Economics Prioritization of the Allocation of Chahnimeh Reservoir Water Using Fuzzy Multiple-Criteria Decision-Making (FMCDM) Models

The main objective of the present study was to prioritize the allocation of water resources of Chahnimeh reservoirs from economic, social, and environmental perspectives in 2015-2016 season using fuzzy analytic hierarchy process (FAHP) and fuzzy technique for order preference by similarity of an ideal solution (FTOPSIS) as the branches of fuzzy multiple-criteria decision-making (MCDM) models. Data were collected from the experts and officials of the relevant organizations by a questionnaire. Nine parameters were used for prioritization and modeling. Results revealed that in FAHP from economic and social perspectives, the agriculture sector had the highest weights of 0.4 and 0.269, respectively. However, the priority to enjoy the water of three Hāmūn lagoons was granted to the environmental sector in environment perspective. FTOPSIS results confirmed the results of FAHP.
