Abstract:
Operators of large-scale industrial process plants such as nuclear power stations and
chemical production plants are faced with a critical and complex task when
confronted with disturbances in normal operation caused by technical failures or
maintenance errors. Great care must be taken to prepare and support the operators
during such situations. Procedural systems are provided, training on full-scale highfidelity
simulators is often a prerequisite and decision-support systems are starting to
be incorporated, especially in modem control rooms.
During recent years, it has become increasingly clear from "real-life" studies in
complex production and transport industries that professional highly skilled troubleshooters
can develop effective general purpose search strategies for locating and
dealing with faults and, most importantly, with new and not previously experienced
faults. This research has indicated that means for training of these general diagnostic
abilities can be developed. In addition, other work has dealt with the problem of
observing and analyzing operator behaviour in coping with disturbances. The
NKA/LIT-4 project has continued these efforts in studying methods for training
diagnostic skills as well as for observing and testing operator behaviour on training
simulators.
