多Agent系统中软构件的动态绑定机制及其操作语义 总被引:2,自引:1,他引:2
近年来,越来越多的以计算机网络为平台的应用系统表现出自主性、动态性、开放性和异构性的特点,这使得软件开发理论和技术需要从软件体系结构的角度对这类系统的开发提供支持.面向Agent的软件开发技术提供了高层和自然的抽象方式对软件系统进行分析和设计,但现有面向Agent的方法学将Agent Class或者Agent Type视为多Agent系统软件体系结构的软构件,与Agent之间的关系仅仅是实例化的关系,这难以满足复杂系统对动态性的需求.从软件体系结构的角度上分析了多Agent系统中软构件的形式和机制,将Caste作为软构件,并以此为基础提出了Caste与Agent之间的动态绑定关系,定义了支持该机制的4个基本操作:join,quit,activate和inactivate及其操作语义,用以来指导多Agent系统软件体系结构的设计和实现. 相似文献

Software agents are associated with modern industrial software. In various application fields such as e-business, telecommunications, logistics, and industrial automation, software based on agents seems to make the challenges in modern applications easier to overcome. However, it's often unclear what a software agent is and why problems can be better solved with it. Is it concerning a technology, an architecture, or a programming concept? This article presents a general introduction to software agent concepts from the software engineer's perspective, explaining the theoretical basis and clarifying to which type of problem software agents might represent a reasonable approach. 相似文献

Current complex engineering software systems are often composed of many components and can be built based on a multiagent approach, resulting in what are called complex multiagent software systems. In a complex multiagent software system, various software agents may cite the operation results of others, and the citation relationships among agents form a citation network; therefore, the importance of a software agent in a system can be described by the citations from other software agents. Moreover, the software agents in a system are often divided into various groups, and each group contains the agents undergoing similar tasks or having related functions; thus, it is necessary to find the influential agent group (not only the influential individual agent) that can influence the system outcome utilities more than the others. To solve such a problem, this paper presents a new model for finding influential agent groups based on group centrality analyses in citation networks. In the presented model, a concept of extended group centrality is presented to evaluate the impact of an agent group, which is collectively determined by both direct and indirect citations from other agents outside the group. Moreover, the presented model addresses two typical types of agent groups: one is the adjacent group where agents of a group are adjacent in the citation network, and the other is the scattering group where agents of a group are distributed separately in the citation network. Finally, we present case studies and simulation experiments to prove the effectiveness of the presented model. 相似文献

Law-abiding and integrity on the Internet: A case for agents 总被引:1,自引:0,他引:1
Frances Brazier Anja Oskamp Corien Prins Maurice Schellekens Niek Wijngaards 《Artificial Intelligence and Law》2004,12(1-2):5-37
Software agents extend the current, information-based Internet to include autonomous mobile processing. In most countries such processes, i.e., software agents are, however, without an explicit legal status. Many of the legal implications of their actions (e.g., gathering information, negotiating terms, performing transactions) are not well understood. One important characteristic of mobile software agents is that they roam the Internet: they often run on agent platforms of others. There often is no pre-existing relation between the “owner” of a running agent’s process and the owner of the agent platform on which an agent process runs. When conflicts arise, the position of the agent platform administrator is not clear: is he or she allowed to slow down the process or possibly remove it from the system? Can the interests of the user of the agent be protected? This article explores legal and technical perspectives in protecting the integrity and availability of software agents and agent platforms. 相似文献
