Study on manufacturing grid resource service QoS modeling and evaluation

Current research on manufacturing grid (MGrid) systems has mainly concentrated on its concept, architecture, application prototype platform, and application foreground. Absent from the trend is the quality of service (QoS) of MGrid, such as QoS modeling, QoS evaluation, and QoS-based scheduling, which play a very important role in MGrid resource management. The related topics about MGrid and QoS are investigated in this study. The characteristics of QoS associated with its management requirements in MGrid are then further studied. Classification and modeling of MGrid QoS are investigated from three different perspectives: QoS whole-lifecycle management, MGrid architecture view, and QoS attribute parameters. The measurement and evaluation models of QoS parameters in MGrid are presented. A simple case study is described to illustrate how the proposed works can be applied to MGrid resource service management.
