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...

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...

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...

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...

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...

Data Mining a Design Repository for Automating and Validating Functional Modeling

Creator:

Mikes, Alex B.

Abstract:

The purpose of this work is to build a foundation of understanding and methodologies as the steps toward automating functional modeling. We have achieved significant progress in the automatic generation of functional representations, which can be connected at the interface of components to create a functional model. This work highlights...

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...

Bio-Inspired Design of Vehicles that Operate in Complex Environments

Creator:

Jackson, Danielle M.

Abstract:

This dissertation focuses on defining underlying mechanisms to enable the bio-inspired design of aerodynamic and/or hydrodynamic vehicles that operate within complex environments. This dissertation introduces four overarching research gaps found in current bio-inspired design research and four corresponding approach questions that guide the framework of the presented research. This research...

Automated Rapid Manufacturing Feedback for Design Considering Advanced Joining Processes

Creator:

Chan, Rothanak

Abstract:

As manufacturing advancements continue to develop, designers must be able to consider these technologies during the design process. Unfortunately, many of these new technologies, such as additive and advanced joining, have many nuances that require expert knowledge to effectively apply. Additionally, new design techniques, such as topology optimization, allow users...

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...
