  • An object oriented representation for mechanical design based on constraints

    Creator:
    McGinnis, Brian D.
    Abstract:
    A representation for the process of mechanical design, along with its computer implementation is presented and discussed. The representation consists of three fundamental concepts: design objects, constraints, and decisions. The design objects are the structures with which the physical artifacts of the design are described. A design object consists of...

  • Mechanical design under changing customer requirements case study : BugID

    Creator:
    Fagan, Chris R.
    Abstract:
    Customer requirements and engineering specifications will influence the direction of the design in any product, so it is crucial to make the requirements as stable as possible so quality designs can be produced on time within a budget. It would be optimal for requirements and specifications to remain constant but...

  • Risk-based design for multidisciplinary complex systems

    Creator:
    Farhangmehr, Farzaneh
    Abstract:
    The ultimate goal of large-scale design organizations are mainly to reduce costs and improve reliability and performance of systems while assessing how much risk (cost, schedule, scope) they can take and still remain competitive. To achieve this goal they need to develop tools to reach the most preferred design product...

  • Towards a guided framework for innovative engineering through the generation and evaluation stages of concept design

    Creator:
    Oman, Sarah Kay
    Abstract:
    This work proposes a framework of concept generation and evaluation that takes into consideration the benefit of creativity and innovation in current market trends. By educating engineers in how to increase creativity in concept design and assess it quantitatively, the next generation of designers will be a step ahead of...

  • A framework to model reliability and failures in complex systems during the early engineering design process

    Creator:
    O'Halloran, Bryan M.
    Abstract:
    An open area of research in complex systems is to move reliability and failure assessments earlier in the engineering design process. When compared to later design, early decisions are cost effective and have a large impact on the system. Standard methods are limited by the availability of data and often...

  • 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...

  • 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...

  • A multiagent approach to identifying innovation in design components

    Creator:
    Rebhuhn, Carrie M.
    Abstract:
    Innovation is a key element for a product to achieve market success, but identifying it within product or even defining the term is a difficult task. Identifying innovation has been approached in many different ways. Experts in design engineering may identify innovative designs based on an analysis of a product's...

  • 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...

  • Methodologies to improve reliability engineering in early design

    Creator:
    O'Halloran, Bryan M.
    Abstract:
    This thesis is the summation of two publications with the motivation to move reliability analysis earlier in the design process. Current analyses aim to improve reliability after components have been selected. Moving specific analyses earlier in the design process reduces the cost to the designer. These early design analyses provide...
