中文摘要：
为了加快服务质量参数匹配过程，确保匹配成功，定义了一个新的服务质量参数——服务质量数，用于度量服务的整体质量特性。基于这个新的参数，提出服务请求分类匹配的思想和模糊匹配策略，避免了复杂的参数比对。试验结果表明，该策略取得了较好的性能。对于服务质量参数中的价格因素，为减小用户和服务提供者之间的分歧，基于纳什均衡理论提出了一个服务价格的确定模型，用来加快价格参数的匹配过程，最终的计算结果与试验结果吻合良好，确保了该模型的有效性和可行性。
英文摘要：
To speed up Quality of Services （QoS） matching process and guarantee successful matching, a new QoS parameter of Service Quality Number （SQN） was defined for a Grid service to depict the overall quality characteristics. Based on this new parameter, an idea of service matching according to different requests and the strategy of fuzzy matching were presented, which could avoid complex parameter comparison. The experimental data revealed a better performance. To reduce the divergence about price between service providers and users, a price model was put forward based on the theory of Nash equilibrium. The model could be used to expedite price matching, and the final computation results agreed with the experimental data. Finally, the effectiveness and feasibility of the model were guaranteed.
