When it comes to a multiple criteria and multiple actors decision-making problem known as a group decision support problem, the literature
generally mentions two ways to aggregate the preferences of decision-makers to achieve consensual outcomes. The first class of group
decision support methods run a same multi-criteria method for each decision-maker and thereafter, based on the individual result obtained,
find a consensual result. The second class of methods first find a consensus on the preferences of decision-makers and then apply a
multi-criteria method based on these consensual preferences to finally have a consensual result. In this work we propose a new method,
belonging to the second class of methods for solving group decision problem. This method, called Median Weighted Product Method
for Group Decision Support (MWPM-GDS) aims to achieve quickly and easily results that reflect as accurately as possible the choice of
each decision-maker when solving group decision support problems. We applied the proposed method to two well-known examples in the
literature and compared the results with those of two other group decision support methods to show its effectiveness
