In recent years, Group Decision Making has been studied and applied in many fields. In a complex system, there is a lot of components that change time by time, dynamic, multi-dimension, etc. There are a lot of challenges for researching about this system. The system can't be centralized controlled. So, the distributed approach is the core of the studying. Inspired by reality, we propose an approach for forming the group through local interaction in the multi-agent system. The research mention

... ree main elements that are, criteria to identify a group; choose the representative; the representative make a decision. The paper only describes the stage for forming the group based on the position of the agents in two-dimensional space. This study is the first stage of making the multi-level multi-agent system that we are studying. The model is applicated for describing behaviors of passengers in the departure lounges at the airports when an evacuation situation occurs.
