Ranking Inter-basin Water Resources Projects Using Fuzzy Multiple Attribute Group Decision Making Method

Abstract

Dealing with Water Scarcity is one of the important probleme in water resources management. There is no one of financial capability to execute all the water resources projects in one lot, so it is important to rank execution projects. In this study, one of the fuzzy multiple attribute decision making methods was employed for ranking some of the inter-basin water transfer projects, by using different critaria and modifying the Raj and Kumar method for both benefit and cost critaria conditions. The approach has been applied to the Karun river basin. For ranking alternatives, first critaria and their weight were determined and then 10 inter-basin water resources projects of Karun river with 8 critaria were considered. The weight of each criterion determined by 5 water resources experts. The fuzzy weights of alternatives are computed by using standard fuzzy arithmatic. The concept of maximizing snd minimizing sets are used to computed the total utility of each of alternatives. Finally, the results of maximizing and minimizing method were compared to FDM software.
