Water is a key index for development of a region. Due to limitation of financial resources and opportunities, ranking of projects is essential and multi criteria subjects. In this study the optimal ranking of nine projects of dam establishment in Chaharmahal and Bakhtiari province was carried out and the eleven qualitative and quantitative criteria were considered. For this purpose, two softwares, ELECTRE III and Expert choice, were applied. Since quantitative of qualitative results of the sensitivity analysis of the decision making methods has not been considered till now the use of changes Percentage parameter came to account.In this study the sensitivity analysis of the methods used to determine changes in decision making matrix and parameters for each method were quantified. The results showed that the most appropriate of the methods is ELECTRE III because it has less sensitivity to changes in ranking. Also the results showed that the model is very sensitive to eliminate the economic criteria(B/C: about 70.7%), meanwhile it is not sensitive to eliminate the dam height, employment and population concentration criteria.
