Multicriterion decision making in river basin planning and developement

Five Multicriterion Decision Making (MCDM) methods, namely, ELECTRE-2, PROMETHEE-2, Analytic Hierarchy Process (AHP), Compromise Programming (CP) and EXPROM-2, are employed to select the best reservoir configuration for the case study of Chaliyar river basin, Kerala, India. Spearman rank correlation coefficient is used to assess the correlation between the ranks obtained by the above MCDM methods. Although these methods follow different approaches, the analysis has shown that the same preference strategy is reached by all the methods. Comparative evaluation of MCDM methods revealed that Compromise Programming is best suited for the present case study.
