网格服务QoS动态评估方法研究

A study of QoS dynamic elaluation approach for grid service

提出了一种可扩展的网格服务QoS参数构造模型,定义了网格服务多维QoS参数的效用更新函数,且提出了网格服务QoS动态评估框架,并给出了相应的评估算法,用仿真实验验证了所提算法的有效性。

we propose the scalable structure model of grid service QoS parameters and define utility renewal functions of grid service multi-dimensional QoS parameters.Furthermore,we present a dynamic evaluation framework of grid service QoS and give its evaluation algorithms.The experiment and the analysis show the effectiveness of the algorithm.
