多agent系统中agent的行为决策

The behavior decision of agent in multi-agent system is dependent on the task of individual agent ,the cooperation with other agents,and the multi-agent system' constraints. The paper presents three abstract concept models of achievement intention,joint intention and maintenance intention representing the factors that affect agent's behaviors respectively,to investigate autonomous agent's behaviors decision in support of agent-oriented software development. The paper discusses and analyzes how they will affect agent's behavior decision and the relationship among them,defines their formal and rigorous semantics,finally specifies and proves a number of important properties.

面向服务组合的主动Agent聚合框架及仿真实验分析

Web服务的组合需要聚合足够多的能满足服务请求的元服务,由服务请求者自己来查找这些需要的服务是目前SOA的常用方法,但这种方法没有考虑服务本身作为主体也有主动推销服务的意愿。为此提出了一个面向服务组合的主动服务聚合框架,引入Agent作为Web服务的代理可以将服务抽象地封装成一个可以主动发现服务请求的智能实体,通过"意图-行为-实现"机制实现了服务能力与服务请求的匹配。最后通过一个仿真程序上的几组实验数据分析和讨论了聚合框架的性能,验证了该方法的可行性。

Agent-Based Data Mining Framework for the High-Dimensional Environment

An agent-based data mining framework for the high-dimensional environment is built instead of the style of classical structural programming or the object-oriented programming. The framework supports the whole process of data mining of the high-dimensional environment. Belief-desire-joint intention agents are designed to fit the characteristic of the high-dimensional environment. At the same time, the syntax, semantics and reasoning rules of the agents are given. In the data mining system of the high-dimensional environment, agents need exchange messages. The cooperation behavior mechanism is adopted to complete the communication through the three-level pattern among agents that have their own fixed roles.

多主体团队交互协议

团队是动态不可预测性环境下协作问题求解的有效方式,联合意图是团队联合求解的关键.因此,主体在团队活动中如何采用言语动作形成、维护、解除联合意图,是一个值得研究的重要问题.旨在设计一种基于主体通信语言FIPA(foundation for intelligent physical Agent) ACL(Agent communication language)的多主体团队交互协议.首先,分析了现有FIPA ACL支持团队联合求解的充分性问题.在概念上明确区分了联合请求与委托请求,指出委托请求言语动作不能充分支持团队协作.并扩展定义了联合请求,讨论了相关定理.然后,基于联合请求动作,提出一种主体团队交互协议,并给出了协议的形式化语义,最后讨论了协议的实际应用.区别于现有的基本动作请求协议、合同网协议以及拍卖协议,团队交互协议描述了另一类主体交互模式,对主体交互模块的设计具有指导意义.

多播在数字监控系统中的应用

This paper discusses problems of multicasting and its application. Two ways are proposed to overcome theproblems of multicasting according to the architectures of current networks and the functional requirements of asurveillance System. One is that Winsock API is directly used to implement multicasting on a network supportingmulticasting. The other adopts the technology of proxy server and tunneling on a network not supporting multicast-ing. In addition,this paper discusses some techniques of multicasting,such as sending,resending,auto-adjusting withthe change of the transmission quality of networks,and the management of multicast group and multicast addresses.
