Policy-based hybrid workflow management system for advanced heart disease identification

As computer and network technology grows, medical application is become more complex to solve the physiological problems within expected time. 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. Although existing WMS can provide basic management functionality in grid environment, consideration of user requirements such as performance, reliability and interaction with user is missing. In this paper, we discuss how to guarantee different user requirements according to user SLA in Grid workflow management system. A hybrid workflow management system for QoS constrained medical grid application is designed and implemented to provide QoS awareness WMS. The proposed system is applied to physio-grid e-health platform to identify human heart disease with ECG analysis and virtual heart simulation (VHS) workflow applications. The experimental result shows that the proposed system can flexibly enhance the physio-grid platform in terms of SLA guarantee of different user.
