  • An automatic model-to-model mapping and transformation methodology to serve model-based systems engineering

    Tiexin Wang, Sébastien Truptil et Frédérick Bénaben. « An automatic model-to-model mapping and transformation methodology to serve model-based systems engineering ». In : Information Systems and e-Business Management (9 juin 2016). P. 1--54. ISSN : 1617-9846, 1617-9854. DOI : 10.1007/s10257-016-0321-z.
    With enterprise collaboration becoming increasingly frequent, the ability of an enterprise to cooperate with others has become one of the core factors in gaining competitive advantage. This trend has led to an urgent requirement to improve cooperation ability. To this end, model-based systems engineering is being adapted so that it can be used to represent and simulate the working processes of enterprises. Model-to-model mappings and transformations, as important aspects in model-based systems engineering, have become two of the key factors in improving the cooperation capabilities of enterprises. However, the foundations for achieving automatic model-to-model transformation have not yet been built. Normally, model transformation rules are built on the basis of model mappings, and model mappings concern semantic or syntactic representations. One of the difficulties in achieving model-to-model mappings and transformations lies in detecting the semantics and semantic relations that are conveyed in different models. This paper presents an automatic model-to-model mapping and transformation methodology, which applies semantic and syntactic checking measurements to detect the meanings and relations between different models automatically. Both of the semantic and syntactic checking measurements are combined into a refined meta-model based model transformation process. To evaluate the performance of this methodology, we demonstrate its applicability with a realistic example.
  • Towards a better management of complex emergencies through crisis management meta-modelling

    Managing complex emergency situations is a challenging task, mainly due to the heterogeneity of the partners involved and the critical nature of such events. Whatever approach is adopted to support this objective, one unavoidable issue is knowledge management. In the context of our research project, gathering, formalising and exploiting all the knowledge and information about a given crisis situation is a critical requirement. This paper presents some research results concerning this specific topic: from a theoretical point of view, the generic dimensions of crisis characterisation are defined, while from a technical point of view, we describe a software solution able to collect that knowledge (based on meta-models and ontologies). This is used to confront the characteristics of the situation (context) with characteristics of the resources (relief system) in order to design a suitable response. Finally, an illustrative example concerning a crash between a tanker truck and a train is described.

  • Event-cloud platform to support decision-making in emergency management

    Matthieu Lauras, Frédérick Bénaben, Sébastien Truptil et Aurélie Charles. « Event-cloud platform to support decision-making in emergency management ». In : Information Systems Frontiers 17.4 (août 2015). P. 857--869. ISSN : 1387-3326, 1572-9419. DOI : 10.1007/s10796-013-9475-0.
    The challenge of this paper is to underline the capability of an Event-Cloud Platform to support efficiently an emergency situation. We chose to focus on a nuclear crisis use case. The proposed approach consists in modeling the business processes of crisis response on the one hand, and in supporting the orchestration and execution of these processes by using an Event-Cloud Platform on the other hand. This paper shows how the use of Event-Cloud techniques can support crisis management stakeholders by automatizing non-value added tasks and by directing decision-makers on what really requires their capabilities of choice. If Event-Cloud technology is a very interesting and topical subject, very few research works have considered this to improve emergency management. This paper tries to fill this gap by considering and applying these technologies on a nuclear crisis use-case.

  • Event-driven agility of interoperability during the Run-time of collaborative processes

    Anne-Marie Barthe-Delanoë, Sébastien Truptil, Frédérick Bénaben et Hervé Pingaud. « Event-driven agility of interoperability during the Run-time of collaborative processes ». In : Decision Support Systems 59 (mars 2014). P. 171--179. ISSN : 0167-9236. DOI : 10.1016/j.dss.2013.11.005.
    The modem business environment tends to involve a large network of heterogeneous people, devices and organizations that engage in collaborative processes among themselves. Given the nature of this type of collaboration and the high degree of interoperability between partner Information Systems, these processes need to be agile in order to respond to changes in context, which may occur at any time during the collaborative situation. The objective is to build a Mediation Information System (MIS), in support of collaborative situations, whose architecture must be (i) built to be relevant to the collaborative situation under consideration, (ii) more easily integrated into the existing systems, and (iii) sufficiently agile, through its awareness of the environment and of process events, and through the way it reacts to events detected as being relevant. To apply agility mechanisms, it is crucial to detect the significant events that will lead to a subsequent evolution of the situation (detection step). Event-Driven Architecture (EDA) is used to design the structure of the part of the system that is in charge of MIS agility. This architecture takes the events into account, manages them and, if needed, uses them to trigger the adaptation of the MIS. We have defined a means to monitor the evolution of the situation. If relevant changes are detected, and if the situation does not evolve in the expected way, an adaptation is proposed. It is concluded that the principles of detection and adaptation, combined with the responsiveness of the system (provided by the automation of transitions), and based on Event Driven Architecture principles, together provide the agility required for collaborative processes.

  • ISyCri

    Débuté le : 03/05/2007 Fini le : 02/02/2010
    ISyCri (Interopérabilité des Systèmes en situation de Crise) est un projet de recherche financé sur l’appel « sécurité » de l’ANR. Il concernait la gestion des situations de crise : caractérisation de ces situations, identification des processus de réponse, support de l’interopérabilité des SI des acteurs de la résolution de la crise (via la définition d’un SI Médiateur agile, adapté et adaptable à la situation). La participation du CGI dans ce projet concernait tout d’abord le rôle de coordinateur du projet.
