A type-2 fuzzy interval programming approach for conjunctive use of surface water and groundwater under uncertainty

In this study, a type-2 fuzzy interval programming (T2FIP) method is developed for conjunctive use of surface water and groundwater under uncertainty. T2FIP can effectively tackle uncertainties expressed as a hybrid of type-2 fuzzy sets and interval numbers. In T2FIP, tradeoff between system benefit and system reliability can be analyzed to obtain the practical modeling outputs. Solution method based on interactive algorithm and type reduction …
