Evaluating the Perception of the Decision Quality in Web-Based Group Decision Support Systems: A Theory of Satisfaction

Abstract

The future and success of organizations depend greatly on the quality of every decision made. It is known that most of the decisions in organizations are made in group. With the purpose to support the decision-makers anytime and anywhere, Web-based Group Decision Support Systems have been studied. The amount of Web-based Group Decision Support Systems incorporating automatic negotiation mechanisms such as argumentation is increasing nowadays. Usually, these systems/models are evaluated through mathematical proofs, number of rounds or seconds to propose (reach) a solution. However, those techniques do not say much in terms of decision quality. Here, we propose a model to predict the decision-makers’ satisfaction (perception of the decision quality), specially designed to deal with multi-criteria problems. Our model considers aspects such as: alternatives comparison, style of behaviour, emotions, mood and expectations. The proposed formulation matches the assumptions previously defined in the literature.
