Analysis of application of stability indicators in the development of an expert system for detecting failure precursors

Tikhonov Martin Robertovich, Tikhonov Robert Robertovich

This article discusses and analyzes stability indicators and the possibility of their application in expert systems for detecting failure precursors. The indicators are based on generally accepted and widely described economic indicators and are focused on application in various organizations and activities. The indicators are divided into three groups depending on the method of obtaining their values, namely by: comparing the values of generally accepted economic indicators; comparing the rate of change of generally accepted economic indicators (their first derivatives); comparing the acceleration of change in generally accepted economic indicators (their second derivatives). The possibility of processing these indicators using conventional fuzzy inference models is analyzed.

Keywords:stability indicators, expert system, artificial intelligence, automated control system, failure precursors.
