Decision Supports Systems (DSS) are computer-based systems which are characterized as interactive systems, used to help decision makers to utilize data and models to solve problems and support activities linked to their decision making process by enhancing it (Ali, et.al, 2017). Until now most of DSS are developed and implemented for business sector depending on the company/organization perspectives, still there are few done within the area of sport. With those premises, the objective of this paper is to assess the current state of art implementation of new technologies – in the specific the Video Assistant Referees (VAR) – and the impact that it has in supporting the referees in their decision making process during soccer matches. In this paper, we propose a review of literature, starting with the online database through specific keywords in order to assume the current state of analysis.
