摘要 为确保制造网格平台提供的各种制造资源及服务达到使用者的功能与质量要求,建立了制造网格服务质量管理系统。在该系统中,任务分解通过特征匹配和相似度搜索算法、服务质量约束分解、服务质量分解结果验证等过程实现;资源调度通过服务质量属性匹配,基于时间、质量、成本、服务和信誉度的多目标决策建模,以及容错处理等过程实现;资源预留采用基于预留策略和任务列表的方法实现;服务等级协议则通过服务等级协议协商、违约检测、违约赔偿以及服务等级协议中止等过程实现。制造网格服务质量的研究,贯穿产品开发、制造、管理和销售等整个生命周期,其成果直接影响制造网格的实用性,是制造网格从"研究"走向"应用"的一个重要环节。 Quality of Service management system was presented in Manufacturing Grid (MG-QoS) to guarantee the satisfactions from customers' on various manufacture resource & service requirements. With this system, task decomposition was implemented by characteristics matching, similarity degree searching algorithm, service quality re-striction decomposition and its results validation. The resource scheduling was carried out by QoS attributes' matching, TQCSR-based multi - objective modeling, and fault-tolerant handling. The resource reservation was a-chieved by defining reservation policies and accessing task - lists. And, the Service Level Agreement (SLA) was managed with the functions of SLA negotiation and creation, SLA deployment, violation detection, penalty management and SLA termination. This schema aimed to be one of the indispensable components of MG during the lifecycle of product manufacturing.
