基于GIS的供水爆管隐患评价及维护决策
|
摘要
通过地理信息系统对城市供水爆管隐患评价及维护决策,为供水企业科学管理提供分析和决策功能。首先运用层次分析法,对爆管影响因素评价指标进行总排序,计算每个指标的重要性权值,建立爆管隐患评价模型,根据评价等级进行初步维护决策;对初步决策需要维护的管段,在建立检测费用、维护费用、破坏费用等函数的基础上,建立维护决策模型,从而决策是否维护,以及采取哪种维护方案。在地理信息系统中运用爆管隐患评价模型及维护决策模型,可以减少维护费用及爆管事故损失费用。
Through the evaluation and maintenance decision about the urban water supply pipe burst hidden trouble from the GIS,provide analysis and decision function to the water supply enterprise for scientific management.First,use AHP(Analytical Hierarchy Process) to total the evaluation quotas about the factors of pipe burst,calculate the important weight of each quota,establish the evaluation model of pipe burst hidden trouble,according to the evaluation level to do initial maintenance decision;the initial decision needs which pipe should be maintained,on the basis of test cost function,maintenance cost function,damage cost function and so on,establish the maintenance decision model,to decide to maintain,or else,and take which maintenance program.Use the evaluation model of pipe burst hidden trouble and the maintenance decision model in GIS,may reduce the maintenance cost and the pipe burst accident cost.
