A rationality-based modeling for coalition support

We present a game theoretic model for multi-agent resource distribution and allocation where agents in the environment must help each other to survive. Each agent maintains a set of two-tuples T=(A, P) called friendship values representing actual friendship and perceived friendship. The model directly addresses problems in reputation management schemes in multi-agent systems and peer-to-peer distributed systems. We present algorithms for maintaining the friendship values as well as a utility equation used in each agent´s decision making. For an application problem, we adapted our formal model to the military coalition support problem in peace-keeping missions. Simulation results show that efficient resource allocation and sharing with minimum communication cost is achieved without centralized control.
