Comparing results of four decision support software tools on mains replacement

“Water companies use software tools to support decisions on mains rehabilitation. Four tools for decision support were quantitatively compared in this research. This comparison was done by making four assessments of one water distribution network, with the same strategic boundary conditions. The four tools were able to provide a volume of candidates for replacement that fit more or less to the given condition for a desired volume of replacements. Comparing the
individual mains proposed by these tools shows however large differences between the tools. These differences are mainly based on differences in modelling approach and the way these tools have been implemented at water companies.”
