- Defining a model for agent-based participant support in group decision meetingPublication . Marreiros, Goreti; Ramos, Carlos; Neves, José; Ramos, Carlos; Vale, ZitaThis paper aim to present a multi-agent model for a simulation system, whose goal is to help one specific participant of multi-criteria group decision making process. This model has five main intervenients types: the human participant, who is using the simulation and argumentation support system; the participant agents, one associated to the human participant and the others simulating the others members of the decision meeting group; the directory agent; the proposal agents, representing the different alternatives for a decision (the alternatives are evaluated based on criteria); and the voting agent responsible for all the voting mechanisms. At this stage it is proposed a two phase algorithm. In the first phase each participant agent makes his own evaluation of the proposals under discussion, and the voting agent proposes a simulation of a voting. In second phase, after the dissemination of the voting results, each one of the participant agents will argue to convince the others to choose one of the possible alternatives. The arguments used to convince a specific participant are dependent on agent knowledge about that participant. The two-phase algorithm is applied iteratively.
- Webmeeting – A group decision support system for multicriteria decision problemsPublication . Sousa, Jorge Pinho de; Marreiros, Goreti; Ramos, Carlos; Ramos, Carlos; Vale, ZitaWebMeeting is a Group Decision Support System designed to support distributed and asynchronous meetings. It aims at helping geographically distributed people and organisations in solving multi-criteria decision problems, by allowing their participation in the decision process through the Internet. This paper presents the WebMeeting architecture, as well as its main functionalities, namely the selection of alternatives, argumentation, voting techniques and meeting setup.
