The future success of traffic management is contingent upon the advancement of information logistic systems. The ability to provide accurate, valid, and timely information is critical to the effectiveness of an intelligent transportation system’s ability to improve public safety and economic...
Soccer is the most popular sport worldwide. Over time, the importance of soccer has grown beyond the sports domain, making it a large industry, a source of national pride, and the center of public attention in most countries. Due to this increased significance, it is highly important for soccer...
As the activities of companies become global in nature there is an emerging need to understand the processes that lead to the success of large projects in which the core competency is centered in a parent company, an engineering development center that is located in a subsidiary company in...
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...
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...
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...
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...
Complex social systems are governed by policies that are designed and implemented by legislators, boards of directors, executives, and government officials. At policy inception, policy designers predict positive impacts on society and minimize known negative impacts, which are often seen as...
The organizational self-assessment process came to maturity during the Total Quality Management (TQM) movement. Although varying forms of the process had been utilized for many years, the first mature self-assessments, known as self-appraisals, were performed as a criterion for the Malcolm...
Multiple national and international research studies show that global warming is increasingly impacting communities. Global warming affects all continents and has been directly linked to many recent catastrophic weather-related disasters. Scientists and meteorologists predict that future natural...
Increasing complexity in modern systems, as well as cost and schedule constraints, require a new paradigm of system engineering to fulfill stakeholder needs. Challenges facing efficient trade studies include poor tool interoperability, lack of simulation coordination (design parameters) and...
Cyber-attacks have escalated, causing decision makers to assess the trade-offs required to protect their organizations from such attacks. The use of benchmarking techniques to reduce cyber security risks would allow decision makers to use both qualitative and quantitative analyses. Systems...
Early systems engineering has been emphasized as a critical success factor within the U.S. defense acquisition community. With the trend of system complexity, technology dependencies, and interoperability requirements, defense acquisitions frequently suffer schedule slips and cost overruns. After...
In recent years, with budgetary constraints and ever-changing mission requirements, the government and private industries have shifted their focus towards component based system development. The development of systems with commercial off-the-shelf components expedites the development process and...
Summary of contributions of this study: This study contributes new knowledge regarding the prescriptive utility of business intelligence systems and explicit knowledge objects in evidence-based management, and proposes a framework to better facilitate the management of business intelligence...
Effective and efficient risk management processes include the use of high fidelity modeling and simulation during the concept exploration phase as part of the technology and risk assessment activities, with testing and evaluation tasks occurring in later design development phases. However, some...
