Unified Reversible Life Cycle for Future Interoperable Enterprise Distributed Information Systems

Best Paper AwardInternational audienceThis paper aims at improving the re-implementation of existing information systems when they are called to be involved in a system of systems, i.e. a federation of enterprise information systems that interoperate. The idea is reusing the local experiences coming from the development of the original information system with the process of Model Discovery and Ontological approach. We give first, a review of ongoing researches on Enterprise Interoperability. The MDA can help to transform concepts and models from the conceptual level to the implementation. The HLA standard, initially designed for military M&S purpose, can be transposed for enterprise interoperability at the implementation level, reusing the years of experiences in distributed systems. From these postulates, we propose a MDA/HLA lifecycle to implement distributed enterprise models from the conceptual level of federated enterprise interoperability approach. In addition to this classical development, we propose a model reversal methodology to help re-implement the legacy information system, in order to achieve the interoperability with other systems

Product-service systems scenarios simulation based on G-DEVS/HLA: Generalized discrete event specification/high level architecture

International audienceIn the past decade, personal customers expected manufacturing companies to provide them with a physical product with, nonetheless, some basic additional services. Currently, customers expect a more comprehensive solution, integrating both a physical product and non-physical services, which explains why companies have started to propose Product-Service Systems (PSS). The underlying objective of profitability can be attained if the system is designed, based on system use, to avoid waste, and if services are developed jointly with products. Although all the requisite conditions are well-known, the optimal way to satisfy them is not formalized or even guided by any clear methodology. This paper proposes to create PSS models to be simulated in different service scenarios based on G-DEVS/HLA. The simulation results provide pointers to help decision maker choose between several PSS design scenarios to be manufactured. A case study from the toy industry is used to illustrate the proposed methodology

Building a high-level architecture federated interoperable framework from legacy information systems

International audienceThis paper aims at improving the re-implementation of existing information systems when they are called to be involved in a system of systems, i.e. a federation of enterprise information systems that interoperate. The idea is reusing the local experiences coming from the previous development of the existing information system with the process of model discovery. To avoid redeveloping the entire system when the enterprise needs to cooperate with others, this approach proposes to create local interfaces to code and decode information. The interfaces are instantiated by using models discovered. The interfaces are developed in accordance with the high-level architecture (HLA) standard that proposes message interoperability and synchronisation mechanisms among distributed systems. First, this paper recalls the strong points of model-driven architecture (MDA)/architecture-driven modernisation methodologies for model transformation from conceptual level to implementation and the HLA standard. Then, a MDA and HLA framework is proposed to implement distributed enterprise components from the conceptual level through a federated enterprise interoperability approach. In addition, a model reversal methodology is developed under the framework to guide the re-implementation of legacy information systems to achieve desired interoperability with other systems. To extend the scope of the approach, implemented Web services are combined with HLA in order to facilitate the use of HLA in large distributed execution. This paper ends with an implementation example for validating the approach

Federated approach for enterprise interoperability (a reversible model driven and HLA based methodology)

L'interopérabilité est une des caractéristiques requises pour les entreprises évoluant dans un marché globalisé à la concurrence croissante et complexe. Dans la dernière décennie, l'interopérabilité des entreprises a été développée et prescrite par différents types de cadres, de méthodes et de techniques. Cependant, le développement de l'interopérabilité n'est pas encore assez mature pour être considéré en tant que science à part entière. Par ailleurs, il ne cesse d'évoluer en fonction des besoins des entreprises,de leurs environnements et des différents secteurs d activité. Aujourd'hui, l'environnement s organise en réseaux multipleet provoque d imprévisibles situations liées à leurs dynamiques (création, modification, résilience). Ainsi l interopérabilité durable devient une dimension nouvelle de recherche pour l'interopérabilité des systèmes d'entreprise et de leurs domaines d'applications. Dans l'interopérabilité durable, l'interopérabilité d'entreprise dynamique est l'un des thèmes focaux. Cette approche dynamique, également appelée fédérée , est originaire du cadre d'interopérabilité de l'Entreprise proposée dans le Réseau d Excellence (NoE)INTEROP. Il vise à donner la capacité aux entreprises d établir une interopérabilité à la volée sans connaissance préalable des informations à échanger. Cette thèse présente l'état actuel des travaux qui se rapprochent du développement de l'interopérabilité des entreprises fédérés en dynamique. Ces travaux de thèse mettent tout d abord en évidence l intérêt de la redécouverte de modèles à partir d un système existant avant de concevoir un futur système. Une méthodologie de réverse engineering dirigée par les modèles et basée sur la norme de simulation distribuée HLA est proposée pour concevoir et développerpar l'approche fédérée d'interopérabilité le futur système d information de l entreprise. La phase de mise en œuvre réutilise les concepts d interopérabilité issusde la simulation distribuée pour faciliter et coordonner la communication entre les systèmes d'information distribués hétérogènes des entreprises en combinant avec les dernières orientation service actuelle du web. La plate-forme tend ainsi à satisfaire les attentes de la dernière version du standard de l'architecture de haut niveau HLA 1516 Evolved. Ce cadre propose donc un cycle complet de développement pour qui a l'intention de réutiliser un système d'information existant sans recoder ex-nilo, mais en l adaptant aux nouvelles exigences de la dynamique d'interopérabilité.Interoperability is one of the requisite features for existing enterprises in the increasing competitive and complex global market. In the last decade, enterprise interoperability has been developed and prescribed by various kinds of frameworks, methods, and techniques. However interoperability development is still not mature enough to become a science. Meanwhile, it keeps evolving according to different business requirement and market environment. Nowadays, networked environment causes unpredictable dynamical situations, thus sustainable interoperability becomes a new research dimension in the interoperability of enterprise systems and applications domain. In the sustainable interoperability, enterprise interoperability dynamics is one of the focal topics. This dynamic approach also called federated is originated from Enterprise Interoperability Framework of INTEROP NoE, which aims to establish interoperability on the fly. This thesis presents current state on federated approaches to develop enterprise interoperability dynamics. Based on this study, a reversible model driven and HLA based methodology is proposed for achieving federated approach for Enterprise Interoperability. It reuses distributed simulation interoperability concepts to facilitate and coordinate the communication between heterogeneous distributed information systems of the enterprises. The platform is complaint with the latest version of the High Level Architecture (HLA) that is a distributed communication standard. This framework is also proposing a development lifecycle that intends to reuse existing information systems without recoding them but by adapting them to the new requirements of interoperability dynamics.BORDEAUX1-Bib.electronique (335229901) / SudocSudocFranceF
