Application of the Bayesian approach in an expert’s system for diagnostic fault in computing engineering

Abstract

The problem of increasing the efficiency of maintenance and repair of computer equipment is solved by applying the method of probability theory in expert systems. An expert system is a set of programs that accumulates the knowledge of specialists in a specific subject area and replicates this empirical experience for consultations of less qualified specialists. A probabilistic analysis method of equipment operation is used in the expert system under development for diagnosing and preventing computer malfunctions, is used. This article provides detailed description of the expert system, diagnosing the causes of computer malfunctions, provides a structural diagram of the system, rules and facts of work are generated. Based on the well-known Bayesian formula, this article describes a method for using fault information to clarify initial probabilities.
