The SEI, research community, and industry have performed a number of pilot projects to demonstrate the practicality of the architecture-centric virtual integration approach. (See news, publications and project/initiatives sections at https://wiki.sei.cmu.edu/aadl).
The ongoing System Architecture Virtual Integration (SAVI) initiative by aerospace industry is maturing the virtual system integration approach into an industrial practice. SAVI members include Boeing Commercial, Airbus, Embraer, Rockwell Collins, BAE Systems, Honeywell, Goodrich, NASA, FAA, and the US. Army. The US. Army is also investigating virtual integration in the form of virtual system integration labs (Virtual SIL) to support acquisition of software-reliant systems.
The SEI has been engaged in integrating AADL into an architecture-centric engineering practice through a range of pilot projects and by frameworks and methods tailored to the model-based approach. See related technical reports here.
The reliability validation and improvement framework outlines a technical strategy for systematically improving the quality of software-reliant systems with four pillars:
The value of SAE AADL as a modeling notation with well-defined semantics has been recognized by the research community, and AADL has become a technology platform of choice in integrating analytical research technologies (See the AADL Wiki and In the News).
Building on this concept of virtual integration, SEI research in this area is currently focusing on
