Cost-Effective Mixed-Criticality Systems
Agency / Branch:
DOD / ARMY
Future Army and DoD systems will rely on greater functional integration and autonomy that create interactions among applications and resources that have mixed criticalities. WWTGs innovations in this project will benefit the Army (and other DoD branches) by providing: 1) A tool-assisted design strategies for composing mixed critical system architectures based on Aspect Containment Regions (ACRs) mapped onto system partitions, 2) Analysis methods for establishing and assessing the ACR mappings, 3) a means for run-time platform configuration from architecture models to set the characteristics of the partitioning and information flow in the deployed system. This enables a strong coupling between the validated architecture model and the deployed computing platform. A companion tool suite is used for analysis and certification using a model-based approach. In analyzing mixed critical architectures we utilize a component-based analysis approach centering on the representation of system security, safety, dependability and certification aspects within a comprehensive system architecture model. The process and tool can be used to reduce overall recertification costs while maintaining the required security, dependability, safety and real-time performance properties across the complete system life cycle.
