Set choice problems with incomplete information about the preferences of the decision maker

Abstract

We consider the problem of selecting a predetermined number of objects from a given finite set. It is assumed that the preferences of the decision maker on this set are only partially known. Our solution approach is based on the notions of optimal and non-dominated subsets. The properties of such subsets and the objects they contain are investigated. The implementation of the developed approach is discussed and illustrated by various examples. © 2010 Elsevier B.V. All rights reserved.
