Information Concepts and AHP 

Abstract

In this paper we present preliminary research on how information (or entropy) based measures can be used by a decision maker (DM) using the Analytic Hierarchy Process (AHP) to assess judgment accuracy, and to decide when to stop the process of pairwise comparisons. We introduce some information indices, and illustrate their use in the Analytic Hierarchy Process by means of some examples. Furthermore, we research the issue of how to measure the information content of redundant judgments, and investigate the relationship between information and degree of redundancy through the use of simulated judgments.
