QoS-aware, Optimal and Automated Service Composition with Users' Constraints

In order to address a fundamental issue of automated service composition, this paper presents a novel approach for QoS-aware, optimal and automated service composition with users' constraints. Firstly, we construct the workflow of service composition automatically, according to users' service request. And then, we propose an Enhanced Genetic Algorithm to select the QoS-aware, optimal service composition, considering not only the QoS constraints but also the composing consumption constraints for the first time. With our approach, the result of service composition can meet different users' needs in various scenarios. The experiments validate correctness, significance and scalability of the approach.
