  • Coevolution and transfer learning in a point-to-point fleet coordination problem

    Creator:
    Yliniemi, Logan Michael
    Abstract:
    In this work we present a multiagent Fleet Coordination Problem (FCP). In this formulation, agents seek to minimize the fuel consumed to complete all deliveries while maintaining acceptable on-time delivery performance. Individual vehicles must both (i) bid on the rights to deliver a load of goods from origin to destination...

  • Assessing steel bevel gear design alternatives for sustainability performance through unit manufacturing process modeling

    Creator:
    Eastwood, Michael D.
    Abstract:
    As the growth in demand for sustainable manufacturing continues, companies must begin to make conscious design decisions with regard to the sustainability of their products. This means balancing economics of production with environmental and social performance. Thus, design and manufacturing engineers must consider economic, environmental, and social aspects simultaneously when...

  • Multi-Objective Optimization in Multiagent Systems

    Creator:
    Yliniemi, Logan Michael
    Abstract:
    Cooperative multiagent systems are used as solution concepts in many application domains including air traffic control, satellite communications, and extra planetary exploration. As systems become more distributed and complex, we observe three phenomena. First, these systems cannot be accurately modeled, rendering traditional model based control methods inadequate. Second, system parameters...

  • Multi Objective Aerodynamic Design in Formula SAE

    Creator:
    Arscott, Phillip J.
    Abstract:
    This thesis examines the effect of aerodynamics on Formula SAE cars. Due to the different objectives of the Formula SAE events, an understanding of the car's complete aerodynamic design is necessary. Using a half car computational fluid dynamics (CFD) model, a series of sensitivity studies are conducted to determine trends...

  • Evaluating Cultural Dimensions to Design Better User Interfaces

    Creator:
    Miller, Robert
    Abstract:
    Cultural differences between designers and users is an important aspect to consider when designing products for other countries. However, many prominent authors in the human factors engineering field have failed to specifically address how to identify and utilize cultural differences in user interface (UI) design. This research evaluated if design...

  • Floating Offshore Wind Array Systems Optimization off the US West Coast using an Extended Pattern Search Algorithm

    Creator:
    Forinash, Caitlin P.
    Abstract:
    The large wind resource off the United States West Coast has the potential to generate wind power for millions of homes, yet the high cost of energy for offshore wind power compared to traditional sources has slowed the development of offshore wind farms in the US. The four studies presented...

  • Composite Tools and Optimization in Racecars to Reduce Mass and Design Time

    Creator:
    Wagoner, Marshall
    Abstract:
    Designing a carbon fiber chassis for the Global Formula Race car has historically proven to be both time intensive and difficult. The goal of this thesis is to improve the design process for testing Global Formula Racing team's composite chassis sandwich panels. Consideration was taken regarding Formula SAE rules, and...

  • Automated Assembly Planning : From CAD Model to Virtual Assembly Process

    Creator:
    Rafibakhsh, Nima
    Abstract:
    Assembly planning is a crucial task for every manufacturing product. In general, assembly operations consume more than 30% of the total manufacturing time and cost. Therefore, any effort in optimizing assembly will have a significant impact on the economic success of manufacturing. Finding an optimal assembly plan by hand is...

  • Percent Area Visual Obscuration of F1 Racecar Canopies

    Creator:
    Jennings, Alex
    Abstract:
    Considering human product interactions early and often in the engineering design process may improve product quality, facilitate user safety, reduce time to market, decrease or eliminate the need for costly physical prototypes, and reduce expensive late stage design changes. Currently, F1 race cars do not include a cockpit canopy to...

  • Wave Energy Converter Array Optimization : Algorithm Development and Investigation of Layout Design Influences

    Creator:
    Sharp, Christopher J.
    Abstract:
    Realizing the vast amount of energy available in ocean waves, an industry has emerged that is progressing towards the deployment of grid–connected wave energy converters. Likely to be deployed in arrays, a challenge to the wave energy industry is maximizing the energy production of such arrays. We have been developing...
