摘要: 针对网格中同类型不同版本资源所提供服务质量(QoS)的多样性,对用户从这一类型资源中选择具体资源造成困难的问题,提出了基于模糊筛选的资源选择策略。根据用户评价历史信息对资源进行模糊划分,建立资源版本评价矩阵,进行模糊筛选。实验结果表明,该策略较好地解决了用户需求和资源匹配问题,提高了用户的满意度。

Abstract: The Quality of Service (QoS) provided by the different resources with the same type is various, so it is difficult for the users to select the appropriate resource from this kind resources. The authors proposed a resources selection approach based on fuzzy selection. According to the history information, this method divided the resources fuzzily, built the evaluation matrix and selected the resources fuzzily. The simulation results show that the algorithm resolves the matching problem between the users' requests and the resources, and increases the users' satisfaction.

Key words: grid, fuzzy selection, resource selection, evaluated matrix
