A Preliminary Methodology For Automating Functional Modeling

Creator:: Edmonds, Katherine N.
Abstract:: This thesis is the combination of two research publications working towards automating functional modeling. Functional modeling is an underutilized yet critical tool for concept generation and product design. Understanding the difficulty both novice and expert designers have in implementing functional modeling in their design process, this research sets out to...

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...

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...

Environmental Sustainability During the Early Design Phase: Understanding the Uncertainty in the Use Phase, Visualization, and Automating Design Repository Curation

Creator:: Tensa, Melissa
Abstract:: The objective of this research is to support DfX considerations in the early phases of design, particularly Design for the Environment. In order to include DfX considerations, especially early in the design process, there needs to be access to knowledge and information that is usually only applicable further downstream in...

Pre-Prototyping Framework: An Early Design Prototyping Methodology for Human-Centered Products and Workplaces

Creator:: Ahmed, Salman
Abstract:: Prototyping is a crucial step in product design and development, but it is also known as the highest sunk cost. The top 20 Research and Development (R&D) department spends 142 billion dollars, yet 40 to 46 percent of this money goes into developing products that cannot even make to the...

Assessing Student Conceptual Understanding : Supplementing Deductive Coding with Natural Language Processing Techniques

Creator:: Arbogast, Christian
Abstract:: Assessing student conceptual understanding is a valuable method for gauging specific student learning outcomes but can be difficult and time consuming to measure. This research investigates the potential of automating some intermediary steps of a qualitative analysis of student conceptual understanding with tools from the field of Natural Language Processing...

Optimization Across Decomposition : A Multiagent Model of Collaboration in Decomposed System Design

Creator:: Hulse, Daniel E.
Abstract:: Complex engineered systems design is a collaborative activity. To design a system, experts from the relevant disciplines must work together to create the best overall system from their individual components. This situation is analogous to a multiagent system in which agents solve individual parts of a larger problem. Current multiagent...

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...

Functional analysis to inform early design decisions for novel systems with substantial operations and maintenance costs

Creator:: Algarra, Nathan
Abstract:: Long field-life systems are those for which operational, as opposed to capital, expenditures dominate the life time cost of the system. In established product categories, operational experience and historical maintenance data allows engineers to make informed decisions influencing maintenance during the early design stages when design changes are at their...
