摘要

This paper presents a decision support methodology aimed at assisting Water DistributionnSystem (WDS) operators in the timely location of pipe bursts. This will enable them to react morensystematically and promptly. The information gathered from various data sources to help locatenwhere a pipe burst might have occurred is frequently conflicting and imperfect. The methodologyndeveloped in this paper deals effectively with such information sources. The raw data collected innthe field is first processed by means of several models, namely the pipe burst prediction model,nthe hydraulic model and the customer contacts model. The Dempster–Shafer Theory of Evidencenis then used to combine the outputs of these models with the aim of increasing the certainty ofndetermining the location of a pipe burst within a WDS. This new methodology has been applied tonseveral semi-real case studies. The results obtained demonstrate that the method shows potentialnfor locating the area of a pipe burst by capturing the varying credibility of the individual modelsnbased on their historical performance.
