Characterization of probabilistic faults diagnostic models

This paper suggests a characterization of probability-based search models describing various fault diagnostics processes, which are widely used in the current practice of complex computer systems and networks systems maintenance and service. The characterization is performed in terms of some tuples including: characteristics of fault models, localization procedures, cost functions, and other factors. Such characterization (and an induced classification) can be used for a rational choice of search algorithms at earlier system design stages, for development of strategies of possible fault localization during the target systems maintenance and service. Special attention is paid to the teaching the related topics in fault diagnostics of computer systems and networks.
