摘要: 为提高制造网格(Manufacturing grid, MGrid)系统中资源调度的成功率和有效性,减少用户选择最佳资源的时间,设计开发MGrid资源优选系统。针对当前MGrid资源管理和调度与资源服务信任相分离的缺陷,阐述资源服务信任QoS概念及其在整个MGrid资源管理和调度中的重要地位和作用,分析MGrid系统中资源供需双方在进行资源服务交易时存在的信任问题。在此基础上,建立包括域内和域间资源服务信任QoS评估的两层结构的MGrid资源服务信任评估模型,并给出该模型中资源服务信任评估具体量化算法、信任值的实时动态更新算法。对所提出的模型和算法进行试验验证,结果表明所提出的模型和算法能有效地提高MGrid系统中资源调度的成功率和有效性。

Abstract: In order to enhance the validity and successful rate of resources scheduling in manufacturing grid (MGrid) system, reduce the decision-making time of selecting the optimal resource service and improve the quality of service (QoS) in MGrid, the re-sources optimal-selection system is developed. The concept of resource service Trust-QoS and the important roles played in resource management and scheduling in MGrid are presented, as well as the trust problems exist in the resource service Trading between resource service demanders (RSD) and resource service providers (RSP). A two-layer resource service Trust-QoS evaluation model is put forward, which includes Trust-QoS evaluation model in the same resources domain and the Trust-QoS evaluation model in different resources domain, and the quantitative Trust-QoS value are proposed and detailedly described, as well as the real-time and dynamic updating algorithm. The experiment results show that the pro-posed model and algorithms are effective and useful.
