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...

We propose a new method for evaluating the benefits of decision-oriented information systems. This method is based on a detailed analysis of decision processes. Using prescriptive decision theory, correct results are established for different sub-phases of the process and possible deviations...

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...

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...

Hierarchische Kennzahlensysteme stellen eine bedeutende konzeptuelle Grundlage für Management- Informationssysteme dar. In dieser Arbeit wird ein bisher unberücksichtigter Aspekt der Abweichungsanalyse in derartigen Kennzahlensystemen aufgegriffen: die Konsistenz der als signifikant...

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...
