Application Of Theory Of Constraints (Toc) In Managing Project Information Constraints, Ferdinand Z. Prantl Apr 2020

Application Of Theory Of Constraints (Toc) In Managing Project Information Constraints, Ferdinand Z. Prantl

Engineering Management & Systems Engineering Projects for D. Eng. Degree

The scope of this doctoral project is the non-traditional application of Drum-Buffer-Rope (DBR) from the area of Theory of Constraints (ToC) in mitigating disruption in distribution facilities during phased upgrades caused by information constraint. The relevance of this project is that industrial equipment upgrades pose a significant risk of disrupting the operation of automated distribution facilities. It is partly due to a very high expected availability rate, as well as tight coupling with other upstream and downstream elements of the larger supply chain network. As a consequence of disruption in this scenario, losses incurred not only within the facility being …


A Bridge And Engine Room Staffing And Scheduling Model For Robust Mission Accomplishment In The Littoral Combat Ships, John P. Cordle Apr 2019

A Bridge And Engine Room Staffing And Scheduling Model For Robust Mission Accomplishment In The Littoral Combat Ships, John P. Cordle

Engineering Management & Systems Engineering Projects for D. Eng. Degree

The Navy’s Littoral Combat Ships were designed to be relatively small surface vessels for operations near a littoral shore theater. These ships were envisioned to be highly automated, networked, agile, stealthy surface combatants capable of defeating anti-access and asymmetric threats in the littorals with minimum manpower. To date, however, some of these ships have experienced significant engineering and propulsion plant failures that impacted mission accomplishment and were attributable, at least in part, to under staffing and over scheduling the human component of the automation-human operational environment. The critical human components on the Littoral Combat Ship are bridge and engine room …


A Hierarchical Core Reference Ontology For New Technology Insertion Design In Long Life Cycle, Complex Mission Critical Systems, Kevin J. Michael Apr 2019

A Hierarchical Core Reference Ontology For New Technology Insertion Design In Long Life Cycle, Complex Mission Critical Systems, Kevin J. Michael

Engineering Management & Systems Engineering Projects for D. Eng. Degree

Organizations, including government, commercial and others, face numerous challenges in maintaining and upgrading long life-cycle, complex, mission critical systems. Maintaining and upgrading these systems requires the insertion and integration of new technology to avoid obsolescence of hardware software, and human skills, to improve performance, to maintain and improve security, and to extend useful life. This is particularly true of information technology (IT) intensive systems. The lack of a coherent body of knowledge to organize new technology insertion theory and practice is a significant contributor to this difficulty. This research organized the existing design, technology road mapping, obsolescence, and sustainability literature …


A Common Knowledge Engineering Framework For Data Assimilation, Correlation, And Extrapolation (Dace), Edward P. Weaver Apr 2015

A Common Knowledge Engineering Framework For Data Assimilation, Correlation, And Extrapolation (Dace), Edward P. Weaver

Engineering Management & Systems Engineering Projects for D. Eng. Degree

The Common Knowledge Engineering Framework for Data Assimilation, Correlation, and Extrapolation (DACE) project is focused on providing a software centric general framework for advanced processing and analysis of data. This translates to researchers, scientists, engineers, and system architects not having to program a new application but rather to define the system configuration, process, and processing that is needed to perform a specific functionality. This makes the limitation of the application the end users ability to fully define the functional requirements and setup the framework accordingly.

This doctoral project will provide the details to the system definition, standards, metrics, schedule, and …


A Sociotechnical Systems-Based Process To Facilitate The Development Of A Change Intervention Deployment Plan, Jorge Luis Nadal Jul 2013

A Sociotechnical Systems-Based Process To Facilitate The Development Of A Change Intervention Deployment Plan, Jorge Luis Nadal

Engineering Management & Systems Engineering Projects for D. Eng. Degree

The purpose of this project was to formulate a process to facilitate the development of an effective change intervention deployment plan. The premise is that without a proper deployment plan, the successful implementation of a change intervention in an organization will be slow and require multiple revisions. This research utilized a Sociotechnical Systems (STS) approach to analyze the implementation of a major change intervention.

This research was in part prompted by a request by management of the U.S. Army Corps of Engineers (USACE) for the researcher to examine why it has taken so long to successfully implement this large-scale change …


Meta-Heuristics Analysis For Technologically Complex Programs: Understanding The Impact Of Total Constraints For Schedule, Quality And Cost, Henry Darrel Webb Jul 2012

Meta-Heuristics Analysis For Technologically Complex Programs: Understanding The Impact Of Total Constraints For Schedule, Quality And Cost, Henry Darrel Webb

Engineering Management & Systems Engineering Projects for D. Eng. Degree

Program management data associated with a technically complex radio frequency electronics base communication system has been collected and analyzed to identify heuristics which may be utilized in addition to existing processes and procedures to provide indicators that a program is trending to failure. Analysis of the collected data includes detailed schedule analysis, detailed earned value management analysis and defect analysis within the framework of a Firm Fixed Price (FFP) incentive fee contract.

This project develops heuristics and provides recommendations for analysis of complex project management efforts such as those discussed herein. The analysis of the effects of the constraints on …


Development Of Risk Uncertainty Factors From Historical Nasa Projects, Tahani R. Amer Jan 2011

Development Of Risk Uncertainty Factors From Historical Nasa Projects, Tahani R. Amer

Engineering Management & Systems Engineering Projects for D. Eng. Degree

NASA is a good investment of federal funds and strives to provide the best value to the nation. NASA has consistently budgeted to unrealistic cost estimates, which are evident in the cost growth in many of its programs. In this investigation, NASA has been using available uncertainty factors from the Aerospace Corporation, Air Force, and Booz Allen Hamilton to develop projects' risk posture. NASA has no insight into the developmental of these factors and, as demonstrated here, this can lead to unrealistic risks in many NASA Programs and projects (P/p). The primary contribution of this project is the development of …
