突出环境效益的城市供水管网优化模型研究

Research on the Optimal Model of Urban Water Supply Network with Consideration of Environmental Protection

以节能降耗为主要目的,将环境效益作为供水管网优化的主要目标。在对多目标线性规划法进行分析的基础上,建立了突出环境效益的供水管网多目标线性规划模型,并利用Visual Basic语言进行编程求解。通过理论分析和算例研究,对模型实际应用价值进行验证。结果表明,突出环境效益的供水管网多目标线性规划模型在城市管网优化设计中,优化效果良好,适于在实践中推广。突出环境效益的优化模型是在城市供水管网优化设计中考虑环境问题的新尝试。

With consideration of environmental protection and energy efficiency, this paper emphasizes on the research of saving energy in the optimization of water supply network. Based on multi-objective linear programming method, a multi-objective linear programming model is established. The model makes fall use of the strong computational capability of computers. Visual Basic programs based on the multi-linear programming method in water supply system are developed. With theoretical analysis and engineering practice, it is showed that the multi-linear programming model is effective in practice and the performance is acceptable. The research is beneficial in connecting water supply network optimization with environmental protection.
