Abstract: We generalized triangular fuzzy numbers from ℝ to ℝ2 . By defining parametric operations between two α-cuts, which are regions, we obtained parametric operations for two triangular fuzzy numbers defined on ℝ2 . We also generalized triangular fuzzy numbers from ℝ2 to ℝ3 . By defining parametric operations between two α-cuts, which are subsets of ℝ3 , we derived parametric operations for two triangular fuzzy numbers defined on ℝ3 . For the calculation of Zadeh’s principle operators, the definition of parametric operations between two α-cuts, which are subsets of ℝ3 , is critical.
