In this study, we developed a multi-criteria-decision-making (MCDM) fuzzy AHP– VIKOR method with the aim to contribute to the improvement and development of MCDM methods. By combining and improving the existing AHP and VIKOR methods with the application of fuzzy logic theory, a novel fuzzy AHP–VIKOR method is for easier and clearer obtaining of optimal solutions. The new method was applied to obtain the findings in the analysis of four complex design solutions for canalisation, treat- ment, and pumping of atmospheric wastewater in the SPS in Makiš, an urban neighbourhood of Belgrade in Serbia. The analysis was carried out in relation to the stability of the solution by way of considering the use of different methods of MCDM optimisation, while taking into account ways of channelling, treatment, and evacuation of wastewater.
