  • A framework to model reliability and failures in complex systems during the early engineering design process

    Creator:
    O'Halloran, Bryan M.
    Abstract:
    An open area of research in complex systems is to move reliability and failure assessments earlier in the engineering design process. When compared to later design, early decisions are cost effective and have a large impact on the system. Standard methods are limited by the availability of data and often...

  • Evaluating complex engineered systems using complex network representations

    Creator:
    Haley, Brandon M.
    Abstract:
    This thesis is the combination of two research publications working toward a unified strategy in which to represent complex engineered systems as complex networks. Current engineered system modeling techniques segment large complex models into multiple groups to be simulated independently. These methods restrict the evaluations of such complex systems as...

  • Exploring experimental test stand design and operation within a system reliability research methodology

    Creator:
    Koopmans, Michael, 1986-
    Abstract:
    In cases where complex systems routinely experience extreme operating conditions, preventative maintenance is often employed to guard against system failure. Yet, with accessible real-time data and the standard practice becoming prohibitively expensive, the test stand can serve as a vital contributor to the development of system health and reliability estimations....

  • Modeling innovativeness in consumer products with the influence of environmental sustainability

    Creator:
    Gilchrist, Brady
    Abstract:
    This thesis is the result of two research publications, which together form a framework for the evaluation of product innovativeness with potential future applications to early design. Innovation is a challenging concept to quantify. Experts seemingly have a grasp of what innovation is when they see it, however this evaluation...

  • The Function-Human Error Design Method (FHEDM)

    Creator:
    Soria Zurita, Nicolás F.
    Abstract:
    This research presents a methodology to identify and analyze human-system interactions, and their potential failure modes using a functional decomposition approach during the early system design stage. The fundamental research contribution of this work is the development of a framework to identify associations between physical user-product interactions, generic human errors...

  • Towards a guided framework for innovative engineering through the generation and evaluation stages of concept design

    Creator:
    Oman, Sarah Kay
    Abstract:
    This work proposes a framework of concept generation and evaluation that takes into consideration the benefit of creativity and innovation in current market trends. By educating engineers in how to increase creativity in concept design and assess it quantitatively, the next generation of designers will be a step ahead of...

  • The Structural Characteristics of Robustness in Large-Scale Complex Engineered Systems

    Creator:
    Walsh, Hannah S.
    Abstract:
    Modern engineered systems are increasingly integrated into society, decentralized, and interconnected. However, scale and complexity create unique challenges in system design, such as emergent behavior and unintended consequences. This work investigates the structural characteristics of robustness in complex engineered systems by identifying patterns of under-recognized vulnerabilities at various levels of...

  • A Framework to Evaluate the Risk of Human- and Component-related Vulnerability Interactions

    Creator:
    Irshad, Lukman
    Abstract:
    Most accidents and malfunctions in complex engineered systems are attributed to human error. However, a closer inspection would reveal that such mishaps often emerge as a result of poor design and human- and component-related vulnerabilities acting together. To fully understand and mitigate potential risks, the effects of such interactions between...

  • A risk-informed decision making framework accounting for early-phase conceptual design of complex systems

    Creator:
    Van Bossuyt, Douglas L.
    Abstract:
    A gap exists in the methods used in industry and available in academia that prevents customers and engineers from having a voice when considering engineering risk appetite in the dynamic shaping of early-phase conceptual design trade study outcomes. Current methods used in Collaborative Design Centers either collect risk information after...

  • A framework for assessing and improving the resilience of complex engineered systems during the early design process

    Creator:
    Mehrpouyan, Hoda
    Abstract:
    As modern systems continue to increase in size and complexity, they pose significant safety and risk management challenges. System engineers and much of the government research efforts are focused on understanding the attributes and characteristics that emerge from the interactions of components and subsystems. As a result, the objective of...
