Abstract

In the analytic hierarchy process (AHP), interval judgments instead of precise ratios are widely accepted and can be practically used to solve decision-making problems when uncertainty exists because of scant information available or insufficient understanding of the problem. This paper presents a simple and effective method for finding the extreme points in a range of interval ratios (such as loose articulation, minimum number of interval ratios, and general interval ratios) and ultimately for establishing the dominance relations among alternatives using the identified extreme points. This is followed by an enumeration or simulation approach to manage situations in which the best or a full ranking of alternatives remains unidentified.

5. Concluding remarks

In this paper, we presented an AHP-based decision-making method for uncertain judgments that include a range of interval ratios: loose articulation, minimum number of interval ratios, and general interval ratios. Our approach is distinct from previous studies in several ways. First, we deal with interval ratios in a unified framework in which the extreme points of the loose articulation can be obtained by a formula or dual programming approach, and those for a minimum number of interval ratios and the general interval ratios can be obtained by a simple procedure.
