  • Multiple criteria utility models for sorting incorporating veto related preference structures
    Bregar, Andrej, informatik
    In this research, veto related structures are introduced into multi-attribute utility models for classification and sorting in order to allow for the principles of constructivism, incomparability and ... non-compensation of unsatisfactory preferences. Several extensions are proposed to incorporate veto into additive and multiplicative models. The first approach builds on the concepts of UTADIS and ELECTRE TRI methods. The ascending procedure is applied to sort alternatives by comparing their global evaluations to utility thresholds that define the bounds of adjacent categories. The assignment and incomparability categories are obtained in this way. The second approach to aggregate utility and veto pertains to the case of hierarchical sorting. Properties of sorting models are also studied. Several characteristics are determined with a simulation study, and a special veto independency condition is considered. Because it deals with the decision-making problematics of sorting, the presented research complements our previous study which has assessed risk aversion of veto for the case of ranking.
