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...
Virtual environments involving Federations-of-Models (FoM) and Operators-in-the-Loop (OITL) offer a unique venue for investigating the engineering trade-space available for System-of-Systems (SoS) designs. Use of an OITL FoM environment early in the design process (i.e., during concept...
This praxis develops a simulation-based approach to analyzing the overall reliability of complex systems with high degrees of redundancy, time varying event rates, and the potential for common cause failures. This approach is compared to traditional analytic approaches, and is shown to have some...
The FY15 Department of Defense (DoD) enacted budget of $560.3 billion dollars funded DoD operations and acquisitions of complex military systems. The acquisition efforts were led by personnel who served in Key Leadership Positions (KLPs) from multiple disciplines to increase acquisition success...
Our research approach emphasized a comparison of various classification methods (“Decision Trees, Logistic Regression, Naïve Bayes, Linear Discriminant Analysis, Nearest Neighbors, Support Vector Machines”) and compared those with ensemble classifier models (“bagging” and “boosting”) to predict...
PurposeThe purpose of this paper is to explore how the application of Systems Engineering tools and techniques can be applied to rapidly process and analyze the vast amounts of data present in social media in order to yield practical knowledge for Command and Control (C2)...
Effects of Geographic and Demographic Dispersion on the Performance of Systems Engineering TeamsGlobalization and the increasing complexity of systems require collaboration across multidisciplinary teams. Systems Engineering (SE) teams are often geographically and demographically dispersed; such...
Exhaustion of current version of Internet Protocol version 4 (IPv4) addresses initiated development of next-generation Internet Protocol version 6 (IPv6) [82, 83]. IPv6 is acknowledged to provide more address space, better address design, and greater security; however, IPv6 and IPv4 are not fully...
Building owners, designers and constructors are seeing a rapid increase in the number of sustainably designed high performance buildings. These buildings provide numerous benefits to the owners and occupants to include improved indoor air quality, energy efficiency, and environmental site...
This dissertation presents research that focuses on efficient allocation of defense resources to minimize the damage inflicted on a spatially distributed physical network such as a pipeline, water system, or power distribution system from an attack by an active adversary. The allocation...
