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

    Get PDF
    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

    Project-based collaborative engineering learning to develop Industry 4.0 skills within a PLM framework

    Training and learning methods for engineering students, in the disciplines of product design and manufacturing, are becoming more difficult and complex since they have to integrate theoretical technical knowledge, skills in computer-aided applications (CAx) and skills in collaborative work practices. Product Lifecycle Management (PLM) tools support structured collaborative practices and CAx supports engineering content creation. Both types of software applications are key in the Industry 4.0 development. They also evolve over time, incorporate new functionalities, and change their graphical user interface (GUI), adding complexity to the learning process. Traditionally, engineering education addresses the learning of CAx and PLM tools separately, hindering a holistic learning experience to the students. This communication presents a structured integrated vision of these tools and their learning. Project-Based Learning (PBL) is proposed as a learning approach suitable to provide a learning experience that facilitates the development of Industry 4.0 skills and competences

    Enabled virtual and collaborative engineering coupling PLm system to a product data kernel

     Nowadays, the use of digital modelling through multiple CAx systems becomes more and more unquestionable. It allows many benefits (3D, automations, simulations, etc.) in spite of the fact that those different systems are individually used and are relatively isolated (i.e. not interoperable) during the product design process. Then more enhancement of product development might be possible if the whole design expertises (and IT applications), could collaborate dynamically (i.e. interoperate) in a complete virtual and collaborative engineering platform. For instance, product definition could be therefore seen as the synthesis of multidisciplinary information defined and assessed with respect to both collaborative activity and individual domain of expertise. At the same time, PDM/PLM systems are developed in most of cases as product data vault (product data referential of a company with internal PDM or projects collaborative referential with collaborative engineering platform). Nevertheless, current PLM are not able to manage more than only files (and not data breakdown) and then are not yet efficient for CAx systems interoperability. The paper aims at giving some first concepts and software demonstrators in order to tackle the problem of interoperability in virtual engineering design. The proposal is based on the PPO data kernel: a dynamic data structure able to integrate and merge multidisciplinary product data breakdown and to exchange them with other CAx applications. Then the current PDM/PLM systems will be defined as one of the CAx systems which interoperate with the kernel to benefit of both PLM and CAx potential functionalities. A business case will be studied between the PPO product data kernel and the Windchill (from PTC vendor) PLM system. Some recommendations for future work are then discussed to present what could be a generic interoperable software platform.

    [EN] Universities are one of the fundamental actors to guarantee the dissemination of knowledge and the development of competences related to the Industry of the Future (IoF) or Industry 4.0. Computer Aided (CAX) and Product Lifecycle Management (PLM) technologies are key part in the IoF. With this aim, it was launch a project focused on Manufacturing and partially funded by La Fondation Dassault Systèmes. This communication presents a review on CAX-PLM training, four initiatives already in place in universities participating in the project, the project scope, the approach to integrate with the industrial context, the working method to consider different competence profiles and the development framework.The authors express their gratitude to the other project colleagues and to La Fondation Dassault Systèmes for its funding support.Ríos, J.; Mas, F.; Marcos, M.; Vila, C.; Ugarte, D.; Chevrot, T.

    A collaborative platform for integrating and optimising Computational Fluid Dynamics analysis requests

    Get PDF
    A Virtual Integration Platform (VIP) is described which provides support for the integration of Computer-Aided Design (CAD) and Computational Fluid Dynamics (CFD) analysis tools into an environment that supports the use of these tools in a distributed collaborative manner. The VIP has evolved through previous EU research conducted within the VRShips-ROPAX 2000 (VRShips) project and the current version discussed here was developed predominantly within the VIRTUE project but also within the SAFEDOR project. The VIP is described with respect to the support it provides to designers and analysts in coordinating and optimising CFD analysis requests. Two case studies are provided that illustrate the application of the VIP within HSVA: the use of a panel code for the evaluation of geometry variations in order to improve propeller efficiency; and, the use of a dedicated maritime RANS code (FreSCo) to improve the wake distribution for the VIRTUE tanker. A discussion is included detailing the background, application and results from the use of the VIP within these two case studies as well as how the platform was of benefit during the development and a consideration of how it can benefit HSVA in the future
