  • Enabling safety-informed design decision making through simulation, reasoning and analysis

    Creator:
    Jensen, David Charles
    Abstract:
    While many organizations claim to "put safety first," safety is rarely considered early in the design process when system-level architectural decisions are made. Instead, system design follows an abstraction-to-detail process to first meet functional and then performance requirements. Following this process, safety assurance occurs in the later stages of design...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • Towards reliable and survivable ocean wave energy converters

    Creator:
    Brown, Adam C.
    Abstract:
    Ocean wave energy is a new and developing field of renewable energy with great potential. The energy contained in one meter of an average wave off the coast of Newport Oregon could supply dozens of homes with electricity. However, ocean waves are usually quite irregular which leads to large bursts...

  • Systematic design of biologically-inspired engineering solutions

    Creator:
    Nagel, Jacquelyn Kay
    Abstract:
    Biological organisms, phenomena and strategies, herein referred to as biological systems, provide a rich set of analogies that can be used to inspire engineering innovation. Biologically-inspired, or biomimetic, designs are publicly viewed as creative and novel solutions to human problems. Moreover, some biomimetic designs have become so commonplace that it...
