Abstract:

	The complexity of spacecraft in-flight operational systems has led to the need to
support system operators with intelligent technologies. Modeling the operator's cognitive
processes is necessary for the development of these technologies. The project will
employ an innovative tool and methodology based on multi-dimensional scaling (MDS)
for capturing the cognitive structures of space-crew operators. This methodology
is innovative because, unlike existing techniques, it is quantitative, formal, and
replicable, and it accesses the underlying structure of an operator's conceptual
representation. Existing knowledge elicitation tools, in contrast, are qualitative
and heuristic; focus only on an operator's procedural knowledge; and can be more
useful in unanticipated operational conditions. An automated, knowledge-acquisition,
MDS-based shell will be developed in Phase II, based on the design and techniques
developed in Phase I.

Potential Commercial Application:

Potential Commercial Applications: Automated, knowledge-acquisition tools would apply
in expert systems development, operator-system interface development, and training
system design.
