TECHNICAL ABSTRACT (LIMIT 200 WORDS)
We propose to create model-based simulation and analysis tools for
risk management throughout the system life cycle. Rather than using
traditional approaches based on failure events in static engineering
designs, we will treat a system as a dynamic process that is
continually adapting to achieve its ends and to react to changes in
itself and its environment. The original design must not only enforce
appropriate constraints on behavior to ensure safe operation, but the
system must continue to operate safely as changes occur. The process
leading up to an accident (loss event) can be described in terms of an
adaptive feedback function that fails to maintain safety as
performance changes over time to meet a complex set of goals and
values. Using this definition of risk management, we will extend our
commercial system engineering tool set to include model-based
simulation and analysis of risk throughout the system life cycle,
including complex human decision-making, software errors, system
accidents (versus component failure accidents), and organizational risk
factors.

POTENTIAL NASA COMMERCIAL APPLICATION(S) (LIMIT 150 WORDS)
The results of this SBIR research will be potentially applicable to
every NASA project where significant losses can result from the
operation or lack of operation of the system. It should be
particularly important in systems with significant software and human
automation interaction components and in large projects where
management decisions about risk are critical and need to be supported.

POTENTIAL NON-NASA APPLICATION(S) (LIMIT 150 WORDS)
The results of this SBIR project will be applicable to risk management
in any safety-critical system. SpecTRM-RL, the modeling language as
well as the more SpecTRM requirements specification and analysis
tools, are currently in use in the automotive and aerospace industries
and being evaluated for use in the medical device industry as well.
