The service-oriented paradigm offers support for engineering service-based systems (SBSs) based on service composition where existing services are composed to create new services. The selection of services with the aim to fulfil the quality constraints becomes critical and challenging to the success of SBSs, especially when the quality constraints are stringent. However, none of the existing approaches...
The service-oriented paradigm offers support for engineering service-based systems (SBSs) based on service compositions. The selection of services with the aim to fulfil the quality constraints for SBSs and to achieve the optimisation goals is a critical and challenging issue. In particular, when the quality-of-service (QoS) constraints for a SBS are severe, it is often difficult to find an optimal...
SLAs play an important role for the QoS-driven service composition. Meanwhile, the temporal constraints are one of the main elements in the management of SLA especially in specifying the validity period of the QoS offers. In practice, the temporal constraints should be generated dynamically by taking the resource capability of the provider into account. The generation should consider various parameters...
