Blackboard Meets Dijkstra for Optimization of Web Service Workflows
share
This paper presents the integration of Dijkstra's algorithm within a Blackboard framework to optimize the selection of web services from service providers. In addition, methods are presented how dynamic changes during the workflow execution can be handled; specifically, how changes of the service parameters have effects on the system. For justification of our approach, and to show practical feasibility, a sample implementation is presented.
