Since 1989 when the EWG-DSS was founded, the society has organized annual events including workshops, mini-conferences and conference-streams. These events have received wide participation from researchers, academics, practitioners, developers and other professionals within the EWG-DSS network and colleagues from other international DSS communities and professional societies. Along with the fast increase of our membership and scale of our events, not only in terms of numbers but also the internationalization, in 2015 the EWG-DSS decided to re-brand its major annual event as international conference. The ICDSST conferences have the unique title of International Conference on Decision Support System Technology, but with a different theme each year following the trend and state-of-the-art in the DSS field. The name of the conference has a corporate identity with the name of the IJDSST journal, which is the official journal publication of the Euro Working Group on Decision Support System, having published several special issues from research conducted by the EWG-DSS.

The ICDSST 2020 aims at the development of  Decision Support Systems and Technologies (tools and knowledge) that capture the relevance and support the human factor and the cognitive orientation in decision making.
