- Strategic Analyses of Reliability and Maintainability: SoHaR has performed enterprise-level
reliability and availability analyses of FAA systems for national pacing airports,
terminal air traffic control facilities, and en-route facilities for enterprise-level
cost benefit analyses. The purpose of these analyses is to provide an analytical
basis for resource allocation for capital investment and staffing decisions.
- NIMS Resource Planning Model: SoHaR is developing a model to predict the impacts
of staffing, training, sparing, and other parameters on service level availability.
The model, based on discrete event simulation, is being developed in Java with the
capability of retrieving and analyzing data from existing FAA databases. This capability
will allow for tactical decisions based on timely and consistent data.
- Oceanic Air Traffic Control Architecture and Reliability Support: SoHaR supports
the Federal Aviation Administration in the overall system definition, requirements
formulation, project oversight, design reviews, test plans, and implementation issues
for the Oceanic Automation System and Advanced Oceanic Automation System upgrades.
- Reliability Evaluation of the National Airspace System: SoHaR evaluated reliability
and maintenance data from the National Airspace System (NAS) in order to determine
overall trends and identify critical areas. We have performed detailed analysis
on National Airspace Performance data for ARTS III, ARTS II, Host, CDC, and DCC
Systems. We have formulated reliability and fault tolerance related requirements
for upgrades to the FAA Oceanic automation system. We have also provide system engineering
support including top level architecture definitions and cost estimations to support
FAA Capital Improvement Plan proposals.
- Reliability and Fault Tolerant Support for the Voice Switching Control System (VSCS):
SoHaR assists the FAA in establishing reliability and availability requirements
for the VSCS and assessing their implementation.
- Software Reliability/Maintainability Requirements Development: SoHaR conducted a
formulation in the Air Traffic Control System Computer Replacement Program. It then
identified and tailored software standards, and developed a software quality specification.
