Ontology Building of Manufacturing Quality Knowledge for Design Decision Support

This work was funded by National Natural Science Foundation of China (No: 70472066, 70771091), the project of Bureau of Science, Technology and Industry for National Defence, China (No. Z142008A001), the NPU Foundation for Humanities, Social Science, and Management Science Development (No. RW200817), which are gratefully acknowledged.Manufacturing knowledge on product quality is a kind of typical knowledge for supporting design decisions. In order to clearly identify and understand design decisions and their knowledge needs on manufacturing quality, an ontology of design decisions and manufacturing quality knowledge is developed. The methodology and tool used for the development of the proposed ontology is firstly introduced. The design decisions are organized along with five main design phases ranging from planning and task clarification, conceptual design, embodiment design to detail design. The knowledge needs of different design decisions, especially on the manufacturing quality knowledge, are analyzed through competition questions. Then, the ontology is built in the form of a hierarchical structure through the proposed methodology and ontology editor. Based on the developed ontology, further instances of the classes in the ontology can be filled as detailed knowledge, and can be accumulated for further construction of knowledge base

XML-based knowledge management for DFM

International audienceDuring the last ten years, concurrent engineering has been largely studied and this new industrial organisation has been commonly adopted in most of huge automotive and aeronautics enterprises and in several SMEs as well. Every design phases are currently more and more narrowed and realised simultaneously during product design process. Product life cycle knowledge has now to be integrated as soon as possible during product development in order to improve the collaborative design. This paper aims at presenting an approach to manage and integrate manufacturing knowledge in design. Some first specifications are presented for the database structure using XML (eXtended Markup Language). This manufacturing knowledge is used in several contexts as teaching and scientific research on Design for Manufacture (DFM). XML language allows filtering information according to the real need of users. This need is straight linked to user’s activity and the main idea of knowledge management is then to provide the right information to this designer at the right time during his activity. The DFM activity is also briefly presented in the paper via product manufacturability analysis and synthesis method and modelling

Interoperability between Cooperative Design Modeller and a CAD System: Software Integration versus Data Exchange

International audienceThe data exchange between Computer-Aided Design (CAD) systems is a crucial issue in concurrent engineering and collaborative design. The paper presents research works and techniques dealing with the interoperability of a Cooperative Design Modeller (CoDeMo), aiming at the integration of product lifecycle knowledge, and a commercial CAD system (CATIA V5). Two kinds of approaches are implemented in the considered case of CAD interoperability for exchanging geometric data, respectively: one is based on a traditional static interface, in which STEP AP203 standard is used; the other is based on a dynamic interface, in which Application Programming Interfaces (API) of the targeted CAD system is adopted. Both approaches should enhance the communication, exchange and sharing of product data between CAD systems for improving concurrent engineering. A comparison between these two approaches is made to show their particular advantages and disadvantages. The development of a translator between the both CAD systems based on each approach has been carried out and evaluated on an assembly case

UML Based Specifications of PDM Product Structure and Workflow

International audienceThe paper deals with the use of UML approach for the specification of a PDM system. A PDM enables the management of the product data about its entire lifecycle. The main goal of the paper is to highlight the added value of in using an object-oriented approach to modelling and implementing a PDM in a business case study. The chosen object-oriented approach and the used UML diagrams for themodelling and integration of product, process, and resource data is detailed for a turboprop aircraft project

TOWARDS A DATA MODEL FOR PLM APPLICATION IN BIO-MEDICAL IMAGING

International audienceBio-Medical Imaging (BMI) is currently confronted to data issues similar to those of the manufacturing industry twenty years ago. In particular, the need for data sharing and reuse has never been so strong to foster major discoveries in neuroimaging. Some data management systems have been developed to meet the requirements of BMI large-scale research studies. However, many efforts to integrate the data provenance along a research study, from the specifications to the published results, are to be done. Product Lifecycle Management (PLM) systems are designed to comply with manufacturing industry expectations of providing the right information at the right time and in the right context. Consequently PLM systems are proposed to be relevant for the management of BMI data. From a need analysis led with the GIN research group, the BMI-LM data model is designed: it is PLM-oriented, generic (enabling the management of many types of data such as imaging, clinical, psychology or genetics), flexible (enabling users’ customisation) and it covers the whole stages of a BMI study from specifications to publication. The test implementation of the BMI-LM model into a PLM system is detailed. The preliminary feed-back of the GIN researchers is discussed in this paper: the BMI-LM data model and the PLM concepts are relevant to manage BMI data, but PLM systems interfaces are unsuitable for BMI researchers

PLM interopérable pour la conception intégrée et le travail collaboratif en aéronautique

Résumé - L’entreprise étendue devrait permettre de répondre aux objectifs bien connus de l’industrie aéronautique, à savoir réduire le temps de mise sur le marché, réduire les coûts de développement et partager les risques entre les partenaires. La réalisation d’un tel concept ne pourra passer qu’à travers des approches comme l’ingénierie collaborative, qui vise à lier les départements en charge du développement produit entre les différents partenaires du projet. Dans ce cadre, le succès des plateformes dites « d’ingénierie collaborative » est devenu une des préoccupations majeures des principaux acteurs industriels de l’aérospatial. En même temps, les aéronefs se complexifient indéniablement et sont même déjà hautement pluridisciplinaires. C’est pourquoi, la collaboration dans les projets de développement produit se doit de supporter la conception intégrée. Après avoir fait une brève relecture de la littérature sur ces différents concepts, ce papier présentera les spécifications d’une plateforme d’ingénierie collaborative à destination de l’industrie aéronautique : La plateforme SEINE (Standard pour l’Entreprise Innovante Numérique Etendue). Puis nous verrons comment une telle plateforme pourrait être enrichie en matière de conception intégrée. Abstract - Well known challenges in Aeronautic industry, namely reduced time to market, lower development costs and shared risks between partners, could be reached thanks to the innovative design methods supported by PLM technologies. Reaching such objective will be allowed through methods like integrated design or collaborative engineering enabling close exchanges between the project partners. In fact, the success of PLM platforms in supporting such methods is becoming one of the major stakes in the global networking organization. At the same time, aircrafts are obviously systems integrating multidisciplinary technologies and companies are highly multiple expertises. This paper proposes a survey on integrated design methods, PLM technologies and related subjects. It also presents the specification and the development of a collaborative design platform, as part of SEINE project (Standard pour l’Entreprise Innovante Etendue), aiming to improve collaboration in French aeronautics supply chain. Finally, this paper proposes how to include multiple expertise and integrated design in this “platform supporting” partners collaboration
