I.J. Pérez, F.J. Cabrerizo, E. Herrera-Viedma. A Mobile Decision Support System for Dynamic Group Decision Making Problems. IEEE Transactions on Systems, Man and Cybernetics - Part A: Systems and Humans doi:10.1109/TSMCA.2010.2046732, in press (2010).
The aim of this paper is to present a decision support system model with two important characteristic: (i) mobile technologies are applied in the decision process, and (ii) the set of alternatives is not fixed over time to address dynamic decision situations in which the set of solution alternatives could change throughout the decision making process.We implement a prototype of such mobile decision support system in which experts use mobile phones to provide their preferences anywhere and anytime. In order to get a general system, experts preferences are assumed to be represented by different preference representations: fuzzy preference relations, orderings, utility functions, and multiplicative preference relations. Because this prototype incorporates both selection and consensus processes, it allows to model group decision making situations. The prototype incorporates a tool to manage the changes on the set of feasible alternatives that could happen throughout the decision process. In such a way, the prototype provides a new approach to deal with dynamic group decision making situations to help making decisions anywhere and anytime.
