基于AHP与GIS的供水管道风险分析研究
Research on Risk Analysis of Water Pipeline Based on AHP and GIS

随着经济的不断发展，管道的运行状况对人民日常生活愈发重要。本文以湘潭大学供水管道为例，分析湘潭大学供水管道可能存在的问题。依托层次分析法(Analytic Hierarchy Process, AHP)对供水管道故障的影响因素进行分析排序，本文得到了湘潭大学的供水管道故障的影响因素权重，同时本文以GIS为主要分析工具，通过网站获取某区域的管线图及相关管线数据，以此为数据源与AHP分析得到的供水管道故障的影响因素排序数据结合本文得到供水管道风险等级图，判断出可能发生故障的管道。本文采用AHP与GIS方法结合应用的方式得到供水管道风险等级图，可以为评定其他管道的风险等级、在管道出现故障时可以尽可能准确并快速地判断管道故障位置提供一种思路和方法。
With the continuous development of economy, the operation condition of pipeline is more and more important to people’s daily life. This paper takes Xiangtan University water supply pipeline as an example to analyze the possible problems of Xiangtan University water supply pipeline. Relying on the Analytic Hierarchy Process to analyze and rank the influencing factors of water pipeline failure, this paper obtains the influencing factor weights of the water pipeline failure of Xiangtan University, and at the same time, this paper takes the GIS as the main analytical tool, obtains the pipeline map of a certain area and the related pipeline data through the website, and uses this as the data source to analyze and rank the influencing factors of the water pipeline failure with the AHP. This is the data source and the AHP analysis of the influencing factors of water supply pipeline failure sorting data obtained in combination with this paper to obtain the risk level map of water supply pipeline, to determine the pipeline that may fail. This paper adopts AHP and GIS method to get the risk rank map of water supply pipeline, which can provide a way of thinking and method for assessing the risk rank of other pipelines and judging the location of pipeline failure as accurately as possible when the pipeline failure occurs.
