Comparison of Statistical and Machine Learning Models for Pipe Failure Modeling in Water Distribution Networks

Abstract: The application of statistical and Machine Learning models plays a critical role in planning and decision support processes for efficient and reliable Water Distribution Network (WDN) management. Failure models can provide valuable information for prioritizing system rehabilitation even in data scarcity scenarios, such as developing countries. Few studies have analyzed the performance of more than two models, and examples of case studies in developing countries are insufficient. This study compares various sta… Show more

“…However, ensemble models significantly improve accuracy (Hastie et al 2009) but are computationally expensive. With computational advances and quicker processing speeds, ensemble methods are more common and have shown better accuracy, even compared to several other data-driven pipe failure models (Chen et al 2017;Giraldo-González & Rodríguez 2020). Tree ensemble models are simple in their approach and do not require mathematical pre-processing steps, and for this reason, they are an attractive machine learning models that is easily accessible (Winkler et al 2018).…”

“…Finally, this result attained by our study is compared with those obtained in two previous ones (Table 5). In [2], an ANN (among other models) is used to predict pipe failures in a medium-sized Colombian city. The model is independently applied to asbestos cement and PVC pipes.…”

“…Intelligent predictive systems are models and algorithms that provide valuable information about the future performance of a system, serving as support for decision-making. In a recent study [2], researchers compare the performances of statistical models predicting failure rates in groups of pipes and machine-learning algorithms forecasting individual pipe failure rates. This work includes some of the most popular statistical models, as linear regression, Poisson regression and Evolutionary Polynomial Regression (EPR).…”

“…Applications of SVM both for regression and classification are numerous in different sectors. In hydraulics and hydrology, examples include pipe failure detection in water distribution networks [36], prediction of urban water demand [37] rainfall-runoff modelling [38], flood forecasting [39], as well as reliability analysis [40][41][42] and dam safety [4,5,8,9,43,44].…”
