    An evolution process for service-oriented systems
    (Wydawnictwa AGH, 2012) Zalewski, Andrzej; Szlenk, Marcin; Kijas, Szymon
    Evolution of service-oriented systems is quite a new research area, which becomes more and more important as engineering challenges move from enabling service-orientation onto the maintenance and evolution of already developed service-oriented systems. However, the development of suitable evolution processes and methodologies is still an open research problem. The evolution process presented in this paper has been designed to address the evolution of service-oriented systems, which are technically built out of a set of service compositions. The presented process comprises phases and tasks compliant with ISO 20000. The underlying model of service-oriented system consisting of business processes and corresponding service composition models has also been presented. A traceability model and tools supporting change impact analysis have also been provisioned for. Preliminary industrial validation indicates that the evolution process should be easy to adapt by the industry.

    Koncepcja zastosowania podejścia agentowego w systemach SOA
    (Wydawnictwa AGH, 2009) Cetnarowicz, Krzysztof; Dyduch, Tadeusz; Koźlak, Jarosław; Żabińska-Rakoczy, Małgorzata
    In the paper, an overview of the research domain as well as tools related to development of SOA systems based on automatic composition of Web Services is presented. The concept of applying multi-agent approach in such systems and a project of its architecture are given. The domains of implemented pilot realisations are shown.
