Formation in Electronic Marketplaces
We address long-term
coalitions that are formed of both customer and vendor agents after evaluating
their relationships with other agents in the system. We present a coalition
formation mechanism designed at agent level and analyzed at both system
and agent levels. Evaluation has been conducted to compare agent strategies
(individual vs. social) and to analyze the system behavior under different
circumstances. Our results show that the coalition formation mechanism
is beneficial for both the system (it reaches an equilibrium state) and
for the agents (their gains increase exponentially in time).
