基于IAHP的市政供水管网爆管影响因素的权重分析

Weights analysis of influence factors for burst pipe of municipal water network based on IAHP

以广州市芳村市政供水管网2005-2010年的户外爆管维修记录为基础,运用统计分析方法深入研究管网爆损与管径、管材、管龄、爆管成因之间的关系。并采用改进层次分析法(IAHP)对芳村市政供水管网爆管影响因素进行权重分析,验证了用IAHP法确定爆管影响因素权重的可行性,得出各因素对芳村市政供水管网爆管事故的影响度排序和相对重要性权重值为:管材(0.4778)>管径(0.1937)>管道施工质量(0.1875)>管龄(0.0785)>外部施工破坏(0.0625)。

Based on the maintenance data of pipe bursts in Fangcun village municipal water supply net -work from 2005 to 2010 ,the paper studied the relationships between pipe burst and pipe diameter , pipe tube, pipe age as well as reasons of pipe bursts by use of method of statistics analysis .It applied improved analytic hierarchy process ( IAHP) to determine weights of influence factors of pipe bursts in Fangcun vil-lage municipal water supply network and verified the feasibility of determining weights of influence factors of pipe bursts by IAHP .The order of factors for pipe bursts in Fangcun village municipal water supply network is pipe material >pipe diameter>construction quality of pipe >pipe age>destruction of external construction and the corresponding weights of factors are 0.4778, 0.1937, 0.1875, 0.0785 and 0.0625 respectively .
