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...
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...
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...
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 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 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...
