Consistency prediction for incomplete AHP matrices

The efficiency of the Analytic Hierarchy Process can be improved if users can establish priorities without completing the entire set of pairwise comparisons. This study develops a methodology for predicting the consistency index and consistency ratio when pairwise comparisons are incomplete. Separate prediction equations are presented for each size of matrix from 5 to 10. These equations can be incorporated into AHP software so that users will have a predicted consistency ratio when making the decision to stop or proceed with more paired comparisons.
