Adaptive Workflow-Policy Based Management Scheme for Advanced Heart Disease Identification

Workflow management systems (WMS) in Grid computing are becoming more important to solve the sophisticated problem such as genomic analysis, drug discovery, disease identification, etc. In this paper, we discuss how to guarantee different user requirements according to user SLA in Grid workflow management system. An adaptive workflow management system for Quality of Service (QoS) constrained medical Grid application is designed and implemented to provide QoS awareness WMS and is applied to Physio-Grid e-health platform to identify human heart disease. The experimental result shows that the proposed system can flexibly enhance the Physio-Grid platform in terms of SLA guarantee of different user.
