Common Sense Reasoning in Diagnostic Systems - Efficient Decision Support Systems: Practice and Challenges from Current to Future - page 107

Further, we shall view the structure of a case library for RT IDSS on the basis of non-classical
logics for monitoring and control of complex objects like power units.
The case library for RT IDSS should join in itself the cases concerning a particular subsystem
of a complex object, and also contain the information on each parameter which is used for
the description of cases (parameter type and range). Besides, the case library should include
such adjustments, as:
 the significance of parameter;
 a threshold value of similarity;
 a value which limits quantity of considered cases.
It is necessary to emphasize, that the case library can be formed on the basis of:
 the experience, accumulated by the expert;

 the analysis of the system archive;

 the analysis of emergencies;

 operative instructions;

 technological requirements.
