Abstract :
In a service-oriented system (SoS), service requests define tasks to execute and quality of service (QoS) criteria to optimize. A service request is submitted to the service selector in the SoS, which allocates tasks to the service that can ´best´ satisfy the given QoS criteria. When the selector cannot optimize simultaneously the given QoS criteria, users need to specify priorities and preferences over the said criteria. Accounting for users´ QoS priorities and preferences is therefore necessary during service selection.
