Evaluation and Decision Models: A Critical Perspective
TL;DR: This chapter discusses the process of building and aggregating evaluations for decision-making on the basis of several opinions and the challenges of dealing with uncertainty.
Journal ArticleDOI
Incomplete Information Tables and Rough Classification
TL;DR: This paper introduces two generalisations of the rough sets theory that introduce the use of a non symmetric similarity relation in order to formalise the idea of absent value semantics and shows that for the valued tolerance approach it is possible to obtain more informative approximations and decision rules.
Book
Evaluation and Decision Models with Multiple Criteria: Stepping Stones for the Analyst
TL;DR: This work presents a meta-modelling architecture suitable for multi-Dimensional preference models and shows clear trends in preference-based decision-making that have been identified in recent years.
Book ChapterDOI
On the Extension of Rough Sets under Incomplete Information
TL;DR: Two generalizations of rough set theory are introduced, based on non symmetric similarity relations, while the second one uses valued tolerance relation, which provides more informative results than the previously known approach employing simple tolerance relation.
Journal ArticleDOI
From decision theory to decision aiding methodology
TL;DR: The author’s partial and personal historical reconstruction of how decision theory is evolving to a decision aiding methodology is presented, showing mainly how “alternative” approaches to classic decision theory evolved.
