Abstract: The aim of this work is to develop a recommender in order system to help to choose a voting procedure. For this purpose, we have to implement these voting procedures in a GDSS (Group Decision Support Systems). Therefore, it involves to review the literature on voting procedures and voting tools in order to know their functionality. We will use a practical example to show the level of implementation of the platform in its current state. Finally, we will invoke the perspectives of future work to continue to improve the voting tools of GRUS (GRoUp Support).
