Figure 2 Pareto Optical solution of MCDM In this study, MCDM was used for vulnerability ranking decision on dams, and assessment scores of each step of the hydrological safety evaluation results which was applied as payoff. It can be available for calculating dams' vulnerability ranking considered dams' hydrological safety. Compromise Programming(CP), PROME-THEE, VIKOR and TOPSIS, generally used as MCDM technique, were applied to determine the hydrological vulnerability ranking of dams According to each technique, the dam ranking was calculated. In conclusion, the most vulnerable dam and the most safety dam was selected. 3. ANALYSIS RESULTS In this study, It was ranked using various techniques of MCDM that hydrological safety assessment vulnerability ranking. Criteria of MCDM payoff matrix was shown in Table 3.
