Une approche orientée utilisateur pour la supervision des orchestrations de services

Abstract : Quality of Service (QoS) is an important issue today in the developement of software applications, especially in the context of Service-Oriented Architectures (SOA). The work of this thesis focuses on QoS supervision of service-oriented applications, defined as service orchestrations. The proposed supervision approach is generic. It is based on workflow control-flow patterns, which can be entirety or partillay implemented by any service orchestration language. On the other hand, it does not make any restrictions, neither on the monitored QoS attributes , nor on their representations. This supervision approach is based on a user-oriented preferences model, that represents faithfully the user satisfaction. The satisfaction degree derived from the preferences model is a high-level information representing the overall quality of the orchestration. New monitoring strategies are proposed on the basis of this satisfaction degree in order to satisfy user expectations. The elaboration of the preferences model uses the MACBETH method extended to the 2-additive Choquet integral operator as a multi criteria decision aiding method. An illustration of the approach is carried out on a service orchestration representing a Manufacturing Execution System (MES) process. This work was realized in a R&D project involving seven software vendors in the field of MES.STAR
