为了保障网格资源的利用率和实现资源主动分配,提出基于FIPA(FoundationofIntelligentPhysi-calAgents)英式拍卖和荷兰式拍卖协议的网格资源分配方法,在多Agent开发平台JADE(JavaAgentDevelop-mentFramework)下分别对这两种拍卖协议作了实现,给出了具体的实现算法、步骤、参与拍卖的各Agent的交互过程以及拍卖结果。最后,用实例说明了仿真实现过程的正确性。 相似文献

拍卖方法引入多Agent系统 总被引:5,自引:0,他引:5
Auction, an operational and effective resource allocation method, generally results in economical efficiency allocation between buyers and sellers. As a negotiation method, auction can be used in Multi-Agent Systems. Withthe consideration of computation ability and communication ability of agents, superadditive and subadditive property of goods, requirements of agents' revenue and real-time ability, proper auction methods can be selected to achieveone-many or many-many task assignments or resource allocation. In this paper, we systematically summarize bidingrules, buyers and sellers' strategies and the performances of current auction methods. A formal auction model, whichfits most of the current auction methods, is also presented. 相似文献

基于多Agent的主动数据仓库的研究 总被引:3,自引:4,他引:3
传统的数据仓库只能分析历史数据且数据抽取周期过长,极大地降低了企业的应变能力。实时数据仓库的出现改变了这个局面。以此为基础的基于多Agent系统的四层数据仓库体系结构(MART-DW),一方面提高了数据仓库的主动性和实时性,另一方面也增强了系统的伸缩性,能够更加有效地管理分布式集成环境。 相似文献

网格资源分配是网格计算中的关键问题之一,引起网格研究者越来越多的关注。网格资源分配的过程就是任务与资源映射的过程。在分析已有的网格资源分配方法的基础上,首先提出了一种基于Agent的网格资源管理模型,主要由用户层、客户服务层、信息服务层、区域管理层和资源层组成。在此基础上对基于Agent联盟的网格资源分配方法进行了研究,最后给出了实例分析。 相似文献

Resources in the grid context belong to different control organizations with different interest, therefore the economic interest
of each grid participant should be considered. The economic mechanism can guarantee the interest of participants in the grid
with fairness and efficiency. In this paper, an economic-based resource management framework is put forward for grid computing,
and then how to determine the price of resources with the economic mechanism is studied. A general equilibrium method is presented
for general resources and a double auction method is proposed for special resources in the grid environment, respectively.
Simulations are performed and experimental results indicate that the two methods are effective for corresponding application
scenarios.

We present algorithms, methods, and software for a Grid resource manager, that performs resource brokering and job scheduling in production Grids. This decentralized broker selects computational resources based on actual job requirements, job characteristics, and information provided by the resources, with the aim to minimize the total time to delivery for the individual application. The total time to delivery includes the time for program execution, batch queue waiting, and transfer of executable and input/output data to and from the resource. The main features of the resource broker include two alternative approaches to advance reservations, resource selection algorithms based on computer benchmark results and network performance predictions, and a basic adaptation facility. The broker is implemented as a built-in component of a job submission client for the NorduGrid/ARC middleware. 相似文献
