Research Field "Optimization of Prozesses"
Due to the dynamic and heterogeneous nature of the Grid, the optimized selection of resources and services is not easy. Indeed, optimized resource selection should allow to discover on the fly the most suitable component services that can be orchestrated for delivering the composed workflow process. However, this is not always possible, because the selection should rely on advanced monitoring and performance analysis of workflows and should be based on QoS criteria that often are not available. Moreover, it should be taken into account that resources and services can be available/unavailable at runtime and at a particular point in time.
Hence, optimization and/or failure handling strategies commonly adopted in static environments might not be optimal. Therefore, this is another important problem, closely related to robustness, availability, and reliability issues, that must be considered.
