Abstract: |
A negotiation chain is formed when multiple related nego-
tiations are spread over multiple agents. In order to appro-
priately order and structure the negotiations occurring in
the chain so as to optimize the expected utility, we present
an extension to a single-agent concurrent negotiation frame-
work. This work is aimed at semi-cooperative multi-agent
systems, where agents do not cheat or intend to hurt other
agents even as they focus on their own goals. We intro-
duce a pre-negotiation phase that allows agents to transfer
meta-level information. Using this information, the agent
can build a more accurate model of the negotiation in terms
of modeling the relationship of flexibility and success proba-bility. This more accurate model helps the agent in choosing a good negotiation solution. The agent can also use this information to allocate appropriate time for each negotiation, hence to find a good ordering of all related negotiations. The experimental data shows that these mechanisms improve the agents??? and the system???s overall performance significantly.
