to information is vital for mechanics doing maintenance on
aircraft. Maintenance must be completed under time constraints,
and a significant portion of a mechanic's time is spent looking
for appropriate information from other mechanics or from paper
documentation. Reports must be read and written, information
sources queried and consulted, and information must be stored
and organized. Not only does this take considerable time,
it also results in inconsistent updates, ad hoc handwritten
documentation, and lack of access to old but useful information
sources. In order to address these problems, we have developed
RETSINA infrastructure for use in wearable computers for mechanics'
decision support during aircraft maintenance.
agent-supported process, a mechanic carries a wearable computer
as he completes his maintenance tasks. When he encounters
a discrepancy in his inspection, the mechanic fills out a
form on his computer.
analyzes the form and seeks out relevant information from
agents. The system then displays the processed information
recommendations and files the form for future use.
of wearable computers with agents include automatic location
and retrieval of information relevant to repairs, utilization
of historical repair data, increased efficiency of access
to information from manuals, and reduction in average time
for repair. The overall result is timely, quality maintenance.
