Multi-attribute decision-making (MADM) can be used for determining the priorities among various available choices. In the present work, the priorities in the case of the rehabilitation material of the water distribution network (WDN) is identified using different MADM techniques. The ranking of technical solutions is performed using three different methods of MADM techniques which include the Analytical Hierarchy Process (AHP), Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE), and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) methodology. The ranking of the alternatives so obtained is compared with other studies performed using different MADM methods. It is observed that the best solution i.e., the alternative with rank one always remains the same in all the techniques, clearly highlighting the alternative which in the present case study is fiber cement pipe is the supreme choice for the rehabilitation of pipes in WDN of Cluj-Napoca, Romania. In the present study ductile cast iron, gray cast iron, polyethylene, prestressed concrete, fiber cement, and steel materials are compared for the rehabilitation of WDN. A similar study can be performed on a real-life network involving a larger number of choices. The MADM techniques can also be applied to identify the best solution from the various feasible solutions that are generated by the multi-objective optimization technique in the form of a Pareto front. This can ease the decision-making process for a design engineer.
