Researchers, academics, practitioners, students, and all professionals around the world interested or involved in group decision making and decision support are welcome to submit their work to the conference. In addition, all EWG-DSS members and collaborators from other EURO WGs and DSS Communities, and all GDN members and collaborators from other INFORMS sections, who have consistently contributed to the research in the Group Decision and Negotiation and Decision Support Technology, are highly encouraged to submit their papers and participate in the conference.

Suggested topics include, but are not limited to, decision theory, systems theory, participatory and collaborative methodologies, technological tools (from design to implementation), societal and behavioural perspectives, and applications and case studies.

The topics are organized in two major groups, according to the interests of the two groups, as listed below. For GDN, there are conference streams available.
