Systems Engineering
ATCorp systems engineering activities adapt the standard principles outlined by the International Council on System Engineering and other standards organizations to the requirements of our customer organizations.
Our systems engineering group has extensive experience with:
- Enterprise Architecture – Enterprise architecture
is a rigorous description of the structure of an enterprise, its
decomposition into subsystems, the relationships between the subsystems,
the relationships with the external environment. ATCorp developed enterprise
architectures for three terminal systems: Runway Status Lights, Low-cost
Ground Surveillance System and the Terminal Automation Modernization and
Replacement System. ATCorp engineers developed tools to facilitate timely
and accurate development and editing of the Enterprise Architecture Products,
enabling the human to focus on development of accurate, graphical
representations of operations and systems and relegating to the computer
the drudgery of producing large, complex matrices of detailed, abstract
information.
- Safety Risk Management – Safety Risk Management provides
a systematic and integrated method for managing safety of ATCorp and navigation
services in the National Airspace System (NAS). ATCorp engineers have led development
of FAA standard safety risk management products, such as Program Safety Plans,
the Preliminary Hazard Analysis, and the Operational Safety Analysis.
- Requirements Analysis – ATCorp system engineers have led
the development of procurement requirements for large-scale systems, performing,
operational evaluation, functional decomposition, and performance analysis. We've
led Subject Matter Expert reviews, retaining requirements genealogy and complex
issues tracking.
- Risk Management – ATCorp has performed several risk management
assignments for the FAA. These include design and oversight of a risk mitigation
process for the Advanced Automation System that correctly predicted a processor
performance problem early in its design cycle. We also conducted a safety risk
assessment for the Final Approach Runway Occupancy Signal. That assessment
augmented the FAA's standard risk management approach with a custom-designed
state-transition diagram depicting the system states, both valid and invalid,
and the likely outcome of each. The state-transition diagram was used to assess
technical risk and develop risk mitigation strategies.
