A fuzzy group decision making approach to select the best alternative for sustainable sediment management in the Dez dam reservoir
Pages 153-167
The purpose of this research is to develop a new fuzzy group decision making algorithm and apply it to select the most preferred alternative for sediment management in the Dez dam reservoir. In this way, nine potential alternatives for sediment management in the Dez reservoir and four criteria (technical and executive requirements, economic factors, social welfare, environmental impacts) are selected. In order to evaluate different alternatives, firstly, the collective group weight of each alternative is calculated considering assessment of a group consisting of four criteria. And after that, the best alternative is selected using the proposed fuzzy group decision making methodology. The results of this study showed the efficiency of the application of fuzzy group decision making in sediment management. Application of the proposed method helps to balance the whole criteria and to select the best alternative.
