  • 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...

  • Equipment replacement prioritization measures : simulation and testing for a vehicle fleet

    Creator:
    Kriett, Phillip Oliver
    Abstract:
    Oregon Department of Transportation (ODOT) Fleet Services manages a fleet that in 2008 included approximately 5,000 pieces of active equipment worth $340–$390 million. Every biennium, a fixed budget is available to replace a certain amount of this equipment. This research evaluated various measures for establishing equipment replacement priorities. A model...

  • Optimization & Qualification of a Liquid Engine Launch Vehicle Design Using 6DoF Simulations

    Creator:
    Rose, Trevor J.
    Abstract:
    In this work, I developed a six degree of freedom flight simulator specific to liquid engine launch vehicles. This flight simulator improves upon available software by accounting for liquid engine specific phenomena such as tank pressurization, liquid engine performance, and center of gravity modeling. Additionally, I implemented methods for optimization...

  • An economic and environmental assessment model for microchannel device manufacturing

    Creator:
    Gao, Qi
    Abstract:
    A key application of microchannel process technology (MPT) is its implementation in heat exchanger devices, since a larger surface contact area can be realized than in conventional approaches, thus achieving high heat transfer efficiency. To justify high volume production of configurations validated as prototypes, and to select from among the...

  • Multi-Robot Coordination : Applications in Orchard Bin Management and Informative Path Planning

    Creator:
    Zhang, Yawei
    Abstract:
    Efficient coordination is desired for multi-robot systems in many scenarios. In this research, we first provide a multi-robot system to help human workers during tree fruit harvest. We present an auction-based method to coordinate a team of self-propelled bin carriers to retrieve fruit bins. Second, we propose a more general...

  • Multi-objective Optimization for Equitable Post-Disaster Relief Supply Distribution

    Creator:
    Subramaniam, Purnima
    Abstract:
    Humanitarian logistics in the post-disaster phase of an earthquake requires detailed planning about the relief distribution network including assigning available distribution centers (DCs) to the affected areas, distribution of the relief commodities demanded by the affected population, and efficient allocation of the available vehicle fleet for the distribution in a...

  • The Team Size Paradox: Knowledge Transfer and Process Loss Effects on Team Formation

    Creator:
    Méndez-Vázquez, Yaileen M.
    Abstract:
    Teamwork has become a popular operational strategy applied as part of workforce management plans in manufacturing and service industries. Teamwork has been commonly used in organizations to pursue different goals such as increase business operations agility, boost company productivity, improve quality in operations, increase company flexibility, promote collaborative learning, hasten...

  • Assessing Mass Diffusion Modeling in Premixed Flames

    Creator:
    Fillo, Aaron J.
    Abstract:
    Implementing multicomponent diffusion in numerical combustion studies is computationally expensive due to the challenges involved in computing diffusion coefficients. As a result, mixture-averaged diffusion treatments or simpler methods are used to avoid these costs. However, the accuracy and appropriateness of the mixture-averaged diffusion model has not been verified for three-dimensional...

  • Integration of Systems Thinking, Viable System Model, and System Dynamics toward Systemic Sustainability Assessment Methodology

    Creator:
    Tong, Anh B.
    Abstract:
    The developmental milestones of Sustainability are consistent with the post-normal versus traditional science, where transdisciplinary and policy/action research are among the important approaches to be added to traditional analysis. This shift requires a new perspective to look at the problem at hand: we are no longer considering a group of...

  • From Functional Modeling to Optimization : Risk and Safety in the Design Process for Large-Scale Systems

    Creator:
    McIntire, Matthew G.
    Abstract:
    In order to more effectively design large, complex systems, risk must be accounted for throughout the design process. A systematic way to account for risk is by using system model simulation. During the conceptual design phase, functional models can be drawn to help the engineer design their system's functional architecture....
