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...

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...

Analytical method for the prediction of reliability and maintainability based life-cycle labor costs

Creator:: Fitzpatrick, Mark W.
Abstract:: An analytical method for predicting life-cycle maintainability labor costs is developed. The purpose of the analytical method is to allow the evaluation of products, based on life-cycle labor cost, early in the design process. The Boeing 737-300/400/500 Bleed Air Control System is used as a test model, and the results...

Optimal troubleshooting plan for a complex electro-mechanical system

Creator:: Durgi, Parthsarathy
Abstract:: The decision sequences used for troubleshooting of complex electro-mechanical systems are often ad hoc and less than optimal. This research investigated Decision Analysis and Bayesian Networks for generating an optimal decision sequence for troubleshooting. The model that was used in this research was the bleed air control system of the...

Diagnostic analysis for mechanical systems

Creator:: Henning, Scott A.
Abstract:: An analysis and modeling method of the diagnostic characteristics of a mechanical or electromechanical system is presented. Diagnosability analysis is especially relevant given the complexities and functional interdependencies of modern-day systems, since improvements in diagnosability can lead to a reduction of a system's life-cycle costs. The diagnosis process of a...

Understanding Designer Mental Models to Support Computer Directed Analogical Design

Creator:: Arlitt, Ryan M.
Abstract:: Analysis of alternative concepts has a significant impact on design project outcomes, and yet many design teams fail to consider a significantly broad range of conceptual solutions. Within the realm of conceptual design exists a technique called design by analogy (DBA) -- the practice of reapplying old solutions to new...
