Selectivity the Khersan 1 Dam and Power plant by Using WASPAS and its Comparison with Other Multiple Attribute Decision Making

Selectivity the dams and Power plants is one of the most important issues in water resources management. The purpose of this paper was Selectivity the Khersan 1 dam and powerhouse by using one of the newest of the Multiple Attribute Decision Making (MADM) method in the name of Weighted Aggregated Sum Product Assessment (WASPAS) and its comparison with other MADM methods. In this case study that data required for making decision matrix is obtained in previous research, three alternatives: D axis- concrete arch, D axis- Pebble and F axis- concrete arch for selectivity by using WASPAS method with the help of the Excel 2010 software was analyzed. Calculated scores showed that D axis- concrete arch has achieved first priority (Q=0.9081), F axis- concrete arch has achieved second priority (Q=0.8487), finally D axis- Pebble has achieved third priority (Q=0.8202). Generally it can be said that SAW, AHP and WASPAS methods have led to the same result while TOPSIS had different result.
