摘要
针对网格计算环境中网格资源的划分及调度问题,应用较完备的模糊数学理论和一个实例详细介绍了一种网格资源的划分及调度方法.其间使用的主要方法有:引入了数据标准化方法,以消除量纲的影响;采取了一种先综合考虑各项指标再分别处理的方法,以先期避免"木桶效应";针对有些文章中仅依靠模糊相似矩阵来进行资源划分的错误进行了纠正,最后的划分应该使用模糊等价矩阵.
This paper introduces a method, which divides the Grid Resources on Fuzzy Mathematics in de- tail. Firstly, the data standardization is applied to eliminating the effects of the different dimensions. Secondly, the method considers the Calculate Performance and Communication Performance in the same time at the beginning to avoid the wooden barrel effect at the first possible moment. Finally, aiming at the faet that in some articles, the Fuzzy Similar Matrix is applied to dividing the Grid Resources, this paper uses the Fuzzy Equivalence Matrix to divide the Grid Resourees rather than the Fuzzy Similar Matrix because it holds that there is no theoretieal basis for the Fuzzy Similar Matrix to be able to divide Grid Resources, but only the Fuzzy Equivalence Matrix ean do this.
