In automated negotiation, team negotiation is poised as one of the most important negotiation techniques. A team is a group where multiple interdependent agents participate in negotiations as a negotiating party during the course of negotiations. Existing team negotiation strategies did not consider the change in decisions due to the interdependencies within the team. In this paper, we propose a team negotiation strategy that considers the interdependencies within the same team. Towards this end, in the proposed negotiation strategy, we first set the parameters that represent the interdependencies that exist within the team in both directions. Thereafter, a voting process is performed in each direction. By weighting the degree of dependency of each team member, a change in agent decision due to its dependency relationships is measured. A comparative experiment with the existing team negotiation strategies showed the efficiency of the proposed strategy.
