This chapter presents a methodology for dealing with a multicriteria ranking problem using a preference model in the form of a set of decision rules induced from decision examples. In the first section, the authors present the setting of the considered multicriteria ranking problem. In the second section, they introduce the concept of the pairwise comparison table (PCT). The third section concerns rough approximation of two comprehensive preference relations specified by a decision maker (DM): outranking relation S and nonoutranking relation Sc. The fourth section discusses induction of decision rules from rough approximations of S and Sc, and application of these rules on a set of objects to be ranked. The fifth section concerns exploitation of the preference structure resulting from application of decision rules. The chapter finally presents an illustrative example that demonstrates usefulness of the proposed approach. © 2013 John Wiley & Sons, Ltd.
