遗传算法在排水管网优化中的应用研究

Research on application of Genetic Algorithms in Drainage networks optimal design

本文以某开发区的合流制排水管网设计为工程实例进行了深入研究,采用了近年来广泛应用于工程界的遗传算法。通过对基本遗传算法和改进的遗传算法在不同运算参数组合方案时的多次模拟实验结果进行比较,提出采用种群为25和最优保存策略时,由自适应交叉率和变异率组合构成的方案能够最迅速地收敛于最优解。

The rehabilitation and extension project of combined sewer system in certain Economic and Technological Development Zone is taken as a case study in this thesis. After comparing the simulation experiment results of different programs where varies of operation parameters are combined, the program, which consists of population size 25, character coding, elitism strategy, adaptive crossover and mutation rates, could converge the most rapidly in the optimal solution. Finally, the designed optimal sewer system is checked on its hydraulic reliability.
