Fixed charge transportation problem with type-2 fuzzy variables
Formulation of two fixed charge transportation problems with type-2 fuzzy parameters. Transportation Costs, supplies, demands, conveyance capacities are taken as type-2 fuzzy variables. CV-based reduction methods and centroid method are applied for defuzzification. Chance-constrained programming model is formulated using generalized credibility measure for the second problem. Sensitivity analysis is done for different generalized credibility levels.
