最优化方法在给排水工程课程设计中的应用

The Application of the Optimization Method in the Course Design of the Water and Waste Engineering

随着社会经济的发展,城市给水排水管网系统的规模越来越大,如何设计和维护这样庞大的给排水管网系统,将从根本上影响着管网系统的投资及维护管理费用.基于严格数学模型的最优化法可使管网系统的设计更合理,因此,有必要在给排水工程课程设计的教学中,引入最优化的理论和设计方法,让学生在课程设计的实践中学会将最优化方法应用到给排水管网系统的设计中.该文介绍了如何用最优化法对教材中的实例进行设计,设计结果表明该方法的设计方案合理,可加深学生对管网系统设计本质的理解.

With the development of society economy, the scale of the water and waste pipe-network have become more and more large and the structure of the system is also more complex. How to design and maintain the large pipe--network will ultimately affect the system capital and maintained cost. The optimiza- tion method based on strict mathematic model can make the pipe--network design more reasonable. There- fore, it is necessary to introduce the theory and method of the optimization in the course design teaching of the water and waste engineering, so as to the students will learn this design method by practice. This paper presents an example with the optimization method, it can prove that the method is helpful for students to deepen understanding the essence of pipe--network design.
