Dynamic QoS evaluation for Web Services Using Data Envelopment Analysis on Real-time Status
Luda Wang, Peng Zhang · International Journal of Database Theory and Application · 2017
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.
