摘要： 针对网格环境中资源节点的动态性容易导致网格任务执行失败的问题，提出一种基于模糊逻辑的网格节点可靠性评估模型。该模型综合考虑网格节点的CPU、网络和内存3种资源的可用性，利用模糊逻辑来推断网格节点执行任务的成功概率。设计基于模糊逻辑的网格节点可靠性评估模型的任务调度实验，实验结果表明该模型能够较好地评估网格节点可靠性，并能改进任务调度的性能。

Abstract: For the dynamic resources of grid nodes result in failure of task execution in the grid environment, a reliability evaluation model for grid nodes is proposed. The model takes the usages of CPU, memory and network into account, uses fuzzy logic to deduce the probability of successful task execution of grid nodes. Experimentation is designed to use the model for task scheduling. The results demonstrate that the model not only makes a good evaluation of grid nodes reliability, but also improves task scheduling performance.
Key words: grid computing, reliability, fuzzy logic
