Integrated product relationships management : a model to enable concurrent product design and assembly sequence planning

The paper describes a novel approach to product relationships management in the context of concurrent engineering and product lifecycle management (PLM). Current industrial practices in product data management and manufacturing process management systems require better efficiency, flexibility, and sensitivity in managing product information at various levels of abstraction throughout its lifecycle. The aim of the proposed work is to manage vital yet complex and inherent product relationship information to enable concurrent product design and assembly sequence planning. Indeed, the definition of the product with its assembly sequence requires the management and the understanding of the numerous product relationships, ensuring consistency between the product and its components. This main objective stresses the relational design paradigm by focusing on product relationships along its lifecycle. This paper gives the detailed description of the background and models which highlight the need for a more efficient PLM approach. The proposed theoretical approach is then described in detail. A separate paper will focus on the implementation of the proposed approach in a PLM-based application, and an in-depth case study to evaluate the implementation of the novel approach will also be given

Multi-scale and multi-representation CAD models reconciliation for knowledge synthesis

Over the last decades, concurrent engineering and design for X approaches have introduced knowledgebased decision supports, analysis methods and feature-based modelling techniques to deliver designed solutions ready for specific lifecycle purposes. However, to cover the emerging knowledge synthesis issue in engineering design, the underlying 3D representations need to be better understood and chained. This paper aims at developing original multi-representation and multi-scale CAD models to integrate properly knowledge in their most suitable form. Reconciliation mechanisms can be set up to validate semantic continuity of the geometric models and to justify the knowledge structuring the design solutions space

Multiple viewpoint modelling framework enabling integrated product-process design

Nowadays, companies have to cope with numerous constraints at organisational and technical levels in order to improve their competitiveness edges such as productivity, efficiency, and flexibility. Integrated product-process design becomes more and more complex to manage because of increasingly customized products related to various stakeholders and concerns geographically distributed. It is still represents a huge challenge, especially in the early phases of product development process. In such a context, the management of information within integrated product-process design highlights needs in a consistent engineering model that enables product lifecycle management (PLM) integration. The paper presents a novel multiple viewpoint framework called multiple viewpoint assembly oriented, considering product design and assembly process domains in the broader context of concurrent engineering and PLM. The proposed framework describes the consistency, the propagation of information change, and mechanisms of views generation among the product lifecycle stages in order to support assembly oriented design philosophy. A new modelling language called System Modeling Language is used to describe the proposed model from a systems engineering point of view. The implementation of the model in a Web-service called PEGASUS as an application for PLM systems is describe

A spatiotemporal information management framework for product design and assembly process planning reconciliation

This paper introduces an innovative framework for product design and assembly process planning reconciliation. Nowadays, both product lifecycle phases are quasi concurrently performed in industry and this configuration has led to competitive gains in efficiency and flexibility by improving designers’ awareness and product quality. Despite these efforts, some limitations/barriers are still encountered regarding the lack of dynamical representation, information consistency and information flow continuity. It is due to the inherent nature of the information created and managed in both phases and the lack of interoperability between the related information systems. Product design and assembly process planning phases actually generate heterogeneous information, since the first one describes all information related to ‘‘what to be delivered’’ and the latter rationalises all information with regards to ‘‘how to be assembled’’. In other words, the integration of assembly planning issue in product design requires reconciliation means with appropriate relationships of the architectural product definition in space with its assembly sequence in terms of time. Therefore, the main objective is to provide a spatiotemporal information management framework based on a strong semantic and logical foundation in product lifecycle management (PLM) systems, increasing therefore actors’ awareness, flexibility and efficiency with a better abstraction of the physical reality and appropriate information management procedures. A case study is presented to illustrate the relevance of the proposed framework and its hub-based implementation within PLM systems

An assembly oriented design framework for product structure engineering and assembly sequence planning

The paper describes a novel framework for an assembly-oriented design (AOD) approach as a new functional product lifecycle management (PLM) strategy, by considering product design and assembly sequence planning phases concurrently. Integration issues of product life cycle into the product development process have received much attention over the last two decades, especially at the detailed design stage. The main objective of the research is to define assembly sequence into preliminary design stages by introducing and applying assembly process knowledge in order to provide an assembly context knowledge to support life-oriented product development process, particularly for product structuring. The proposed framework highlights a novel algorithm based on a mathematical model integrating boundary conditions related to DFA rules, engineering decisions for assembly sequence and the product structure definition. This framework has been implemented in a new system called PEGASUS considered as an AOD module for a PLM system. A case study of applying the framework to a catalytic-converter and diesel particulate filter sub-system, belonging to an exhaust system from an industrial automotive supplier, is introduced to illustrate the efficiency of the proposed AOD methodology

Conception intégrée et gestion d'informations techniques: application à l'ingénierie du produit et de sa séquence d'assemblage

