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...

Modeling innovativeness in consumer products with the influence of environmental sustainability

Creator:: Gilchrist, Brady
Abstract:: This thesis is the result of two research publications, which together form a framework for the evaluation of product innovativeness with potential future applications to early design. Innovation is a challenging concept to quantify. Experts seemingly have a grasp of what innovation is when they see it, however this evaluation...

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...

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...

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...

Design of an accessible sleeper compartment for next generation passenger rail : investigation of user needs and application of human factors through digital human modeling

Creator:: Tabattanon, Kamolnat
Abstract:: As the trend of increasing age, weight, size, and disability within the population continues to increase, the demand for accessible transportation is expected to increase as well. Accessible and inclusive transportation is key in providing independent, barrier-free mobility for persons with accessibility needs. This thesis describes work completed in partial...

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...

Design of Complex Engineered Systems Using Multiagent Coordination

Creator:: Soria Zurita, Nicolás Francisco
Abstract:: This thesis is the combination of two research publications working toward a unified strategy in which the design of complex engineered systems can be completed using a multiagent coordination approach. Current engineered system modeling techniques segment large complex models into multiple groups to be simulated independently. These methods restrict the...

Characterization of expert solutions to inform instruction and assessment in an industrially situated process development task

Creator:: Sherrett, Ben U.
Abstract:: What constitutes a quality solution to an authentic task from industry? This study seeks to address this question through the examination of two expert solutions to an authentic engineering task used in the Chemical, Biological and Environmental Engineering curriculum at Oregon State University. The two solutions were generated by two...

Investigation of volumetric coupling effects on particle-laden turbulent flows at dilute to moderate loadings

Creator:: Cihonski, Andrew John
Abstract:: Particle-laden turbulent flows are of great importance in many industrial applications and are sufficiently complex to require multiple methods of study to provide a better understanding of the dominant physical mechanisms present in these processes. This work on large-eddy simulation of particle-laden flows seeks to help provide the building blocks...
