Spacecraft Propulsion Systems Engineering and Modeling

UAH's Spacecraft Propulsion Systems Engineering and Modeling project is focused on the support of the Reaction Control System (RCS) for NASA's Ares I launch vehicle. The developments of the pressurization system model and the overall propulsion system model are priorities for...

Validation of Convective Initiation Using GOES

The Geostationary Operational Environmental Satellites (GOES) are in geosynchronous orbits that allow them to monitor a fixed spot on the Earth's surface. Data is transmitted and archived at fifteen minute intervals. This allows scientists to monitor and track weather...

Defining the Meaning of a Major Modeling and Simulation Change as Applied to Accreditation

Increasingly, decisions are being made based partially or entirely on models. These decisions may be quite important, with the potential of serious or unacceptable consequences if an incorrect decision is made. The models used to support the decisions may have been newly...

Low-Demand Inventory Stocking Strategies

A simple question is how much stock one should hold on hand in anticipation of future need. Holding stock in inventory costs money, so a balance must be struck between the cost of inventory stock and the cost of unmet demand. The Inventory Analyst (IA) package has been...

Metric of Evil

Beginning with an initial concept and model provided by the U. S. Army System Simulation and Development Directorate (SSDD), the University of Alabama in Huntsville (UAH) has developed and tested a “Metric of Evil,” a quantitative model of the harm associated with military...
