In this paper, we consider a provider that offers an application implemented as a composite service to several users with (possibly) different Quality of Service (QoS) requirements. To this end, the provider negotiates with both the clients and the service providers Service Level Agreements (SLAs), which define the respective QoS-related obligations along with the interval of time over which such obligations are to be met.
