摘要： 在网格服务发现和选择过程中，如何根据请求方（用户）对服务质量的需求，以及网格QoS的动态变化选择网格服务是一个重要问题。该文基于请求方（用户）对不同网格服务QoS赋予的权重不同以及容忍度不同，提出了网格服务选择算法，从而使得请求方（用户）获得的网格服务的性价比最高。

Abstract: In the process of discovery and selection of grid service, it is a key issue that how to select grid services according to varied clients’ demand and dynamic changes of grid QoS. A grid service selection algorithm based on varied QoS priorities is proposed. The grid service with higher ratio of performance to price could be obtained according to the computation.
