摘    要:采用对遗传算法中的基本操作进行控制的思路,提出对传统遗传算法改进的方法,并且将其与城市燃气管网的水力计算相联系,以解决城市管网改造工程中存在的问题。同时,结合MATLAB语言对算法的基本操作加以说明,使优化算法更加直观,易于理解。通过对遗传算法基本过程的控制,有效地实现了水力计算的目的,管网的可靠性较以往手工计算或传统的遗传算法的结果有较大提高。利用改进的遗传算法能够实现对管网改造项目的优化设计,为设计研究带来便利且准确性提高。

Abstract:

The ideas of improved traditional methods of genetic algorithm were put forward through the way of controlling the basic operations. In order to solve these project problems, the method was associated with the hydraulic calculation. Moreover, for the purpose of making the algorithm more intuitive and easy to be understood, the basic operations with MATLAB were illustrated. The improved genetic algorithm can achieve the optimal pipe network design in reconstruction projects, which is also convenience to design and research.
