摘　　要：为了尽可能地保证更多的网格应用在截止时间内完成,采用模糊统计法和最大隶属度原则计算出网格应用性能差率的门限,利用该门限对应用作出相应调整,部分解决了现有网格监控的不足。最后进行了仿真测试,从总运行时间和截止期内的完成率两个方面说明了该监控是有效的。To guarantee much more applications could be accomplished before deadline, fuzzy statistics and the biggest membership degree principle were introduced to compute the threshold of difference rate of grid application performance, on which to reschedule the tasks based. Partially supplied the gap of the grid monitoring. And experimental results of total runtime and completion rate of all tasks show that the scheme is effective.
