Due to the uncertainty of battlefield environment, the coherence of organizational behavior is often blocked by the conflicting beliefs among team members. Yet there are few conflicts resolving mechanisms embedded in existing models of CGF. Aiming at human behavior representing (HBR) preciseness requested by combat simulation, a negotiation based conflicts resolving method is presented. Distinct from most existing theories, the negotiation behavior among CGF entities is cooperative. In addition, the communication and decision making behaviors of CGF entities are often restrained by the organization frame. Thus, the organization restrained negotiation behavior is preliminarily analyzed. Finally, a simple example is given. The results show that the method is available and efficient.
