给排水管道经济综合评价及塑料管道产量预测

通过对常见给排水管道的技术性能、应用、施工经济性的分析,结合矩阵分析法对各种管道进行经济性综合评价,同时,结合最小二乘法,对新型塑料给排水管道的发展进行定性、定量的分析、预测。结果表明,塑料管道的年产量随时间成指数关系增长,在越来越多的市政给排水管道工程中得到推广应用。

Comprehensive economic rvaluation of water-supply pipes and drainpipes and productivity forecast of plastics pipe

Through analyzing and comparing different pipes for water supply and water drainage on technique function,application,construction,economic and other aspects systematically. Combing Matrix analytical method different pipes were economically evaluated. The development trend of new developed municipal engineering pipes were analyzed and predicted by least squares algorithm,the result shows that the output of plastic pipe conforms to exponential function with the time. It would be popularized and applied in mo...
