Decentralized Strategy for Supporting Multi-agent Negotiation of Several Aspects of Different Products

In virtual markets based on multi-agent systems, clients and providers delegate the responsibility of buying or selling a product or service to software agents. In this sense, decentralized negotiation strategies in multi-agent systems are the key to allow that agents to reach agreements. However, in environments where there is not any mediator, to reach consensus is not warranted. In this work, we propose a decentralized strategy of negotiation in order to two or more agents may negotiate as a group at the same time several characteristics of several products. We apply this proposal in a virtual market simulating ChileCompra, where provider agents generate coalitions to satisfy tenders requesting several products or services.
