Web services are modular, self-describing, selfcontained, platform-independent software components that can be published by service providers over the Internet. Web service composition (WSC) is the task of combining a chain of connected single services together to create a more complex and value-added composite service. For those web services providing the same functionality, quality of service (QoS) has been mostly applied to represent their nonfunctional properties and differentiate them for service composition, these approaches do not guarantee finding a solution satisfying the global QoS constraints for a composition task, even if there exists one under a different workflow. In this paper, we propose and validate DoWSS, a doubly weighted algorithm for service traffic shaping. We show via simulation that DoWSS possesses several advantages: It eliminates the approximation issues, prevents starvation, and contains the rapid credit consumption issue in existing credit-based approaches.Index Terms-quality of service, DoWSS, Web service composition, 978-1-4673-9781-0/15/$31.00 © 2015 IEEE 2015 Online International Confernece on Green Engineering and Technologies (IC-GET 2015)

“…In [9], time, cost, and reliability are of concern in the QoS model and a distance function-based multi-objective evolutionary algorithm is used to find an optimised composition. A QoS reference vector is proposed in [10] to model price, time, reliability, trust (i.e. subjective rating), and security.…”

Abstract. In service composition, quality of service is a major criterion for selecting services to collaborate in a process flow to satisfy a certain quality goal. This paper presents an approach for service composition which considers QoSbased service provision schemes and variability of the QoS when planning. The QoS of a service can be stated in terms of complex service provision schemes, e.g. its service cost is offered at different rates for different classes of processing time, or its partnership with another service gives a special class of QoS when they operate in the same plan. We also address that it is desirable for service planning to result in a plan that is durable and reusable since change in the plan, e.g. by deviation of the actual QoS, would incur overheads. Our planning approach takes into account these dynamic situations and is demonstrated by using the Estimation of Distribution Algorithm.

“…Research in [65,39,19,4,66,58,18] solves the QoS aware service selection problem. They assume the work plan is pre-defined and each task in the plan is not a concrete service but representing a service class with multiple candidates of different QoS measures.…”

Automated semantic web service composition is one of the critical research challenges of service-oriented computing, since it allows users to create an application simply by specifying the inputs that the application requires, the outputs it should produce, and any constraints it should respect. The composition problem has been handled using a variety of techniques, from Artificial Intelligence (AI) planning to optimization algorithms. However no approach so far has focused on handling three composition dimensions simul
