High Reliability Organizations are organizations that have fewer than the average number of high-consequence accidents. “Heinrich’s Law” states that the industrial average of the ratio of high-consequence accidents to total recordable accidents is 1:330. This represents an average of one...
With increasing Internet connectivity and traffic volume, recent intrusion incidents have reemphasized the importance of network intrusion detection systems for combating increasingly sophisticated network attacks. Techniques such as pattern recognition and the data mining of network events are...
Modern systems are becoming exponentially more complex and interconnected, particularly in software-intensive systems. Department of Defense (DoD) mandates for net-centric capabilities have greatly complicated the challenges for testing new and legacy systems that are employed in a system of...
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...
Today's National Airspace System (NAS) is managed using an aging surveillance radar system. Current radar technology is not adequate to sustain the rapid growth of the commercial, civil, and federal aviation sectors and cannot be adapted to use emerging 21st century airspace surveillance...
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...
Ever since the release of the Brundtland Report by the World Commission on Environment and Development (WCED, 1987), the sustainable development (SD) concept has been gaining more and more traction from a majority of research disciplines in the recent two decades. For instance, the impact of...
Problem management is not recognized as a system engineering process. Unlike risk management where risks could impact a project at some future date, problems impact the project now. Therefore, a robust problem management process should be established (similar to the risk management process...
This research investigates the instantiation of a Service-Oriented Architecture (SOA) within a hard real-time (stringent time constraints), deterministic (maximum predictability) combat system (CS) environment. There are numerous stakeholders across the U.S. Department of the Navy who are...
Modern society is increasingly dependent on the smooth operation of large scale technology supporting Earth based activities such as communication, electricity distribution, and navigation. This technology is potentially threatened by global geomagnetic storms, which are caused by the impact of...
The United States (U.S.) Federal Government has long had a need for highly secure communications. The National Security Agency (NSA) is responsible for the wide range of technologies to secure these communications. They realized, recently, that the development times for U.S. Government encryption...
Business process optimization allows businesses to remain competitive by allowing management to observe, analyze, and improve the operations of the organization. Using data and related business insights developed through applied analytic disciplines to drive business process optimization allows...
Each year, the Department of Defense (DoD) is provided with an appropriation and authorization act from Congress known as the Military Construction (MILCON) program. The DoD delegates this financial authority to subordinate units for the purpose of funding the design and execution of new...
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...
Over the past few decades, the public sector has seen significant change in the political and economic environment due to greater interdependencies between agencies and the private sector, globalization, and rapid technological change. The resulting uncertainty introduces a number of challenges...
This study employed the taxonomy of human factors presented in the Department of Defense Human Factors and Analysis and Classification System (based largely on the previous HFACS model developed by Wiegmann and Shappell, and Reason's "Swiss cheese" model) model to analyze and compare the human...
Market dynamics, technology spin-cycles, and affordability pressures are shaping development demands for medical devices.Model-based development offers a remedy for these pressures, with demonstrated ability to mitigate the complexity introduced. This dissertation will examine the program...
Integration Readiness Level (IRL) can be an effective systems engineering tool to facilitate integration of System of Systems (SoS). Further research in systems integration, analysis of major SoS integration data, and analysis of expert survey inputs to SoS integration can enhance the current IRL...
Project management has been a constant challenge for many practitioners, notably the U.S. Department of Defense (DoD) acquisitions community. While most DoD projects are technologically advanced, the tools and methods to manage these projects are the same as for simple, repetitive projects. The...
This paper examines the challenge of understanding uncertainty associated with military measures of effectiveness given incomplete and often imperfect information. With the migration towards a network-centric capability, the ability to represent, quantify, and aggregate uncertainty of information...
Maintenance personnel often lack the resources to determine which specific subassembly of a complex electronic system has failed but can only isolate the cause of failure to a subset of subassemblies. In these circumstances, the most efficient manner for replacing the suspect subassemblies is...
