EVALUATION OF THE VEHICLE REPAIR SUBSYSTEM WITH MARKOV MODELS

Abstract

Analysis and evaluation of repair subsystem in the transport system is extremely important. It has a direct impact on the quality of performed tasks and the readiness level of surveyed organization. It also enables to identify factors that have a negative impact on the repair process, its duration and quality. These include e.g. waiting times for spare parts, for specialists (mechanics) or free repair stations (channels), as well as availability of equipment or tools necessary for implementation of renewal procedures. The level of training, knowledge and experience of mechanics, which can be key to the success of planned repairs, is also extremely important.

This article presents an analysis of the example of repair subsystem. The Markov models were used for diagnostics, which enabled to determine the probability limit values of duration of the operating states distinguished in this subsystem and, on this basis, to determine the imperfections of implemented processes and possibility of their improvement.
