  • Risk-based design for multidisciplinary complex systems

    Creator:
    Farhangmehr, Farzaneh
    Abstract:
    The ultimate goal of large-scale design organizations are mainly to reduce costs and improve reliability and performance of systems while assessing how much risk (cost, schedule, scope) they can take and still remain competitive. To achieve this goal they need to develop tools to reach the most preferred design product...

  • Optimization Across Decomposition : A Multiagent Model of Collaboration in Decomposed System Design

    Creator:
    Hulse, Daniel E.
    Abstract:
    Complex engineered systems design is a collaborative activity. To design a system, experts from the relevant disciplines must work together to create the best overall system from their individual components. This situation is analogous to a multiagent system in which agents solve individual parts of a larger problem. Current multiagent...

  • 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...

  • 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 Computational Framework for Resilience-Informed Design

    Creator:
    Hulse, Daniel E.
    Abstract:
    It is desirable for complex engineered systems to perform missions efficiently and economically, even when these missions' complex, variable, long-term operational profiles make it likely for hazards to arise. It is thus important to design these systems to be resilient so that they will actively prevent and recover from hazards...

  • 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...

  • 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...

  • Design of Complex Engineered Systems Using Multiagent Coordination

    Creator:
    Soria Zurita, Nicolás Francisco
    Abstract:
    This thesis is the combination of two research publications working toward a unified strategy in which the design of complex engineered systems can be completed using a multiagent coordination approach. Current engineered system modeling techniques segment large complex models into multiple groups to be simulated independently. These methods restrict the...

  • 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...

  • 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....
