基于面向对象技术的给水管网设计程序优化

针对城市给水管网模型组成各部分的特点和相互之间的联系,基于面向对象的类层次关系进行优化设计程序的开发,将遗传算法作为一个假想类,与管网整体类及管网各要素类有机地融合在一起.所编制的应用程序包括数据输入输出模块、管网水力计算模块和遗传算法优化模块三部分.以我国沿海某新建开发区大型管网为实例,采用所编制的程序进行优化计算,结果表明,该程序可使给水管网年费用折算值降低,具有良好的实用效果.

Programming development and application for optimum design of water distribution network based on object-oriented technology

Based on the characteristics and connection among components of water supply network model,a set of object-oriented classes hierarchy is designed;they syncretize the genetic algorithms together with the whole network class and its components classes as an imaginary class.It is proposed that genetic algorithm can be applied to large-scale water supply network optimum design.Also,an application program is developed including data input and output modules,hydraulic calculation module and genetic algorithm optimization module.A new development zone's network in East China is optimized by the program as a case study;and the network's annualization of expense is reduced.Optimization results show that the program has a good practical effect.
