A Framework to Evaluate the Risk of Human- and Component-related Vulnerability Interactions

Creator:: Irshad, Lukman
Abstract:: Most accidents and malfunctions in complex engineered systems are attributed to human error. However, a closer inspection would reveal that such mishaps often emerge as a result of poor design and human- and component-related vulnerabilities acting together. To fully understand and mitigate potential risks, the effects of such interactions between...

A Computational Framework for Resilience-Informed Design

Creator:: Hulse, Daniel E.
Abstract:: It is desirable for complex engineered systems to perform missions efficiently and economically, even when these missions' complex, variable, long-term operational profiles make it likely for hazards to arise. It is thus important to design these systems to be resilient so that they will actively prevent and recover from hazards...

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...

The Effects of Modularity on Cascading Failures in Complex Engineering Systems

Creator:: Parker, Elizabeth M.
Abstract:: To design engineering systems that have improved reliability, it is important to understand what kind of system faults they will be susceptible to. Mitigation strategies are important to ensuring the performance of these engineering systems. Understanding how the modularity of complex engineering systems affects the risk of devastating failures such...

The Function-Human Error Design Method (FHEDM)

Creator:: Soria Zurita, Nicolás F.
Abstract:: This research presents a methodology to identify and analyze human-system interactions, and their potential failure modes using a functional decomposition approach during the early system design stage. The fundamental research contribution of this work is the development of a framework to identify associations between physical user-product interactions, generic human errors...

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...
Resource Type:: Masters Thesis

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...
Resource Type:: Masters Thesis

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...

Design of robust infrastructure systems incorporating user behavior

Creator:: Piacenza, Joseph R., III
Abstract:: Infrastructure systems are a critical component supporting today's modern society. From power grids to traffic networks, we rely on these systems to perform as intended, despite the various sources of uncertainty present in their operation. Designing for system robustness can help mitigate the impact of failures caused by unexpected events....

Evaluating complex engineered systems using complex network representations

Creator:: Haley, Brandon M.
Abstract:: This thesis is the combination of two research publications working toward a unified strategy in which to represent complex engineered systems as complex networks. Current engineered system modeling techniques segment large complex models into multiple groups to be simulated independently. These methods restrict the evaluations of such complex systems as...
