【摘要】 目前agent技术越来越成为人工智能研究的重点,并且人们一直以来在基于agent的定义和形式化模型上进行着探索,也已经出现了许多重大的理论成就,其中最著名的要数Rao和Georgeff的BDI模型,而目标作为BDI模型中一个重要概念也被用来做研究。协商是多agent系统中一种重要交互形式,近年来越来越多的人关注由agent构成的协商系统,Agent系统中基于agent的协商已经主要应用于B2B环境和解决Agent间的冲突,在以往基于agent的协商中,目标并没有被显式地定义和进行形式化的描述,而面向目标性又是agent的一个重要特性,也越来越多的被人们所关注本文简要介绍了协商的概念,对协商各个不同的类型也进行了分析。还对基于agent BDI模型下的协商目标进行研究,给出了目标的类型的定义,针对不同目标类型的agent协商过程,对协商过程中可能产生的不一致目标进行处理,说明了如何解决这种目标间的冲突。另外本文研究了现有基于目标的agent协商,给出了这种框架下的agent协商过程,描述了agent如何以目标为中心来进行协商,判定协商的成败,定义协商的优劣。通过对目标的显示定义,更加突出了目标在协商过程中的重要性。在自动协商中,通过使用目标有可能更快达到结果,具有较高的质量。同时agent对目标的追求,也体现了agent的理性行为,为agent在协商环境中提供新的判定标准。更多还原

【Abstract】 At present, artificial intelligence agent technology is increasingly becoming the focus of the study, and it has always been the definition of agent-based and conducted on a formal model to explore, but also there have been many great theories, most notably to the number of Rao and Georgeff s BDI model and the target as the BDI model has also been an important concept for research.Nogatiation is an important interaction forms of agent systems, this year more and more people are concerned about the composition of nogatiation by the agent system, Agent-based agent system has been mainly used in nogatiation B2B environment and to resolve the conflict between the Agent, in the past agent-based nogatiation, the goal has not been explicitly defined and formal description of the goal-oriented is an important characteristics of agent, but also been more and more attention.This paper introduces the concept of consensus on the different types of nogatiation are also analyzed. Also agent BDI-based model to study the objectives of the nogatiation, given the definition of the type of goals, the goals for different types of agent negotiation process of the consultation process may have to deal with inconsistent goals, how to address this goal conflict.In addition this paper, the objectives of the existing agent-based nogatiation, given that the agent under the framework of the nogatiation process, describing how the agent on the target as the center, to hold nogatiation to determine the success or failure of nogatiation, the definition of consensus is good or bad. By the definition of the goals display, a more prominent goals in the importance of the nogatiation process. In the auto-negotiation, through the use of goals to achieve results more quickly, with high quality. At the same time, the pursuit of the goal for agent, also reflects the agent’s rational behavior, the agent in the negotiations for the environment, provide new criteria.更多还原
