改进遗传算法在环状管网水力平衡计算中的应用

Application of an Improved Genetic Algorithms in Hydraulic Distribution Calculation of Loop Pipe Network

标准遗传算法不擅于局部微调,在标准遗传算法的基础上,利用传统的优化方法中坐标轮换寻优方法对个体进行局部微调,寻优能力明显提高。把该算法用于环状管网水力平衡计算,计算结果精度较高。

SGA(simple genetic algorithm) is not well suited to perform finely tuned local searches. Based on SGA, in this paper,we find another way of local tuning method combined with traditional optimization way,and it turns out efficient. This method is applied to hydraulic distribution calculation of loop pipe network,and the results are finer.
