Methods for differentiating technical conditions of locomotives

Abstract
The problem of differentiating between the technical conditions (TC) of locomotives is examined. The differentiating and identification of technical states constitute one of the primary tools of technical diagnostics, based on the theory of pattern recognition. Examples of technical conditions classification (patterns) drawn from the regulatory and technical framework in the field of reliability are presented, alongside the examples of technical conditions for railway signals and interlocking devices, an example of TC from the energy sector, and types of risk groups (conditions) of locomotive crew members are provided. The presented comparison reveals that more detailed methods for distinguishing TC exist for individual locomotive components and assemblies than for the entire locomotive, despite its complexity and the principle of superadditivity (a system is more complex than the sum of its parts).
The effectiveness of the current methodology for classifying locomotives into risk groups is evaluated. Using the existing methods of distribution, due to the large number of high-risk locomotives, the repair complex will not be able to perform the specified amount of work due to the availability of maintenance plans and unplanned repairs.
In order to improve the operation of locomotives, several new methods for classifying their operational characteristics are proposed: using a naive Bayesian classifier based on reliability indicators, assessing the deviation of locomotive operating (working) parameters from the standard, and a combined method.
