得到最优设计方案。与原设计方案相比,输水管道总长度缩短约5.3%;灌溉供水成本降低约35.0%,具有显著的优化效果。

It is of great value to promote water saving irrigation technology and improve the utilization coefficient of agricultural water for alleviating the current contradiction between supply and demand of water resources.In this paper,the author,taking an irrigation water pipeline construction project in an irrigation area as an example,established a non-linear optimization model,solved the problem by combining enumeration method and genetic algorithm,and finally obtained the optimal design scheme.Compared with the original design,the total length of water pipeline is shortened by about 5.3%,and the cost of irrigation water supply is reduced by about 35.0%.The new scheme has significant optimization effect.
