A qualitative approach for decision making under non-functional constraints during agile service composition

Service composition implementation, in a Web and business context, opens many investigation and improvements prospects. The contributions in this thesis are then intended to perform a particularly dynamic and flexible composition, able to take into account multiple non-functional constraints. They revolve around the concepts of active, useful and agile composition. Active composition is able to effectively complement dynamic approaches, in order to improve their capability to adapt to non-functional changes. It relies on a transposition of the late-binding principle to the SSOA context, then able to integrate the current QoS values of services at execution time. Useful composition is linked to our new LCP-net formalism for expressing user preferences. The elicitation of non-functional preferences, established between services QoS properties and their values, will afterward provide a total or almost total order over each candidate services sets, during service selection. Finally, agile composition is the “sum” of the last two, where we lay the groundwork for global QoS management during processes execution.
