MODELING OF TRACK TECHNICAL STATE WHEN OPERATING TIME IN TERMS OF TONNAGE IS HIGHER THAN NORMATIVE

Abstract

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT In the current provision on the system of track management of JSC Russian Railways, the existing criteria for assignment of main types of repair of the track do not allow making unequivocal decisions on timing of future repairs. The article discusses a methodology and model that helps to justify the time of overhaul in order to actualize the application of the specified criteria and extend the period of operation of the track in the zone of track sections where tonnage of transported goods has exceeded the standard cumulated value, requiring thus maintenece works (called operating time in terms of tonnage). This methodology is based on forecasting of failures of its elements using the developed model. Keywords: railway, track, mean tonnage value, mean time between overhauls, residual resource, overhaul, management decision, mathematical model.
