A change of complex economic indicators of passenger rolling stock deterioration
Abstract
Various criteria describing the state of a locomotive from various perspectives can be used to assess its performance. Some complex or integrated criteria reflecting a general state of Diesel locomotives can also be used. an integrated performance indicator characterizing the locomotive performance is expressed by the following functional relationship. The analysis of the available methods for complex evaluation of the locomotive condition has shown that overall performance of the locomotive can be described by a dimensionless indicator.
