摘要
本文采用年费用最小经济比较准则,利用动态经济分析的方法,考虑资金的时间价值,分析不同时期投资、运行费对管网优化计算的影响,导出了用动态经济分析的年费用法的管网费用函数的数学模型和经济管径的计算公式。
A mathematical model of cost function of water supply pipelines network and the formula of ecomomic tube diameters of the popetime network are introducted by research of the relationsh between the investments in different period, operation cost and the optimal tube diameters. In the model, the criterion of minimum annual cost is adoptde and the time value of money is considered.
