In the combat simulation of human behavior representation (HBR) preciseness, it is all-important to build the conflict resolution model that can really reflect battlefield behaviors. According to shortages of existing research and analysis of conflict behaviors, this research presents an argumentation-based collaborative CGF hierarchy negotiation model, defines some related concepts, based on which the negotiation process in conflictions was studied and the Utility Theory-based arguments strength qualified evaluation algorithms was implemented, which is used for the selection of optimal proposal and confirmation of common belief. As is testified in fact, it can reflect the real battlefield behaviors under conflicts and ensure the consistency of negotiation during the collaboration process.
