of Adaptive Autonomy (AA). This study presents an expert system realization
of the AA framework, referred to as Adaptive Autonomy Expert System (AAES).
The proposed AAES is based on the extracted rules from the Experts
Judgment on proper Levels of Automation (LOA) for various environmental
conditions, modeled as Performance Shaping Factors (PSFs). Decision fusion
method is used as expert system inference engine, where eight decision
fusion methods are developed as prospective ones. The AAES is realized
in the practical case of electric power Utility Management Automation
(UMA) for the Greater Tehran Electricity Distribution Company (GTEDC).
The practical list of PSFs and the judgments of GTEDCs experts
are used as the expert system rule base in this research. The results
of implementing the proposed AAES to GTEDCs network are evaluated
according to two criteria: average error and error margin. Five out of
eight decision fusion methods are proven to be suitable inference engines,
due to both criteria. Evaluation of the results shows that the proposed
AAES can estimate proper LOAs for GTEDCs UMA system, which change
due to the changes in PSFs; thus providing a dynamic (adaptive) LOA scheme
for UMA.]]>Alexandre, L.A., A.C. Campilho and M. Kamel,20012212831289Bloch, I.,1996265267Bradshaw, J.M.,20032003Daniels, J., P.W. Werner and A.T. Bahill,20014190212Endsley, M.R., B. Bolte and D.G.
