Abstract :
Assuring quality of service (QoS) properties is critical in service-oriented applications (SOAs) development. In this paper, we present an approach for specifying QoS properties on services and selecting services for their composition in a way that maximizes the QoS values. We apply the integration of concerns paradigm to allow combined specification of QoS and functional properties by using Quantitative Constraint Automata, and to integrate QoS aspects into service-oriented applications development processes, mainly for service selection and composition.
