An Argumentation-Based Approach to Multiple Criteria Decision

The paper presents a first tentative work that investigates the interest and the questions raised by the introduction of argumentation capabilities in multiple criteria decision-making. Emphasizing the positive and the negative aspects of possible choices, by means of arguments in favor or against them is valuable to the user of a decisionsupport system. In agreement with the symbolic character of arguments, the proposed approach remains qualitative in nature and uses a bipolar scale for the assessment of criteria. The paper formalises a multicriteria decision problem within a logical argumentation system. An illustrative example is provided. Various decision principles are considered, whose psychological validity is assessed by an experimental study.
