Resource selection based QoS requirements in MG workflow

In manufacturing grid (MG) workflow, there are a large number of similar or equivalent resources provided by different third parties. It is not sufficient for a workflow management system to only consider functional characteristics of the workflow. The quality of service (QoS) requirements for execution also needs to be considered by MG workflow management system. In this paper, we have proposed a QoS oriented framework that is capable of conducting the adaptive selection process and simultaneously provides binding and execution of resources for the underlying workflow. To achieve these objectives, as the first step, we have designed a resource model, then, give the definition of QoS requirements of activity and develop an algorithm to select resources according to QoS parameters. An example has confirmed that the proposed framework and the algorithm are very effective in improving the MG Workflow system.
