Abstract

This paper presents a method for modeling the inconsistency of the decision maker's judgments by transforming comparison matrices into sets of local priorities. Such sets, called extended regions, are processed in the hierarchy through linear programming into dominance results which become more complete as the decision maker enters new comparisons and tightens earlier judgments. In this way, the analysis of comparison matrices with possibly missing or interval entries provides intermediate results after each preference statement.
