Systems Analysis, Design, and Integration

Systems integration is a fundamental and critical aspect of systems engineering. Systems integration can involve the integration of any system components, including hardware, software, and policy. Also, it can involve "systems of systems", i.e., the integration of disparate systems.

Example Center. WICAT (Wireless Internet Center for Advanced Technology) is an NSF-Sponsored Industry/University Cooperative Research Center. UVa is one of three research university sites that constitute the overall Center. The other sites are Columbia University and Polytechnic Institute of New York. The UVa research site is directed by Barry Horowitz, Professor of Systems and Information Engineering. Research is principally funded by industry, with supporting funding from both UVa and NSF. The UVa site focuses its research efforts on rapidly reconfigurable wireless systems. The Systems Technology Integration Laboratory permits significant experimental support to the UVa site's technology development efforts. Currently the UVa site is engaged in collaborative efforts with a number of companies, including a mixture of larger and smaller companies, systems integration companies and component technology development companies. The collaborations include efforts with Lockheed-Martin, Accenture, Northrup/Grumman, Mitre, Cisco, the Virginia Transportation research Center, and others. Research has included efforts targeted at wireless sensor networks and on integrating large scale enterprise systems with mobile users and wireless information providers. The research has included exploring:

  1. advanced image compression technology for dynamic adjustments of delivery based on wireless communications congestion,
  2. utility-based information management concepts,
  3. game-theory based sub-system coordination concepts,
  4. automated power management of wireless components based on overall system-level considerations,
  5. application of advanced peer-to-peer networking technology for controlling situational information distribution,
  6. AI-based automation for supporting humans to rapidly reconfigure information flows and the corresponding network configurations, and
  7. automated self-testing of configuration for wireless sensor networks.

Mission areas that have been the focus for applying the Center's technology efforts include military systems, robotic systems, homeland security systems, and ground transportation systems.

Example project: Vehicle-Infrastructure Integration (VII) is defined as creating an enabling wireless communication infrastructure to support vehicle-to-vehicle and vehicle-to-infrastructure communications for safety and mobility applications. The full integration of vehicles and infrastructure has long been a vision of the surface transportation system, but lack of available enabling technology has prevented this vision from turning into reality. However, recent developments in information technology have led to the development of Dedicated Short Range Communications (DSRC). DSRC is a short to medium range communication technology that supports public safety and private operations in roadside-vehicle and vehicle-vehicle communications. DSRC is a complement to cellular communications providing high data rates, and it is useful when isolating relatively small communication zones is important.

The group's areas of expertise in systems integration include:

  • Transportation systems integration
  • Wireless systems integration
