Abstract
This paper aims to improve the argument based negotiation framework R-2-IBN to overcome the cooperation problem within the extended enterprise by the agent-oriented model named MAIS-E-2. In order to overcome the problem of cooperation in general and conflict resolution which prevent this practice in particular, we propose as a solution the integration of game theory foundations into two modules of R-2-IBN framework which are: "Argument Evaluation" module and "Argument selection" module. Finally, we expose the evaluation and the validation of our work through the use of a port application.
