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)

\( \left(\frac{\mathbf{1}}{\mathbf{9}}.\frac{\mathbf{1}}{\mathbf{9}}.\frac{\mathbf{1}}{\mathbf{8}};\frac{\mathbf{1}}{\mathbf{9}}.\frac{\mathbf{1}}{\mathbf{9}}.\frac{\mathbf{1}}{\mathbf{7}}\ \right) \)
