Research On Multi-agent-based Distributed Applications

Agent and Multi-Agent system are one of the most active research aspects in the field of computer science and technology, information engineering and network and commutation. The original meaning of Agent is "deputy" ; witch means one person deputes the other person to something else or points to the way and measure of accomplishing something. The distinct characteristics of agent are adaptively, sociality reactivity, temporal continuity, autonomy and mobility. The theory and technology of Multi-Agent system are most about how the single agents isolated in logic or physical position correspond and collaborate each other to solve problem and accomplish missions.This paper introduces the relatively knowledge of Multi-Agent system, such as the background of the appearance of Multi-Agent system, the commutation language and system of agents, the correspondence model of Multi-Agent system and the collaboration model of Multi-Agent system. And introduces a Multi-Agent system on the base of WWW, the structure of the system and the design of each components are also mentioned in this paper. Based on this Multi-Agent system, the author brings in an example-network assistant teaching system. In this part, the component and the structure of the system are presentation, especially the core of the system-tutor agent' s function and it' s realization.At the end of this paper, the author contrasts the agent with object, and look forward to the prospective usage of Multi-Agent system.
