This paper extends standard agency theoretic models to explicitly take into account the presence of multiple criteria at the agent level. Two possible approaches for this extension are discussed. In the first approach, we consider only the minimum information that the principal might posses...

One problem impeding the use of linear decision models in practical applications is the difficulty in precisely specifying weights. In this paper, we analyze an approach to establish the stability of a decision, given approximate information on weights. This approach is based on comparing the...

Decision theoretic models of group decision processes usually assume a given set of alternatives, about which the decision has to take place. In realistic group decision situations, however, alternatives are often not specified a priori, but are created during the group process from different...

This paper discusses the problem of estimating aspiration or reference levels in criteria space from choices between alternatives characterized by multiple criteria. Several methods for such estimations are developed and compared, taking into account both solution quality and computational...

The paper introduces a new method for the graphical representation of multicriteria decision problems with discrete sets of alternatives. The approach proposed here extends projection techniques based on principal component analysis by incorporating information about preferences between...
