An Agent - Based Architecture with Centralized Management for a Distance Learning System

In this paper we have proposed a multi-agent architecture for an Intelligent Tutoring System using TROPOS methodology. Basic assumptions of constructivist learning have been taken into account in analysis and design activities. Nine types of agents are distinguished in the presented system. We have centralized management in the proposed architecture which is done by an agent called Manager Agent. This strategy of centralized management will result in a more coherent and effective Tutoring System than other systems not using such an agent, since it applies control flow of agents and decreases agents' useless communications which may cause destructive congestion in system. This text discusses the methodological and theoretical aspects of the proposed architecture for an agent-based Intelligent Tutoring System regarding the TROPOS methodology phases.
