Experienced knowledge for the description of maintenance packages

The presented work is included in the research theme that specifies some means of capitalization and exploitation of knowledge from experience feedback processes in the context of industrial maintenance management. Our research on it is a more precise definition of the proposed project, built with a problem asking how to handle the management of repair packages. Upstream, the knowledge of various experts are materialized in the form of expert reports. Downstream maintenance wants to quickly repair products based on symptoms or change parts in advance. For this, we propose a methodology by analysing the feedback to improve the response time for maintenance services. This is implemented in the context of a manufacturing traction motors for the railway industry

A partir d une étude ethnométhodologique du "bug de l'an 2000", intégration d un processus d amélioration continue de gestion de bugs, incidents, problèmes, changements et configurations pour les systèmes d information critiques

L objectif de la présente thèse est de contribuer au débat suivant : comment gérer bugs, incidents, problèmes et changements qui apparaissent dans les grands systèmes d informations critiques ? On revient d abord sur les évolutions théoriques et technologiques du domaine. On traite ensuite des méthodologies récentes autour des référentiels (CMMI, COBIT, ITIL) qui visent à améliorer les méthodes de gestion d incidents, proble mes, configurations dans les aspects techniques, organisationnels et stratégiques. Une analyse comparative est effectuée avant d adopter une posture pragmatique faisant intervenir les spécificités en matière d intégration de technologies, de management de processus et d intégration des démarches d amélioration continue. Le travail débouche alors sur des nouvelles propositions, basées sur un modèle de pilotage par la connaissance, en matière de modélisation et de conduite de la gestion des problèmes. On décrit alors la conception et le développement d un logiciel qui démontre la faisabilité du modèle de pilotage proposé. Sa mise en place et son utilisation sur le terrain sont évalués afin de mesurer l opportunité et les limites d un tel système.ST DENIS-BU PARIS8 (930662101) / SudocSudocFranceF

Alignment of the product lifecycle management federated interoperability framework with internet of things and virtual manufacturing

International audienceThe emergence of the Internet of Things (IoT), coupled with other capabilities such as Cloud Computing and many others, creates opportunities for the development of Cyber-Physical Systems (CPS) at the scale of a digital business ecosystem. It will impact the way engineers work when designing, developing, deploying, operating, or maintaining complex systems-of-systems, with increasing needs concerning security, agility, and interoperability. The Federated Interoperability Framework (FIF) has been developed for Aeronautic Space and Defence over the last years to prepare and build continuous operational Product Lifecycle Management (PLM) interoperability. This paper aims at illustrating, defining, and demonstrating the required evolutionary nature of the FIF from its genesis, by describing past, last, and future evolutions, in particular for the PLM Standards testbed, Virtual manufacturing and CPS. Then Evolvability is defined and discussed, and the provided presentation of the FIF evolutions used to demonstrate its evolutionary nature, making the FIF contributing to the State of the Art and the State of the Practice

Aggregating Probabilistic Models of Complex Multi-State Systems

International audienceThis paper proposes an aggregating method based on a bayesian approach to improve the continuity of service for complex multi-state systems into an industrial context. In the study of our "equivalent" model of a given machines con_guration, each machine is considered as one bayesian multi-state sub-model. A simulation is made with or no learning on the node of maintenance policy for each con_guration of machines in order to study, master its process of degradation and suggest the best actions of maintenance policy over an given exploitation phase with regard to the chosen performance indicators

Digital factory system for dynamic manufacturing network supporting networked collaborative product development

International audienceDuring the last years, important research investments have been made by Airbus Group Innovations for the establishment of sustainable Product and Process data interoperability based on open standards. Driven successively by concurrent engineering, collaborative product design in the virtual enterprise or digital behavorial aircraft, it was capitalize through the establishment of a federative interoperability framework. Driven by factory of the future-related research, the dynamic manufacturing network (DMN) concept enriched the framework, which aims at providing agile infrastructure for networked collaborative product development. For such networks, protocols based on open eBusiness product lifecycle management (PLM) standards for exchange and sharing of product and process data between the implied organizations, their processes and the technical enteprise applications supporting these processes are needed This paper presents a new way of combining model-based enterprise platform engineering, model-driven architecture, and system engineering in order to adress the establishment of a sustainable interoperability within DMN. Based on relevant litterature interoperability issues, this paper describes the new approach, which relies on the association of effective existing technologies coupled with research results on the fields of model-driven engineering (MDE), enterprise interoperability, system engineering and PLM. The new approach relies on the concept of digital factory system (DFS) coupled with DMN in order to produce sustainable and agile collaborative infrastructure for manufacturing digital ebusiness ecosystem. The approach is then illustrated through use case coming from the IMAGINE project and an outline is provided on how it will be used and developed further for the assessment of PLM standards and their implementation in the Standard Interoperability PLM project at IRT-Systemx
