基于多agent的分布式智能教学平台关键技术分析.docx

摘要
从人工智能领域中发展起来的多Agent系统,主要用于解决分布式问题。基于异地分布式学****的远程教育涉及多个身份之间相互协调的技术问题,其内在要求适合用Agent思想分析解决。
本论文中,对多Agent系统的研究进展、远程智能教学系统的发展现状及存在的问题进行了全面的评述,并从宏观到微观,对远程智能教学系统模型及其实现进行了深入研究。主要研究成果包括:
针对远程教育这一复杂大系统中广泛存在的异质智能子系统,探讨了该类分布式智能系统在协作中所面临的问题,提出了多Agent系统分布式问题求解模型。
提出了基于CORBA与多Agent的远程教学通信平台体系构架,实现了 KQML·IDL功能对接;在此基础上,给出基于移动Agent的系统监控模型CAMM, 以完成对系统中各Agent生命周期的监控。
对Agent的知识模型结构和表示方法进行了深入研究,综合教育心理学和认知科学理论,提出了FPBDI Agent心智模型;基于该模型,给出基于知识推理的教师Agent 以及基于知识学****的学生Agent的体系结构,实现了自适应动态教学策略调整;基于遗传算法以及模糊数学的思想方法,对能体现教学系统中考试予任务智能性的各
Agent加以实现。最后,提出基于扩展UML的多Agent系统建模思想,描述了采用Java语言实现
智能教学平台(ITPMAc)的主要工作,对前面提出的思想进行了验证。

Abstract
system developed from the domain of artificial intelligence is chiefly used to solve the distributing type long distance education based on distributing system involves technology problem of harmony mutually among many social statuses,and its inherent requirement could be met or analyzed with Agent’s idea.
In this progress and situation about Multi—Agent system,and the problem of
intelligent teaching system have been major research might be
summarized as the following:
f11 In this也esis,the problems of the intelligent system have been discussed in the cooperation;the solving model on distributing Multi-Agent system has been put forward in accordance with the intelligent subsystem that extensively exists in plicated system of
both macroscopic and microcosmic perspectives,the model
and implement to the intelligent teaching system have been developed in the research..
(2)In this thesis,Based on CORBA and Multi—Agent,munication platforrn flame of the teaching has been brought forward,and KQML-IDL’s function
docks have been realized as ,in order to plish the 1ife supervision,
CAMM(Monitor Model Based on CORBA and Mobile es forth.
