    The thesis presents a ship hull form specific reverse engineering and CAD integration framework. The reverse engineering part proposes three alternative suitable reconstruction approaches namely curves network, direct surface fitting, and triangulated surface reconstruction. The CAD integration part includes surface healing, region identification, and domain preparation strategies which used to adapt the CAD model to downstream application requirements. In general, the developed framework bridges a point cloud and a CAD model obtained from IGES and STL file into downstream applications

    Strategies to Succeed in an Increasingly Technology-Based Environment: A Study of the Automotive Industry

    This dissertation investigates how firms embedded in an increasingly technology-based industry change their vertical integration and product development strategies in order to remain competitive and increase value capture. The first essay is a theoretical development integrating concepts of industry structure, organizational governance form and innovation in order to disentangle past research’s disagreements and guide future studies. Firms are seen as proactive actors that also have their decisions strongly shaped by structural (architectural) factors. The second essay focus on analyzing how module suppliers achieve a sustained competitive advantage by increasing their focus on modular products and innovations as well as managing their vertically related operations. Results from the global automotive industry reveal that suppliers are capable of capturing more value from modules when investing in modular innovations, integrating manufacturing operations via M&As and strengthening downstream relationships through strategic alliances. Lastly, the third essay investigates the great complexities involved in the manufacture of automobiles. By acknowledging the important strategic implications of managing product failures to the overall performance and reputation of organizations, this essay attempts to fill a gap in the literature by investigating how increased product, process and supplier changes affect product failure rates, and how firms manage product redesigns and learning from past product failures to increase quality reputation. Results indicates that in complex product industries such as automotive, firms find it very difficult to increase product changes without incurring also in more product failures. The results also highlight the importance of strong supplier involvement and integration as a means to reduce product failure rates. This study also demonstrates that quality reputation is better assessed by consumers when manufacturers invest more in model redesigns. Yet, it shows that experience with voluntary recalls helps firms to learn how to improve their new products and increase quality reputation

    Information technology for competitive advantage within logistics and supply chains: a review

    Get PDF
    This paper offers a systematic review of the literature on the use of information technology (IT) in logistics and supply chain management to achieve competitive advantage. While IT has revolutionized traditional logistics and supply chains to achieve numerous benefits such as increased efficiency and responsiveness, it is not still clear to what extend IT has contributed to competitive advantage within logistics and supply chains. This paper contributes to this debate by: (i) reporting the literature on the role of IT in achieving competitive advantage within logistics and supply chains based on the linkages between ‘adaptation’, ‘alignment’, and ‘agility’, (triple A’s) (Lee, 2004), and (ii) discussing managerial implications and identifying future research directions

    Systems design analysis applied to launch vehicle configuration

    Get PDF
    As emphasis shifts from optimum-performance aerospace systems to least lift-cycle costs, systems designs must seek, adapt, and innovate cost improvement techniques in design through operations. The systems design process of concept, definition, and design was assessed for the types and flow of total quality management techniques that may be applicable in a launch vehicle systems design analysis. Techniques discussed are task ordering, quality leverage, concurrent engineering, Pareto's principle, robustness, quality function deployment, criteria, and others. These cost oriented techniques are as applicable to aerospace systems design analysis as to any large commercial system

    Housing supply chain model for innovation: research report

    Get PDF
    The aim of this research is to undertake a case study analysis of successful delivery of an innovation to the Australian housing construction industry. This study is conducted on the “innovator group”; that is, the group that created the idea of an innovation for the housing sector and then were intimately involved in creation, development and diffusion. It is apparent that there were key players involved in this process which are representative of various organisations along the supply chain – designer, developer, subcontractor and supplier. Much rhetoric states that integration of the supply chain actors will solve construction problems, however, in reality we know little beyond this in the Australian context as there has been little research conducted previously. This study will examine in detail the process undertaken by this particular group to deliver an innovation to the housing sector which required an integrated construction supply chain model. This report was published by the Australian Housing Supply Chain Alliance and written by Professor Kerry London, School of Property, Construction and Project Management, RMIT University with Research Fellow, Jessica Siva

    Integrating scientific and local knowledge to inform risk-based management approaches for climate adaptation

    Get PDF
    AbstractRisk-based management approaches to climate adaptation depend on the assessment of potential threats, and their causes, vulnerabilities, and impacts. The refinement of these approaches relies heavily on detailed local knowledge of places and priorities, such as infrastructure, governance structures, and socio-economic conditions, as well as scientific understanding of climate projections and trends. Developing processes that integrate local and scientific knowledge will enhance the value of risk-based management approaches, facilitate group learning and planning processes, and support the capacity of communities to prepare for change. This study uses the Vulnerability, Consequences, and Adaptation Planning Scenarios (VCAPS) process, a form of analytic-deliberative dialogue, and the conceptual frameworks of hazard management and climate vulnerability, to integrate scientific and local knowledge. We worked with local government staff in an urbanized barrier island community (Sullivan’s Island, South Carolina) to consider climate risks, impacts, and adaptation challenges associated with sea level rise and wastewater and stormwater management. The findings discuss how the process increases understanding of town officials’ views of risks and climate change impacts to barrier islands, the management actions being considered to address of the multiple impacts of concern, and the local tradeoffs and challenges in adaptation planning. We also comment on group learning and specific adaptation tasks, strategies, and needs identified
