    Design Rework Prediction in Concurrent Design Environment: Current Trends and Future Research Directions
    (Cranfield University Press, 2009-03-31) Arundachawat, Panumas; Roy, Rajkumar; Al-Ashaab, Ahmed; Shehab, Essam; Rajkumar Roy; Essam Shehab
    This paper aims to present state-of-the-art and formulate future research areas on design rework in concurrent design environment. Related literatures are analysed to extract the key factors which impact design rework. Design rework occurs due to changes from upstream design activities and/or by feedbacks from downstream design activities. Design rework is considered as negative iteration; therefore, value in design activities will be increased if design rework is reduced. Set-based concurrent engineering is proposed as an alternative design approach to mitigate design rework risk, however, duplication effort for designing set of artefacts are still needed to consider before selecting set-based concurrent engineering in design activities.

    Modelling the Product Development performance of Colombian Companies
    (Cranfield University Press, 2009-03-31) Herrera-Hernandez, M. C.; Luna, C.; Prada, L.; Berdugo, C.; Al-Ashaab, Ahmed; Rajkumar Roy; Essam Shehab
    This paper presents the general model of the Product Development Process (PDP) in the Metal mechanics Industry in Barranquilla-Colombia, since this sector contributes significantly to the productivity of this industrial city. This case study counted on a five-company sample. The main goal was to model the current conditions of the PDP according to the Concurrent Engineering philosophy. The companies were selected according to their productive profile, in order to contrast differences regarding the structure of their productive processes, conformation of multidisciplinary teams, integration of different areas, customers and suppliers to the PDP; human resources, information, technology and marketing constraints.

    Set-Based Concurrent Engineering Model for Automotive Electronic/Software Systems Development
    (Cranfield University Press, 2009-03-31) Al-Ashaab, Ahmed; Howell, S.; Usowicz, K.; Hernando Anta, P.; Gorka, A.; Rajkumar Roy; Essam Shehab
    This paper is presenting a proposal of a novel approach to automotive electronic/software systems development. It is based on the combination of Set-Based Concurrent Engineering, a Toyota approach to product development, with the standard V-Model of software development. Automotive industry currently faces the problem of growing complexity of electronic/software systems. This issue is especially visible at the level of integration of these systems which is difficult and error-prone. The presented conceptual proposal is to establish better processes that could handle the electronic/software systems design and development in a more integrated and consistent manner.
