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 an automated service composer in the SoS, which allocates tasks to those
service that, together, can “best” satisfy the given QoS criteria. When the composer cannot optimize simultaneously
the given QoS criteria, users need to specify priorities over the said criteria. Accounting for users’ QoS priorities is
therefore necessary during service selection. Once specified by the requester, quality properties will be used by the
composer to lead autonomic optimization of the service selection process. We outline and test a selection approach
that accommodates priorities and that is based on available Multi Criteria Decision Making techniques.
