Logarithmic least squares prioritization and completion methods for interval fuzzy preference relations based on geometric transitivity
A geometric consistency definition is proposed for interval fuzzy preference relations (IFPRs). The existing consistency definitions for IFPRs are flawed by not being robust to permutations of the pairwise judgments. A logarithmic least squares model is developed to derive interval weights from any IFPR. A logarithmic-least-squares-based approach is put forward to estimate missing values of incomplete IFPRs.
