Consequently, consumers in such an environment require efficient mechanisms to match their demands (requested services) to supplies (available services). Businesses, on the other hand, aim to achieve efficient allocation of their resources. This chapter introduces a combination of Artificial Intelligence mechanisms and Computational Economics concepts as a means of solving the above mentioned problems. These mechanisms and concepts are implemented in agent-based electronic markets. Electronic markets function as digital intermediaries that create value by bringing consumers and providers together to create transactional immediacy and supply liquidity, by supporting the exchange of demand and supply information, and reducing transaction costs. The efficiency of the created multi-agent system is realized by applying novel discovery and/or negotiation models.

In order to enable ubiquitous personalized services, communication systems should allow users to specify their context, or their mobile devices and network infrastructures should automatically sense their context and offer enhanced service provisioning solutions. In this paper, we propose an agent-based solution that supports context-aware provisioning of IP multimedia subsystem (IMS)-enabled ubiquitous services. Using agent technology, multimedia communication, controlled by SIP and enriched with context-related events delivered by SIP’s event mechanism, can be seamlessly provisioned, taking into account not only mobility issues and context-awareness, but also the semantics of exchanged events. This paper proposes a multi-agent system that will enable users to consume context-aware ubiquitous services in a seamless (i.e., automated) way, providing optimal provisioning of SIP-based multimedia services according to user preferences.

Online publishers use different formats of unit price auctions to sell advertising slots. In the Trading Agent Competition Ad Auctions (TAC/AA) game, intelligent software agents represent a publisher which conduct keyword auctions and advertisers which participate in those auctions. The publisher is designed by game creators while advertisers are designed by game entrants. Advertisers bid for the placement of their ads on the publisher’s web page and the main challenge placed before them is how to determine the right amount they should bid for a certain keyword. In this paper, we present the CrocodileAgent, our entry in the 2010 TAC AA Tournament. The agent’s architecture is presented and a series of controlled experiments are discussed.

Traditional methods for studying market mechanisms, utilized by economists and mathematicians, use analytical approaches. Today, the rapid proliferation of the Internet is stimulating the transformation of classical markets into electronic markets (e-markets). Traditional theories cannot adequately cover the dynamics of complex computing systems, such as the e-market,

This paper offers an agent-based solution as a potentially adequate approach for the automation of supply chain management. The greatest obstacle in SCM research is obtaining benchmark designed solutions since it is difficult to simulate real business environments,

This is especially emphasized in lives of users that belong to Generation Y. Young people often communicate and share various personal information with their family, friends or colleagues through virtual communities that are based on social relations. By introducing social networking concept into the mobile network domain, proliferation

The Power Trading Agent Competition (Power TAC) is a simulation platform for evaluating trading strategies for the smart grid electricity markets: the tariff and the wholesale market. This paper gives an outline of our proposed strategies for reaching agreements on the Power TAC wholesale market.
