Intelligent Rational Agent Model Research Articles

ADAM

In today’s world, databases and database systems have become an essential component of everyday life, so much so that a life without DBMSs has become inconceivable. This article focuses on relational database management systems in particular, and proposes a novel and innovative multi-agent system that would autonomously and rationally administer and maintain databases. The proposed multi-agent system tool, ADAM, is in the form of a self-administering wrapper around database systems, and it addresses and offers a solution to the problem of overburdened and expensive DBAs with the objective of making databases a cost-effective option for small/medium-sized organizations. An implementation of the agent-based system to proactively or reactively identify and resolve a small subset of DBA tasks is discussed, and the GAIA methodology is used to outline the detailed analysis and design of the same. Role models describing the responsibilities, permissions, activities, and protocols of the candidate agents, and interaction models representing the links between the roles, are explained. The Coordinated Intelligent Rational agent model is used to describe the agent architecture, and a brief description of the functionalities, responsibilities, and components of each agent in the ADAM multi-agent system is presented. Finally, a prototype system implementation using JADE 2.5 and Oracle 8.1.7 is presented as evidence of the feasibility of the proposed agent-based solution for the autonomous administration and maintenance of relational databases.

Service-oriented e-Marketplace: an agent-based model

This paper develops a cooperative distributed systems framework for e-Marketplaces. We propose a business-centric knowledge-oriented architecture (BCKOA) framework. In this framework, we envision the e-Marketplace as a collection of economically motivated software agents that support the trading processes of several e-Business models. It enables and supports common integration and economic services between market participants, such as brokering, pricing and negotiation. The proposed architecture accommodates mechanisms of various market structures. This paper, however, will focus on commodity and Vickrey auction markets. It will briefly discuss the implementation of a prototype for BCKOA-based e-Marketplace using a coordinated, intelligent rational agent model and the Foundation of Intelligent Physical Agent specifications.

EMarketplaces for enterprise and cross enterprise integration

Businesses today must collaborate more frequently with partners to build virtual organizations and supply-chains that reduce times-to-market and costs. This paper argues that an electronic marketplace ( eMarketplace) is a promising model for eBusiness applications. The architecture for this integrated environment is business-centric and knowledge-oriented. In this architecture, the eMarketplace exists as a collection of economically motivated software agents of cooperative distributed systems. It enables and supports common integration and economic services between market participants. This paper focuses on developing an agent-oriented dynamic trading mechanism (Vickrey auction) and supply-chain integration for the eMarketplace. A prototype is developed for a Vickrey eMarketplace using a coordinated, intelligent rational Agent model and a FIPA-compliant platform.
