摘要
为确保制造网格平台提供的制造资源及服务能够达到使用者的功能与质量要求,建立了基于SLA的资源管理模型,并对模型中的资源调度算法进行了深入研究。该模型以制造资源的服务质量(QoS)属性为评价标准,以服务水平协议(SLA)为约束条件,通过资源调度方法和策略为消费者提供有质量保证的制造服务。最后,以快速成型制造为应用,验证了模型的实用性及资源调度算法的可行性。
To meet the consumers' demand on functions and qualities of manufacturing service provided in Manufacturing Grid (MG), a SLA-based Resource Management Model was constructed, as well as an algorithm for resource scheduling in this model. Regarding QoS properties of manufacturing resources as assessment criteria, Service Level Agreement (SLA) as constraints requirement, qualified manufacturing services are provided through utilizing resource scheduling approaches and policies. In the end of this paper, application on rapid prototype manufacturing was taken as an example to illustrate the utility and feasibility of this model.
