UML Based Specifications of PDM Product Structure and Workflow

The 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

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

Towards Assessment of information system agility

International audienceCurrently, the information systems agility and the satisfaction of the dynamic environment requirements is essential challenges for companies. The purpose of this paper is to represent the existing approaches for achieving agility in software development as well as in production system. The objective is to identify the relevant metrics for evaluating information system agility. Then, we propose an analysis model that contains these agile metrics, to observe their combination in information system

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

Learning from the lifecycle:The capabilities and limitations of current product lifecycle practice and systems

Design teams within the High Value Low Volume (HVLV) industry are facing ever-increasing challenges in developing new products. This has been largely due to the paradigm shift towards Product Service Systems, the growing importance of demonstrating Corporate Social Responsibility and stricter environmental legislation. With the variant nature of the design process within the HVLV industry and the longevity of the product life-cycles, it is recognised that learning from previous products is essential for new product innovation and development. The ability to do this depends upon the company’s product lifecycle practice and systems, and its inherent capability/limitations. To explore these issues, this paper maps typical data and information flow and the Information Systems involved, onto a generalised product lifecycle for HVLV. The map is generated from an extensive literature review and is used to critically appraise and reflect upon current product data lifecycle practice. In particular, its capability to provide design teams in the HVLV industries with sufficient data and information throughout the lifecycle phases of existing products to inform variant product design is considered

A modular product structure based methodology for seamless information flow in PLM system implementation

Product development process deals with large amount of information generated from market survey, concept design, manufacture, test, limited production, production, service, and obsoleting. The information should be stored systematically so that it is easily traceable and reusable for future product development. This paper presents a methodology for seamless product information flow between the three main enterprise information systems such as Computer Aided Design and Manufacturing (CAD/CAM), Product Data/Lifecycle Management (PDM/PLM) and Enterprise Resource Planning (ERP) used in the process of innovative product development while implementing PLM. PLM implementation deals with various existing product data and information generated over years both from CAD and ERP systems. Data integration is very challenging in multi-national engineering companies and has important impact on future decisions while creating new processes. The aim is to define a modular product structure that can be used to connect the product information throughout the life cycle that can be reused effectively and efficiently for future similar products
