Pipe replacement in a water supply network: coordinated versus uncoordinated replacement and budget effects. van Dijk, D. & Hendrix, E. M. T. Informatica, 27(2):387–403, 2016. doi abstract bibtex Operators of underground water supply networks are challenged with pipe replacementdecisions, because pipes are subject to increased failure rates as they age and financial resourcesare often limited.We study the optimal replacement time and optimal number of pipe replacementssuch that the expected failure cost and replacement cost are minimized, while satisfying a budgetconstraint and incorporating uncoordinated and coordinated replacement. Results show that coordinatedreplacement is economically preferred to uncoordinated replacement. It depends on the sizeof the budget whether the increase in the number of pipe replacements is sufficient to reduce thetotal expected failure cost.
