    Service Knowledge Capture and Reuse

    Get PDF
    The keynote will start with the need for service knowledge capture and reuse for industrial product-service systems. A novel approach to capture the service damage knowledge about individual component will be presented with experimental results. The technique uses active thermography and image processing approaches for the assessment. The paper will also give an overview of other non-destructive inspection techniques for service damage assessment. A robotic system will be described to automate the damage image capture. The keynote will then propose ways to reuse the knowledge to predict remaining life of the component and feedback to design and manufacturing

    The influencing mechanism of manufacturing scene change on process domain knowledge reuse

    It is necessary for a enterprise to reuse outside process domain knowledge to develop intelligent manufacturing technology. The key factors influencing knowledge reuse in digital manufacturing scene are manufacturing activities and PPR (Products, Processes and Resources) related to knowledge modeling, enterprise and integrated systems related to knowledge utilizing. How these factors influence knowledge modeling and utilizing is analyzed. Process domain knowledge reuse across the enterprises consists of knowledge reconfiguration and integrated application with CAx systems. The module-based knowledge model and loosely-coupled integration application of process domain knowledge are proposed. The aircraft sheet metal process domain knowledge reuse is taken as an example, and it shows that the knowledge reuse process can be made flexible and rapid

    Software Reuse in Agile Development Organizations - A Conceptual Management Tool

    Get PDF
    The reuse of knowledge is considered a major factor for increasing productivity and quality. In the software industry knowledge is embodied in software assets such as code components, functional designs and test cases. This kind of knowledge reuse is also referred to as software reuse. Although the benefits can be substantial, software reuse has never reached its full potential. Organizations are not aware of the different levels of reuse or do not know how to address reuse issues. This paper proposes a conceptual management tool for supporting software reuse. Furthermore the paper presents the findings of the application of the management tool in an agile development organization

    Design reuse research : a computational perspective

    Get PDF
    This paper gives an overview of some computer based systems that focus on supporting engineering design reuse. Design reuse is considered here to reflect the utilisation of any knowledge gained from a design activity and not just past designs of artefacts. A design reuse process model, containing three main processes and six knowledge components, is used as a basis to identify the main areas of contribution from the systems. From this it can be concluded that while reuse libraries and design by reuse has received most attention, design for reuse, domain exploration and five of the other knowledge components lack research effort

    Knowledge Reuse for Customization: Metamodels in an Open Design Community for 3d Printing

    Full text link
    Theories of knowledge reuse posit two distinct processes: reuse for replication and reuse for innovation. We identify another distinct process, reuse for customization. Reuse for customization is a process in which designers manipulate the parameters of metamodels to produce models that fulfill their personal needs. We test hypotheses about reuse for customization in Thingiverse, a community of designers that shares files for three-dimensional printing. 3D metamodels are reused more often than the 3D models they generate. The reuse of metamodels is amplified when the metamodels are created by designers with greater community experience. Metamodels make the community's design knowledge available for reuse for customization-or further extension of the metamodels, a kind of reuse for innovation

    Supporting 'design for reuse' with modular design

    Get PDF
    Engineering design reuse refers to the utilization of any knowledge gained from the design activity to support future design. As such, engineering design reuse approaches are concerned with the support, exploration, and enhancement of design knowledge prior, during, and after a design activity. Modular design is a product structuring principle whereby products are developed with distinct modules for rapid product development, efficient upgrades, and possible reuse (of the physical modules). The benefits of modular design center on a greater capacity for structuring component parts to better manage the relation between market requirements and the designed product. This study explores the capabilities of modular design principles to provide improved support for the engineering design reuse concept. The correlations between modular design and 'reuse' are highlighted, with the aim of identifying its potential to aid the little-supported process of design for reuse. In fulfilment of this objective the authors not only identify the requirements of design for reuse, but also propose how modular design principles can be extended to support design for reuse

    Knowledge Reuse - Insights from Software Reuse

    Get PDF
    We are moving towards an economy where competitive advantage will be determined by knowledge. In their knowledge management strategies, many companies currently aim to encourage knowledge reuse. In this paper, we examine insights drawn from a related field — software reuse — for their relevance to the emerging field of knowledge reuse. We first examine different types of reuse: components, patterns, frameworks and general principles. We then evaluate different kinds of reuse activities. Finally, we discuss lessons from cultural issues in software reuse

    An analysis of design reuse benefits

    Get PDF
    Although the concept of design reuse is accepted as a valid approach to design, little attempt has been made to formalise the elements that constitutes design reuse. The few approaches formalising design reuse, e.g. 'Concept Reuse Approach for Engineering Design Problem Solving', tend to be prescriptive, detailing procedures and functions that have to be carried out in order to reuse designs. Such procedural methods fail to identify the underlying processes and knowledge resources of design reuse and tend to relate to an approach or method of tackling reuse rather than reuse itself. It would seem that the only current model encompassing design reuse is 'The Design Reuse Process Model'. The elements of this reuse process model have been used as a basis upon which to identify and analyse the benefits of design reuse when considering key metrics relating to competitive product development,that is time, cost, quality and performance
