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...

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...

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...

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...

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...

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...

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 risk-informed decision making framework accounting for early-phase conceptual design of complex systems

Creator:: Van Bossuyt, Douglas L.
Abstract:: A gap exists in the methods used in industry and available in academia that prevents customers and engineers from having a voice when considering engineering risk appetite in the dynamic shaping of early-phase conceptual design trade study outcomes. Current methods used in Collaborative Design Centers either collect risk information after...

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...

Exploring experimental test stand design and operation within a system reliability research methodology

Creator:: Koopmans, Michael, 1986-
Abstract:: In cases where complex systems routinely experience extreme operating conditions, preventative maintenance is often employed to guard against system failure. Yet, with accessible real-time data and the standard practice becoming prohibitively expensive, the test stand can serve as a vital contributor to the development of system health and reliability estimations....
