Emergency Diesel-Electric Generator Set Maintenance And Test Periodicity, Stephen John Fehr
Emergency Diesel-Electric Generator Set Maintenance And Test Periodicity, Stephen John Fehr
Engineering Management & Systems Engineering Theses & Dissertations
Manufacturer and industry recommendations vary considerably for maintenance and tests of emergency diesel-electric generator sets supporting critical operations power systems facilities. There is little consistency among sets of similar technology, and manufacturers and their representatives often provide contradictory guidance. As a result, periodicity of emergency diesel-electric generator set maintenance and tests varies considerably in practice. This work proposes and tests a research and analysis framework to develop parametric regression survival models of modern diesel-electric generator sets in emergency standby duty as a function of maintenance periodicity, test periodicity, and other predictors. Within this framework, predictors are developed from common maintenance …
Time-Based Collision Risk Modeling For Air Traffic Management, Alan E. Bell
Time-Based Collision Risk Modeling For Air Traffic Management, Alan E. Bell
Engineering Management & Systems Engineering Theses & Dissertations
Since the emergence of commercial aviation in the early part of last century, economic forces have driven a steadily increasing demand for air transportation. Increasing density of aircraft operating in a finite volume of airspace is accompanied by a corresponding increase in the risk of collision, and in response to a growing number of incidents and accidents involving collisions between aircraft, governments worldwide have developed air traffic control systems and procedures to mitigate this risk. The objective of any collision risk management system is to project conflicts and provide operators with sufficient opportunity to recognize potential collisions and take necessary …
Graphical Display Of The Effect Of Three Cash Flow Elements For Sensitivity Analysis, Kawintorn Pothanun
Graphical Display Of The Effect Of Three Cash Flow Elements For Sensitivity Analysis, Kawintorn Pothanun
Engineering Management & Systems Engineering Theses & Dissertations
Sensitivity analysis is one of the most important analysis techniques in a decision making process. The analytic intent behind sensitivity analysis is the variation of parameters in data models, and the examination of the effect of these variations on the outcome of the models. There are four primary benefits from conducting a sensitivity analysis: (a) sensitivity analysis facilitates the decision makers' development of recommendations, (b) sensitivity analysis serves as a tool for communication among stakeholders or decision makers in a project or an organization, (c) sensitivity analysis increases overall understanding of the decision models, and (d) sensitivity analysis serves as …
Systems Theory Based Framework For Competency Models, Joseph M. Bradley
Systems Theory Based Framework For Competency Models, Joseph M. Bradley
Engineering Management & Systems Engineering Theses & Dissertations
The purpose of this research was to develop and apply a systems theoretic framework for design, analysis and transformation of competency models using an inductive research design. This research examines the origins and development of competency models from a systems theoretic perspective. Competency models have been largely developed by a comparative method first proposed by McClelland, or the use of Delphi method survey techniques. The assumption that a population containing an exemplar and fully successful members would enable population of a holistic competency model has reported numerous failures. Similarly, reporting on the use of Delphi methods has focused on attempting …
An Investigation Into The Analysis Of Truncated Standard Normal Distributions Using Heuristic Techniques, John Walter Ralls
An Investigation Into The Analysis Of Truncated Standard Normal Distributions Using Heuristic Techniques, John Walter Ralls
Engineering Management & Systems Engineering Theses & Dissertations
Standard normal distributions (SND) and truncated standard normal distributions (TSND) have been widely used and accepted methods to characterize the data sets in various engineering disciplines, financial industries, medical fields, management, and other mathematic and scientific applications. For engineering managers, risk managers and quality practitioners, the use of the standard normal distribution and truncated standard normal distribution have particular relevance when bounding data sets, evaluating manufacturing and assembly tolerances, and identifying measures of quality. In particular, truncated standard normal distributions are used in areas such as component assemblies to bound upper and lower process specification limits.
This dissertation presents a …
An Instrument To Assess Individual Capacity For System Thinking, Ra'ed M. Jaradat
An Instrument To Assess Individual Capacity For System Thinking, Ra'ed M. Jaradat
Engineering Management & Systems Engineering Theses & Dissertations
The purpose of this research was to develop and deploy a new systems thinking instrument to assess individual capacity for systems thinking using an inductive research design. While technology has been increasing exponentially, the corresponding methods to harness those technological advances, and the problems they have spawned, is lagging. While there is a broad collection of systems based methods, techniques, technologies, and tools that can be used in dealing with complex problems, these are predicated on an individual's capacity for engaging a level of systems thinking commensurate with their effective, deployment. Research based methods to determine individual capacity for systems …
