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.
