We study the problem of fuzzy preference relations in group decision making. Group decision problems need all experts express their preferences using the same preference representation format. However, in real practice, this is not always possible because each expert has their unique characteristics which regard to knowledge, skills, experience, and personality, which implies that different experts may express may express their evaluation by means of different preference representation formats. Therefore, we use the order weighted averaging (OWA) operator and order weighted geometric (OWG) operator in the aggregation of group decision making problems. The main contribution of this paper is the easy and extensible solution to group decision problems. Therefore, we studied literatures about O WA OWG and fuzzy preference relation. We results are created the proposed of solving a multi-criteria decision making problem using OWA and OWD operator. Finally, we give an empirical example where we can see the different results obtained by using the OWA and OWG operator in fuzzy preference relations in group decision making.
