Common Sense Reasoning in Diagnostic Systems - Efficient Decision Support Systems: Practice and Challenges from Current to Future - page 118

From table 1 one can see that the greatest efficiency of current measurement point choosing
has the heuristic method based on the knowledge about coincided assumptions of the
inconsistent environments SCAIEH.
8. Conclusion
The method of reasoning by analogy on the basis of structural analogy was considered from
the aspect of its application in modern IDSS, in particular, for a solution of problems of real-
time diagnostics and forecasting. The example of the algorithm for solution search on the
basis of analogy of properties that takes into account the context was proposed. This
algorithm uses a modified structure of analogy that is capable of taking into account not
one property (as in the base algorithm), but a set of properties. These properties determine
the original context of analogy and transfer from the source to the receiver only those facts
that are relevant in the context of the constructed analogy.
The method of case-based reasoning was considered from the aspect of its application in
modern IDSS and RT IDSS, in particular, for a solution of problems of real-time diagnostics
and forecasting. The CBR-cycle is considered and its modification for application in RT IDSS
is offered. The k-nearest neighbor algorithm for definition of similarity degree of the current
situation with cases from case library is described. The structure of case library for RT IDSS
is proposed. The proposed method of case-based reasoning was implemented in Borland
C++ Builder 6.0 for Windows 7/NT/XP. The main functional components of the
implemented tool (Case Libraries Constructor - CLC) are specified.
The possibility of application of analogous reasoning in case-based reasoning is underlined.
We also note that the elements of case-based reasoning may be used successfully in analogy-
based reasoning methods; i.e., these methods successfully complement each other and their
integration in IDSS is very promising.
The heuristic methods of finding the best current measurement point based on
environments of device components work predictions are presented.
Practical experiments have confirmed the greatest efficiency of current measurement point
choosing for the heuristic method based on the knowledge about coincided assumptions of
the inconsistent environments SCAIEH.
Advantages of heuristic methods of the best current measurement point choosing is the
simplicity of evaluations and lack of necessity to take into consideration the internal
structure interconnections between components of the device.
The presented methods and tools were applied at implementation of a prototype of RT IDSS
on the basis of non-classical logics for monitoring and control of complex objects like power
units and electronic circuits.
