Abstract

Due to the costs to create conditions that allow participants to meet in the same place at the same

time (time, travel, etc.) the ubiquitous Group Decision Support Systems appeared allowing decisionmakers

to contribute with their ideas to the decision process anywhere and anytime. In this paper

is proposed a model which enables decision-makers to contribute with their ideas to the decision

process anywhere and anytime. It is a context-aware model which allows obtaining values of certain

typical variables of the affective context (emotions and mood) and to transform those values in advises.

So it enables the group reaches more easily the decision, strengthening the satisfaction of each

member with the decision made. Also here are presented the architecture and mechanisms which

could be used in the development of a prototype based on the presented model.
