Importance level | Corresponding intuitionistic fuzzy sets | Reciprocal intuitionistic fuzzy sets |
---|---|---|
Equal Importance (EI) | (1, 1, 1; 1, 1, 1) | (1.1.1; 1.1.1 ) |
Weak Importance (WI) | (2, 3, 4; 1, 3, 5) | \( \left(\frac{\mathbf{1}}{\mathbf{4}}.\frac{\mathbf{1}}{\mathbf{3}}.\frac{\mathbf{1}}{\mathbf{2}};\frac{\mathbf{1}}{\mathbf{5}}.\frac{\mathbf{1}}{\mathbf{3}}.\mathbf{1}\ \right) \) |
Fairly Strong Importance (FSI) | (4, 5, 6; 3, 5, 7) | \( \left(\frac{\mathbf{1}}{\mathbf{6}}.\frac{\mathbf{1}}{\mathbf{5}}.\frac{\mathbf{1}}{\mathbf{4}};\frac{\mathbf{1}}{\mathbf{7}}.\frac{\mathbf{1}}{\mathbf{5}}.\frac{\mathbf{1}}{\mathbf{3}}\ \right) \) |
Very Strong Importance (VSI) | (6, 7, 8; 5, 7, 9) | \( \left(\frac{\mathbf{1}}{\mathbf{8}}.\frac{\mathbf{1}}{\mathbf{7}}.\frac{\mathbf{1}}{\mathbf{6}};\frac{\mathbf{1}}{\mathbf{9}}.\frac{\mathbf{1}}{\mathbf{7}}.\frac{\mathbf{1}}{\mathbf{5}}\ \right) \) |
Absolute Importance (AI) | (8, 9, 9; 7, 9, 9) | \( \left(\frac{\mathbf{1}}{\mathbf{9}}.\frac{\mathbf{1}}{\mathbf{9}}.\frac{\mathbf{1}}{\mathbf{8}};\frac{\mathbf{1}}{\mathbf{9}}.\frac{\mathbf{1}}{\mathbf{9}}.\frac{\mathbf{1}}{\mathbf{7}}\ \right) \) |
