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...

Dissertation
A framework to model reliability and failures in complex systems during the early engineering design process

Creator:

O'Halloran, Bryan M.

Abstract:

An open area of research in complex systems is to move reliability and failure assessments earlier in the engineering design process. When compared to later design, early decisions are cost effective and have a large impact on the system. Standard methods are limited by the availability of data and often...

Dissertation
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...

Dissertation
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...

Dissertation
Methodologies to improve reliability engineering in early design

Creator:

O'Halloran, Bryan M.

Abstract:

This thesis is the summation of two publications with the motivation to move reliability analysis earlier in the design process. Current analyses aim to improve reliability after components have been selected. Moving specific analyses earlier in the design process reduces the cost to the designer. These early design analyses provide...

Masters Thesis
Risk-based design for multidisciplinary complex systems

Creator:

Farhangmehr, Farzaneh

Abstract:

The ultimate goal of large-scale design organizations are mainly to reduce costs and improve reliability and performance of systems while assessing how much risk (cost, schedule, scope) they can take and still remain competitive. To achieve this goal they need to develop tools to reach the most preferred design product...
