  The social network analysis (SNA), branch of complex systems can be used in
the construction of multiagent systems. This paper proposes a study of how
social network analysis can assist in modeling multiagent systems, while
addressing similarities and differences between the two theories. We built a
prototype of multi-agent systems for resolution of tasks through the formation
of teams of agents that are formed on the basis of the social network
established between agents. Agents make use of performance indicators to assess
when should change their social network to maximize the participation in teams
