Dynamic QoS evaluation for Web Services Using Data Envelopment Analysis on Real-time Status

Abstract

Service run-status monitoring can provide treal-time status for service QoS evaluation as service properties. In this work, dynamic QoS evaluation for Web services are based on DEA. Proposed methods could be used to analyze real-time status of Web services. DEA-based service performance evaluation is implemented by a multi-objective model, and DEA-based service QoS evaluation is implemented by a multi-objective model with critical real-time status performance. Both models are effective depending on particular argument and validation. Dynamic QoS evaluation for Web services are based on DEA could provide performance and QoS information to service composition.
