De la modélisation des situations de travail à la caractérisation des compétences : Une approche par logique floue.

National audienceTo cope with the fast change of the technological and organizational context design managers nedd tools to help them to improve competence management. Our contribution aims at supporting the task of competence characterization that is considered as the first step of the competence management process. The proposed characterization approach involves two stages. The first stage concerns the qualifications of the working situation characteristics. The second stage is realized by a fuzzy logic system which converts the result of the step of "qualification" into an estimated value of the components of the associated competence. The application of the method in an industrial cas confirms the possibility of using this "principle of solution" to provide a dynamic characterization of competencies

Démarche de modélisation d'une situation de conception collaborative.

Le caractère collectif des activités de conception nécessite le développement de méthodes et d'outils pour la maîtrise des processus de conception et des activités collaboratives. Le groupe de travail est assimilé à un système constitué d'entités en interactions de différentes natures et régi par des mécanismes de régulation et de coordination. Nous nous intéressons ici à la modélisation d'une situation collaborative. Après une définition de la situation et la description de différentes perceptions de ce concept, nous proposons un modèle de situation dans lequel nous caractérisons les entités de différentes natures qui sont en interactions. Une classification des relations entre ces entités est proposée. Les perspectives de ce travail sont de contribuer à l'amélioration d'outils permettant de supporter une situation de conception collaborative et de capitaliser ces connaissances en vue d'une réutilisation efficace

Competency characterisation by means of work situation modelling.

International audienceNowadays companies have to face the rapid evolution of their competitive environment. In the field of design, project managers are aware of both the impact of the designers' competencies on the project performance and of the requirement for a fast development of these competencies. However, they have difficulties in updating competency reference banks and then, in correctly matching the available competencies and missions that have to be performed. This issue of competence management mainly concerns competency allocation and project team building. In research literature, numerous research works suffer from poor competence modelling. Even if some authors have linked competence with work situation, there is often a lack of documentation concerning knowledge capturing about a designer's work situation which would help managers characterise competency. In this paper, we present the architecture of a novel approach based on the traceability of design activities which aims at assisting competency characterisation through qualitative features of the work situation in which this competency is activated

Modelling framework of a traceability system of improve knowledge sharing and collaborative design.

International audienceIn collaborative design, the results of each activity imply modifications of different objects of the situation and are likely to affect the achievement of other activities. The use of collaborative tools enhances the capitalization process, especially at the stage of information collecting. Conversely, capitalized knowledge can also promote cooperation between actors regarding their situation in common. This paper develops a new modelling framework of a traceability system, based on the concept of work situation, to improve knowledge sharing and collaborative design. It aims at giving designers a collaborative tool to capture information of their work and, simultaneously, a view of the progress of their activity and of other inter-related activities

Cadre conceptuel pour un système de traçabilité en conception collaborative.

National audienceEn conception collaborative, les résultats de chaque activité entraînent des modifications sur les différents éléments de fla situation de travail et sont susceptibles de perturber l'achèvement des autres activités. L'utilisation d'outils collaboratifs favorise le processus de capitalisation surtout lors de la collecte d'informations. De même, la capitalisation des connaissances peut aussi favoriser la coopération des concepteurs dans leurs activités communes. Ce papier présente un nouveau cadre conceptuel pour un système de traçabilité, basé essentiellement sur le concept de situation, dans le dessein d'améliorer le partage des connaissances et la conception collaborative. Son but est de fournir aux concepteurs un outil collaboratif pour la capture d'informations sur leur activité et leur travail en vue d'améliorer leur pratique

A fuzzy approach for competency characterisation based on a work situation analysis.

International audienceThe purpose of this work is to give a decision support to meet requirements in competencies management. We assume that the building, the development, and the use of each competency need the concurrence of different kinds of interactions in the real work situation. The competency characteristics can be evaluated by an expert within an analysis of work situation, to get an interpretation of these interactions. In this sense, we propose a qualitative method of competency characterisation based on a formal representation of the situation. The aim of this paper is not to give all mathematical details of a fuzzy approach but rather to present how qualitative knowledge about the situation can be used to characterise associated competency

Modelling interactions to support and manage collaborative decision-making processes in design situations.

International audienceTo cope with the increasing complexity of products, New Product Development (NPD) projects require the involvement of several designers coming from various functional departments. Designers' decisions imply modifications on different objects and are likely to affect the decision-making of other designers. Two kinds of collaborative activities are strongly inter-related: technical ones that result in decisions regarding the product definition and organizational ones that concern the project organization. In this paper, we aim at developing a new conceptual framework for modelling, managing and tracking decision-making processes that are knowledge-intensive and collaborative. This framework intends to help designers to support both technical and organizational decisions. Its originality comes from the concepts of “specific role” and “action plan” that enhance the recursive modelling of activities and are valuable at different detail levels of the decisionmaking processes: project, team and individual levels. Specific decision-making models and an industrial case study illustrate the relevance of the proposed framework

Towards a knowledge structuring framework for decision making within industry 4.0 paradigm

International audienceThis article discusses the importance of data and knowledge structuring to allow their exploitation in emergent context of industry of the future. The complexity of integrating knowledge into decision support systems is particularly due to the heterogeneity of knowledge sources and the large volume of data to be analyzed. This problematic is challenging in the context of high-speed machining of aeronautical mechanical parts because of the high quality and safety constraints requested in this business area. To answer the above problem, this paper proposes a new semantic modeling framework covering both generic business knowledge and real time data. The application to the proposed semantic models for decision aid perspective within the SmartEmma project is also discussed

A Tailored Ontology Supporting Sensor Implementation for the Maintenance of Industrial Machines

International audienceThe longtime productivity of an industrial machine is improved by condition-based maintenance strategies. To do this, the integration of sensors and other cyber-physical devices is necessary in order to capture and analyze a machine's condition through its lifespan. Thus, choosing the best sensor is a critical step to ensure the efficiency of the maintenance process. Indeed, considering the variety of sensors, and their features and performance, a formal classification of a sensor's domain knowledge is crucial. This classification facilitates the search for and reuse of solutions during the design of a new maintenance service. Following a Knowledge Management methodology, the paper proposes and develops a new sensor ontology that structures the domain knowledge, covering both theoretical and experimental sensor attributes. An industrial case study is conducted to validate the proposed ontology and to demonstrate its utility as a guideline to ease the search of suitable sensors. Based on the ontology, the final solution will be implemented in a shared repository connected to legacy CAD (computer-aided design) systems. The selection of the best sensor is, firstly, obtained by the matching of application requirements and sensor specifications (that are proposed by this sensor repository). Then, it is refined from the experimentation results. The achieved solution is recorded in the sensor repository for future reuse. As a result, the time and cost of the design process of new condition-based maintenance services is reduced

PLM-based approach for collaborative design between OEM and suppliers : case study of aeronautic industry.

To achieve different assembly operations on the aircraft structure, the aeronautic OEM needs to create and manage various fixture tools. To cope with these needs, the OEM begun to adopt the supplier integration into the tooling development process. This paper presents a conceptual PLM-based approach to support new business partnership of different suppliers. The new business partnership aims to improve the role of supplier in the different tasks of design, configuration and fabrication of the tooling. The use of the PLM concepts is proposed to enhance the collaboration between OEM and the equipment's suppliers. UML models are proposed to specify the structure of the PLM solution. These models describe the relation between the aircraft assembly project, and the tooling design process
