Solving multiple criteria choice problems by interactive trichotomy segmentation

Questions guiding the choice of a multicriteria decision aiding method

“…This type of results is particularly well adapted to the contexts where the set A is not defined a priori, like Clinical decision support in emergency room (9) and Credit granting (10). It can also be convenient to presort when a large number of potential actions have been listed at the starting point of the decision process (Jaszkiewicz and Ferhat 1999). This could happen in such contexts as: Commuter rail line (1), or Siting of a nuclear power-plant (2).…”

Verbal ordinal classification with multicriteria decision aiding

“…Traditional methods of classification that work with numerical information (Berkson, 1944;Bliss, 1934;Fisher, 1936;Jaszkiewicz and Ferhat, 1999;Mousseau et al, 1998Mousseau et al, , 2003Smith, 1947) are not suitable for considering verbal estimations of objects. In traditional methods, the decision maker (DM) is forced to express his or her preferences in a quantitative form.…”

“…Classification is necessary in a variety of problem areas such as medicine, financial management and economics as well as marketing research, human resources management, production system management and technical diagnostics, pattern recognition, environment ecology and energy management (Arondel and Girardin, 1998;Berkson, 1944;Brans and Mareschal, 1994;Dias and Tsoukias, 2004;Jaszkiewicz and Ferhat, 1999;Keeney and Raiffa, 1976). For example, a doctor performs a diagnosis of a patient based on the analysis of his or her symptoms; a financier estimates credit risk before investments; an analyst of production system controls and monitors complex functioning systems.…”

“…Other methods can be found in operational research (e.g. rough set theory (Greco et al, 1998), fuzzy logic (Nozaki et al, 1996), multiple criteria analysis (Jaszkiewicz and Ferhat, 1999;Larichev, 1995;Larichev andMoshkovich, 1994, 1997;Larichev et al, 1990Larichev et al, , 2002aRoy, 1981). The selection of a method to be used depends greatly on the availability of initial information, the type of such information, completeness of this information, the level of uncertainty, and the requirements to the final decision.…”

“…There are several methods of multiple criteria analysis for ordinal classification, among these Trichotomic Segmentation (Jaszkiewicz and Ferhat, 1999;Roy, 1981), and Electre Tri (Mousseau et al, 1998), which work with numerical estimations of objects. However, such transformations made by DM evoke information losses.…”
