PROJECT
The embedded control and information
systems deployed in complex real-time systems provide a
sophisticated set of functions that must deliver safe and dependable
mission critical functions. When considering the application domain,
safety and system certification activities can become a formidable
task in each development spiral. As the system evolves and is
maintained, the need to repeat the certification process represents
a significant contributor to the life cycle cost structure.
WWTG offers an innovative and practical approach for detailing how
high confidence technologies can be implemented within critical
embedded control systems, including complex fly-by-wire systems. Our
approach centers on the representation of system dependability,
safety and certification aspects within a comprehensive system
architecture model. This model and a supporting set of analysis
tools enable system designers to make effective design trade-offs
that lead to reduced overall recertification costs while maintaining
the required dependability and safety properties across the complete
system life cycle. These tools are equally applicable for the
analysis of fielded systems that require increased reliability or
availability.
