Criteria weight determination within Interval Rough CODAS approach for Water Resources management

Water Resources Management is a major problem nowadays, especially in Tunisia. Since criteria weights play a very significant role in the ranking Multicriteria Decision Making (MCDM) methods, the current work is applied to find criteria weight through Interval Rough CODAS method (IR-CODAS) which should rank the alternatives using two measures: the Euclidean and the Taxicab distance, to overcome the subjectivity of the group decision-makers. For that, we aim to develop a mathematical programming model eliciting objective weight parameters of the IR-CODAS method given consideration to the MCDM problems with lack of criteria's relative importance coefficients (weights) under interval rough sets. Thereupon, the applicability of the proposed model is illustrated in a case study to evaluate and select the best water resources management projects in Sfax (Tunisia).
