L'articolo "A framework for QoS-aware binding and re-binding of composite web services", scritto da Gerardo Canfora, Massimiliano Di Penta, Raffaele Esposito, e Maria Luisa Villani, e pubblicato su JSS - Journal of Systems and Software, Volume 81, Issue 10, 2008, Pages 1754-1769, risulta nei “Top 10 Cited”, (i 10 articoli più citati tra quelli pubblicati negli ultimi 5 anni).


Di seguito l'abstract dell'articolo:
QoS-aware dynamic binding of composite services provides the capability of binding each service invocation in a composition to a service chosen among a set of functionally equivalent ones to achieve a QoS goal, for example minimizing the response time while limiting the price under a maximum value.
This paper proposes a QoS-aware binding approach based on Genetic Algorithms. The approach includes a feature for early run-time re-binding whenever the actual QoS deviates from initial estimates, or when a service is not available. The approach has been implemented in a framework and empirically assessed through two different service compositions.


The Journal of Systems and Software publishes papers covering all aspects of programming methodology, software engineering, and related hardware-software-systems issues. Topics of interest include, but are not limited to, software development environments and tools, techniques for developing, validating, and maintaining software systems, software architecture and design, global software development, service orientation, agile approaches, mobile, multiprocessing, real-time, distributed, concurrent, and telecommunications systems, software metrics, reliability models for software, performance issues, and management concerns. The journal publishes research papers, state-of-the-art surveys, and reports of practical experience. All articles should consider the practical application of the idea advanced through case studies, experiments, or systematic comparisons with other approaches already in practice. Occasionally, special issues are devoted to topics of particular interest; proposals for such issues are invited.
