  • Energy use coefficients for irrigation system materials

    Creator:
    Daskalakis, George H.
    Abstract:
    Finite, uncertain, and increasingly expensive energy resources require a better understanding of energy utilization in all sectors of the national economy including agriculture. A significant portion of energy used in agriculture is required for the manufacturing, installation, transporting, and operation of irrigation systems. Quantification of the amounts of energy used...

  • A product development process measurement methodology applied to small manufacturing companies

    Creator:
    Schlegel, Stephen C.
    Abstract:
    The implementation of concurrent engineering into many large companies has greatly improved their product development processes. These companies have seen significant gains in quality and customer satisfaction with reduced product costs, defects, and time-to-market (Lake, 1992). Many large companies have successfully employed this relatively new product development philosophy. However, smaller...

  • Linking equations for the analysis of a serial automated workstation system

    Creator:
    Nagarajan, Raghavendran D.
    Abstract:
    In this research, an analytical model for analyzing a production line consisting of a series of automated workstations with infinite buffers is developed. Automated workstations are assumed to have deterministic processing times, and independent exponentially distributed operating time between failures and repair times. The analytical model starts with existing results...

  • Analyzing manufacturing system changes using discrete event simulation

    Creator:
    Baker, Eric S.
    Abstract:
    This research studied the effects of changing from a traditional manufacturing system to a cell manufacturing system in a value-added wood products company. Discrete event simulation was used to describe the current system and the proposed new systems. Parts were separated into part families that shared similar processing requirements. From...

  • The development and application of asystemic human error identification and remediation methodology

    Creator:
    Lee, Wei-Tau
    Abstract:
    This thesis describes a Systemic Vulnerability Identification and Remediation (SVIR) methodology that identifies human fallibilities and errors in complex technical processes, and recommends remediations for the errors, based on human factors principles and guidelines. The objectives of the research described in the thesis are the development of the methodology and...

  • Process-based modeling for cradle-to-gate energy and carbon footprint reduction in product design

    Creator:
    Alsaffar, Ahmed J.
    Abstract:
    Interest in accounting for environmental impacts of products, processes, and systems during the design phase is increasing. Numerous studies have undertaken investigations for reducing environmental impacts across the product life cycle. Efforts have also been launched to quantify such impacts more accurately. Life cycle energy consumption and carbon footprint are...

  • A Manufacturing Process Design for Producing a Membrane-based Energy Recovery Ventilator with High Aspect Ratio Support Ribs

    Creator:
    Kawula, Steven P.
    Abstract:
    Heating, ventilation, and air conditioning systems represent nearly half of building energy usage in the United States. Recent building regulations requiring increased air turnover within buildings will result in even greater air conditioning usage. To alleviate these concerns, membrane-based heat-and-moisture exchangers known as energy recovery ventilators have been developed to...

  • A Techno-Economic Assessment Methodology for Advanced Additive and Joining Processes

    Creator:
    Malshe, Harsha A.
    Abstract:
    Integrated manufacturing systems, a combination of subtractive, additive, and joining processes, provide a competitive advantage for manufacturing organizations. As product designs become more complex and capital more scarce, an ideal combination of advanced manufacturing technologies (e.g., powder bed fusion or friction welding), in tandem with traditional subtractive manufacturing systems, can...

  • Integrating product design and manufacturing process : a framework and implementation

    Creator:
    Li, Yu-An
    Abstract:
    The importance of integrating design and manufacturing becomes apparent when the increase in the degree of difficulty of change is observed as the product development proceeds from concept to production in a serial engineering process. The greatest opportunity in design for manufacture occurs at the initial design stage before any...

  • An information modeling framework and desktop application to compose unit manufacturing process models for sustainable manufacturing assessment

    Creator:
    Smullin, Matteo M.
    Abstract:
    The demand from consumers for more sustainable products, and the need to comply with government regulations motivates manufacturers to evaluate their operations for opportunities to reduce environmental impact and improve economic competitiveness. Manufacturers have actively improved the sustainability performance of their products through the use of sustainability assessment methods and...
