  • 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...

  • 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...

  • Integrated Evaluation of Drinking Water Purification: A Mixed-Method Laboratory and Field Assessment of a Biomass-Powered Water Treatment Technology

    Creator:
    Burleson, Grace Ellen
    Abstract:
    The global water crisis is defined as one of the major threats facing humankind over the next decade with over 1 in 10 people lacking access to clean drinking water worldwide. An estimated 1.2 million people pasteurize their drinking water by using boiling as an indicator. Pasteurization is the process...

  • How personality affects creativity in concept ideation

    Creator:
    Berthelsdorf, Friederich A.
    Abstract:
    This thesis uses the manuscript option, and consists of a previously-published paper and a paper that has been accepted for publication. Manuscript One details an independent confirmatory study to Choo et al. (2014), which demonstrated that correlations exist between personality type and the outcome of concept ideation methods. This is...

  • Ontologies to Support Repeatable and Valid Customer Requirements Generation

    Creator:
    Lemke, Mark T.
    Abstract:
    Due to the growing complexity, sophistication, and interconnectedness of present day engineered products and services, the use of ontologies in engineering design is becoming more widespread. An ontology provides a standardized way of describing concepts in a domain of interest and the relationships between these concepts to better understand the...

  • 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...

  • Reverse engineering, modeling, and redesign of a vibratory conveyor

    Creator:
    Foglesong, Timothy J.
    Abstract:
    Some successful products are still developed and produced without the benefit of modern design techniques. One such product is a vibratory conveyor that has been developed largely through prototype iteration. The manufacturer has collaborated with Oregon State University to introduce model-based design into the development process. This research details a...

  • 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...

  • 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...

  • Fashioning queer bodies : intersections of dress, identity, and anxiety in the queer women's community

    Creator:
    Reddy-Best, Kelly
    Abstract:
    The purpose of this study was to explore the relationship of dress and queer women and how their sexual identity influences their appearance management behaviors. I answered the following research questions: (1) How is gender identity constructed and negotiated in different spaces for queer? (2) Does sexual identity influence dress...
