    Exploring a self organizing Multi Agent System for service discovery
    (CERIST, 2009-09) Mellah, Hakima; Drias, Habiba; Banarjee, Soumya; Hassas, Salima
    The paper presents a Multi Agent System (MAS) approach, for service discovery process to consider the user in the service discovery process involoving his interactions under constraints. The service discovery has become an emerging phenomena in software engineering and process engineering as well. The proposed MAS has demonstrated significant self oranizining potential. This feature is very crucial for assuring a correct service delivery, to avoid failures or mal-function for the service discovery environment. The requirement for self organizing choreographed services have been well realized, in case of operational, functional and behavioral faults. Self organization within the MAS is adopted by the recourse to a self organizing protocol conceived from bacteria colony and evolutinary computation paradigm.

    A formal approach for a self organizing protocol: Production System application
    (CERIST, 2009-10) Mellah, Hakima; Drias, Habiba; Hassas, Salima
    Any dysfunction in production system (PS) is likely to be very expensive; so modelling by Multi Agent Systems (MAS) makes the production system (PS) possible to have aspects of robustness, reactivity and flexibility, which allow the PS control to be powerful and to react to all the risks being able to occur. In order to have a fault-tolerant PS, we propose when and how to recourse to a self organizing protocol making the MAS capable of changing its communication structure or organization, and thus reorganizing itself without any external intervention.

    Toward a business process collaboration in E-commerce exchange using Web serice
    (CERIST, 2009) Khelifa, Lydia Nadia; Aklouf, Youcef; Drias, Habiba; Boumellil, Lamia Sabiha
    B2B e-commerce is an emergent area, which the profit of enterprises depend on its performance. Business Process collaboration is a challenge that companies are facing to. However, emergent specifications resulted from the convergence of web services and grid i-e Web Service Resource Framework (WSRF) open new horizon for the collaboration of business Processes. WSRF specifies a WS-Resource approach to model and manage state in a Web services context. In this paper, we present our vision of integrating WSRF in business process collaboration which is described through a collaborative Business Process defined by all participants. WSRF is used to virtualize and encapsulate the private Business Processes. The WS-Notification is used to notify about the state changes to coordinate participant Business Processes

    Découverte Des Grid Services Publiés Dans Des Registres Hétérogènes
    (CERIST, 2009-03) Boulkrinat, Nour El Houda; Aklouf, Youcef; Drias, Habiba
    L’environnement du grid est caractérisé par des ressources multiples et dynamiques, publiées dans des registres qui sauvegardent les informations relatives aux ressources, tel que : MDS (Monitoring and Discovery System) et GMD (Grid Market Directory). Il se trouve que parfois, les besoins des utilisateurs nécessitent d’autres ressources et applications publiées dans d’autres registres comme : UDDI (Universal Description Discovery and Integration) ou ebXML. La découverte et l’accès aux grid services publiés dans des registres hétérogènes, devient alors une tâche complexe. Cet article s’intéresse à la résolution de ce problème, à cet effet, nous proposons une approche de découverte qui permettra aux utilisateurs un accès transparent à ces registres sans se soucier de leurs structures.
