The Stability of AHP Rankings in the Presence of Stochastic Paired Comparisons
This paper develops a methodology for analyzing the stability of AHP rankings for decision problems in which the paired comparison judgments are stochastic. Multivariate statistical techniques are used to obtain both point estimates and confidence intervals of rank reversal probabilities. We show how simulation experiments can be used to assess the stability of the preference rankings under uncertainty. High likelihoods of rank reversal imply that the AHP rankings are unstable, and that additional analysis of the decision problem may be in order.
