摘要： 面向服务的网格系统需要有充分的服务质量(QoS)支持，比较QoS参数进行网格服务发现与选择，尽快达成服务的匹配，是保证用户QoS需求的有效方法。为描述网格服务的质量需求，该文定义了网格服务的基本QoS参数，提出了网格服务质量数SQN的新概念，用于度量网格服务的整体量化特性。在此基础上，提出了相应的服务匹配策略和价格确定模型，加快网格服务匹配的过程，保障用户服务质量，并作了较深入的分析与讨论。

Abstract: Service-oriented grid system requires an underpinning quality of service(QoS) support. To guarantee users’ QoS requirements, an effective method is to discover and select grid services using QoS properties. This paper defines some basic QoS parameters to describe quality requirements of grid service, and puts forward a new concept, the service quality number(SQN). As the one of all QoS parameters, SQN can represent a profile of one grid service’s quality. To expedite matchmaking process and satisfy users’ QoS request, the matchmaking strategy and price model are proposed, the computation results indicate a good performance. Corresponding discussion and analysis are carried through.