In today's competitive market, companies from the automotive and aeronautic industries are required to effectively enable concurrent engineering (CE) and product lifecycle management (PLM) strategies in order to maintain their business drivers and competitiveness edges - such as productivity, efficiency, and flexibility - especially at the beginning of product lifecycle process. Within this context, a particular industrial requirement is needed for the integration of lifecycle considerations at different life aspects from the early product development process with the related support of data-information-knowledge management systems. It is therefore important to provide a decision making support as soon as possible, in order to produce a better, assembly friendly, product. This research is in the fields of integrated design and information management with a particular focus on product structure engineering and assembly sequence planning. The latter has been developed by setting up a multi-view model entitled MUlti-View Assembly Oriented (MUVOA) to map concepts in the area of product and assembly process for the definition, the propagation, and the traceability of product and process information along the product life cycle. A set of interrelated views (functional, behavioral, structural, geometric, technological and contextual) has been defined according to profiles (role, concern, concepts, business process, etc.) of the stakeholders involved in assembly oriented design issues, namely the product architect, the assembly planner, the designer and the process expert. Based on the MUVOA model, a framework called Proactive ASsembly Oriented DEsign (PASODE) has been proposed in order to define an optimal assembly sequence in the early product development process, and used to define a skeleton-based assembly context in product geometric view. Thus, the proposed PASODE framework includes three approaches, which are: the approach based on the ASDA algorithm (Assembly Sequence Definition Algorithm), dedicated to the definition/planning of assembly sequences in the preliminary product development process; the SKL-ACD approach (SKeLeton-based Assembly Context Definition), dedicated to the definition of a skeleton-based assembly context; and the PRM approach (Product Relationships Management), for the management of product relationships at various abstraction levels in the context of PLM. The proposed MUVOA model and PASODE framework have been implemented in a new application called PEGASUS at the interface of PLM systems such as PDM (Product Data Management), MPM (Manufacturing Process Management) and CAD (Computer Aided Design) systems. The computer implementation is based on the Model View – ViewModel method and C# programming language that enables us to achieve three industrial applications to demonstrate the three proposed approaches. Among the use cases, we have introduced a case study of a Catalytic converters and Diesel Particulate Filter in collaboration with Faurecia ECT from automotive industry, the design of fuselage section of an aircraft in collaboration with EADS IW from aeronautic industry, and the design of a pneumatic drill for the enterprise MABI.Dans le contexte concurrentiel actuel, les entreprises issues des secteurs automobile et aéronautique doivent impérativement mettre en place, de manière efficace, des stratégies d'ingénierie intégrée et de gestion de cycle de vie des produits, ceci afin de maintenir leurs facteurs de compétitivité, tels que la productivité, l'efficacité et la flexibilité, en particulier en phase de début de cycle de vie des produits (développement et industrialisation). Dans ce contexte, une condition industrielle nécessaire est requit pour l'intégration des contraintes liées aux différentes phases du cycle de vie du produit au sein du processus de développement avec le support de systèmes permettant la gestion des données-informations-connaissances. Dès lors, il est important d'apporter, le plus tôt possible, une aide à la décision en ingénierie, afin de fournir un produit se prêtant aux problématiques liées aux phases de son cycle de vie. Ce travail de thèse s'inscrit dans les domaines de la conception intégrée et de la gestion des informations techniques, plus particulièrement centrée sur le produit et sa séquence d'assemblage. Celui-ci a consisté à la mise en place d'un modèle multi-vues baptisé MUlti-Vues Orienté Assemblage (MUVOA) visant à cartographier les concepts dans les domaines du produit et du processus d'assemblage pour la définition, la propagation et la traçabilité des informations du couple produit-process. Un ensemble de vues interdépendantes (fonctionnelle, comportementale, structurelle, géométrique, technologique et contextuelle) a été défini en fonction des profils (rôle, préoccupation, termes métier, processus métier, etc.) des acteurs métier impliqués dans les questions de conception orientée assemblage, à savoir l'architecte produit, le gammiste, le concepteur et l'expert process. Sur la base de ce modèle MUVOA, un cadre méthodologique baptisé Proactive ASsembly Oriented DEsign (PASODE) a été proposé, ceci afin de définir une séquence d'assemblage optimale dans les phases préliminaires du processus de développement, et de l'utiliser pour définir un contexte d'assemblage à base de squelettes dans la vue géométrique produit. De ce fait, le cadre méthodologique PASODE proposé regroupe trois approches, telles que : l'approche basée sur l'algorithme ASDA (Assembly Sequence Definition Algorithm) dédiée à la définition/planification de séquences d'assemblage en phases préliminaires du processus de développement des produits, l'approche SKL-ACD (SKeLeton-based Assembly Context Definition) dédiée la définition d'un contexte d'assemblage à base de squelettes géométriques, et l'approche PRM (Product Relationships Management) dédiée à la gestion des relations du produit à différents niveaux d'abstraction en contexte PLM. Le modèle MUVOA ainsi que le cadre méthodologique PASODE ont été mis œuvre dans un outil informatique appelé PEGASUS, situé à l'interface des systèmes PLM (Product Lifecycle Management) associés à la gestion des informations techniques du couple produit-process, tels que les systèmes PDM (Product Data Management), MPM (Manufacturing Process Management) et CAO (Conception Assistée par Ordinateur). Cette implémentation informatique, basée sur la méthode Modèle Vue - VueModèle et le langage C#, nous a permis de réaliser trois expérimentations industrielles, afin d'illustrer et de valider les trois approches du cadre méthodologique. Parmi les cas d'applications, nous avons introduit un cas de conception d'un combiné Catalyseur – Filtre à Particules en collaboration avec l'entreprise Faurecia Technologies de Contrôle des Emissions (ECT), la conception de la partie structurelle d'un avion de type A320 en collaboration avec l'entreprise EADS Innovation Works, et un dernier cas avec l'entreprise MABI sur la conception d'un marteau burineur pneumatique
