This research presents an innovative means of gauging Systems Engineering effectiveness through a Systems Engineering Relative Effectiveness Index (SE REI) model. The SE REI model uses a Bayesian Belief Network to map causal relationships in government acquisitions of Complex Information Systems...
The purpose of this dissertation lies in integrating knowledge management (KM) and quality management (QM), and in demonstrating the operational effectiveness of a KM/QM strategy through quantitative empirical research. The research framework proposed herein is based on the KM/QM strategy,...
Systems engineers are faced with the challenge of adhering to broad systems engineering policies, while simultaneously tailoring systems engineering processes to meet the unique challenges facing their projects. Tailoring is often performed ad hoc, and determining which stages, steps, and...
Building complex physics-based systems in a timely cost-effective manner, that perform well, meet diverse user needs, and have no bad emergent behaviors is a challenge. To meet these requirements the solution is to model the physics-based system before building it. Modeling and Simulation...
With pressure on the U.S. Defense Acquisition System (DAS) to reduce cost overruns and schedule delays, system engineers’ performance is only as good as their tools. Recent literature details a need for 1) objective, analytical risk quantification methodologies over traditional subjective...
While system complexity is on the rise across many product lines, the resources required to successfully design and implement complex systems remain constrained. Because financiers of complex systems development efforts actively monitor project implementation cost, project performance models are...
The Department of Defense and the aerospace industry are responsible for decades of successful implementation of systems engineering process models used for the development of complex systems. The process models implemented throughout acquisition life cycles have proven to be comprehensive and...
AbstractA Systems Engineering Framework for Implementing aSecurity and Critical Patch Management Process in Diverse Environments(Academic Departments' Workstations)Use of the Patch Vulnerability Management (PVM) process should be seriously considered for any networked computing system. The PVM...
Flight safety has been an important topic for both academia and the industry. Aviation experts and authorities, as well as commercial airline administrators, have always been looking for improvements in the safety of flights. Researchers, on the other hand, have tried to model avionic fatalities...
In 2008, the Government Accountability Office (GAO) performed a study on 11 Department of Defense (DoD) programs and compared how requirements were developed between DoD and private industry. The study found that the DoD did not follow good Systems Engineering practices when developing...
