Computerization of rail vehicles maintenance systems

In the paper the problems of rail vehicle maintenance are solved in three levels; the theory of systems is utilised for the analysis of a transport means with the output on the maintenance quality, the mathematical model of maintenance process optimisation which can be practically utilised by use of computer, and an example of real existing vehicles maintenance system modelled by use of commercially available software. The possibilities of computer processing of statistical data of transport means reliability and failures are analysed. Possibilities of maintenance works combinations and variations are studied by use of software for project management.
