This paper presents a decision support system that can be accessed from anywhere and anytime, thanks to the use of mobile phone technology. We assume that the number of alternatives and experts are not fixed, and therefore, they can be added or deleted over time. Experts use multi-granular linguistic information (different sets of labels) and can choose among different preference representation formats to express their preferences: fuzzy preference relations, orderings and utility functions. In such a framework, adequate consensus processes are designed to achieve an agreement before making a final decision.

Keywords: Decision support systems (DSS), group decision making (GDM), mobile internet (M-Internet), multi-granular linguistic information.
