基于动态描述逻辑的多主体协作模型 总被引:7,自引:2,他引:7
基于动态描述逻辑的主体模型和协作过程就是既考虑了智能主体的知识表示与推理问题,又紧密地结合主体的设计与编程问题,把表示与推理应用到主体的具体设计中.它充分利用了动态描述逻辑的统一的形式化框架,同时从静态的知识表示与推理和动态的运行与变化两个方面来刻画主体的心智状态和协作过程,探讨了主体信念、行为能力、目标和规划等心智要素的表示、推理与修改以及联合目标的形成、多目标的规划问题.多主体协作模型将理论和实践有机地结合起来,能够充分体现智能主体的本质特征与运行机制,为多主体系统的设计与编程奠定了很好的基础. 相似文献

SPIN模型检测器主要用来检测线性时序逻辑描述的规范,而多智体系统的规范采用时序认知逻辑描述比较方便。本文着重讨论了如何利用SPIN模型检测线性时序认知逻辑的方法,根据局部命题的理论,将模型检测知识算子和公共算子表述的规范规约为模型检测线性时序逻辑的问题,从而使SPIN的检测功能由线性时序逻辑扩充到线性时序认知逻辑。本文通过一个RPC协议分析实例来说明模型检测线性时序认知逻辑的方法。 相似文献

In a multi-agent system, agents are carrying out certain tasks by executing plans. Consequently, the problem of finding a plan, given a certain goal, has been given a lot of attention in the literature. Instead of concentrating on this problem, the focus of this paper is on cooperation between agents which already have constructed plans for their goals. By cooperating, agents might reduce the number of actions they have to perform in order to fulfill their goals. The key idea is that in carrying out a plan an agent possibly produces side products that can be used as resources by other agents. As a result, an other agent can discard some of its planned actions. This process of exchanging products, called plan merging, results in distributed plans in which agents become dependent on each other, but are able to attain their goals more efficiently. In order to model this kind of cooperation, a new formalism is developed in which side products are modeled explicitly. The formalism is a resource logic based on the notions of resource, skill, goal, and service. Starting with some resources, an agent can perform a number of skills in order to produce other resources which suffice to achieve some given goals. Here, a skill is an elementary production process taking as inputs resources satisfying certain constraints. A service is a serial or parallel composition of skills acting as a program. An operational semantics is developed for these services as programs. Using this formalism, an algorithm for plan merging is developed, which is anytime and runs in polynomial time. Furthermore, a variant of this algorithm is proposed that handles the exchange of resources in a more flexible way. The ideas in the paper will be illustrated by an example from public transportation. 相似文献

In order to develop a proof procedure of multi-agent autoepistemic Logic (MAEL), a natural framework to formalize belief and reasoning including inheritance, persistence, and causality, we introduce a method that translates a MAEL theory into a logic program with integrity constraints. It is proved that there exists one-to-one correspondence between extensions of a MAEL theory and stable models of a logic program translated from it. Our approach has the following advantages: (1) We can obtain all extensions of a MAEL theory if we compute all stable models of the translated logic program. (2) We can fully use efficient techniques or systems for computing stable models of a logic program. We also investigate the properties of reasoning in MAEL through this translation. The fact that the extension computing problem can be reduced to the stable model computing problem implies that there are close relationships between MAEL and other formalizations of nonmonotonic reasoning. 相似文献

1 引言对策论的研究是以每个Agent的效用和赢利为基础的,每个Agent都希望能够在协商过程中求得Nash平衡的策略组合,使得那些基于理性假设的Agent均可获得一个稳定并且满意的解。当任何理性Agent达到Nash平衡点后,它们都不会试图离开,这是因为只有Nash平衡点,才能获得较大的赢利。可惜的是,Nash平衡不一定总是存在,或者可能存在多个,在这些情况下,如何寻找满意解,是人们一直试图解决的 相似文献

Organizational models have been recently used in agent theory for modeling coordination in open systems and to ensure social order in multi-agent system applications. In this paper, we propose the employment of Organization Theory for the analysis and design of multiagent systems. Thus, we first discuss the current state of the art of organization-oriented multiagent system methods, placing emphasis on their organizational features. We also review human organizational structures, and we propose several guidelines for implementing agent organizations by means of Organization Theory. Our final aim is to employ well-known human organizational structures to develop multiagent systems. 相似文献
