Evaluation of the effectiveness of repairs carried out of centres of the road transport

The transport systems and especially the means of transport are the sources of life and health hazard and the natural environment pollution. Exploitation process influence on the elements of the technical objects and decrease the values of the important features of them. This is the mechanism of the damage process. Wear factors could be divided into two groups. One of them are the factors results from the bed operation of the object operators and the second group consists of the factors results from the environment interaction. The damages are the events which are very important from the reliability point of view because are the reason of the partly or full disability. In the paper the damage is defined as the exceeding the acceptable thresholds of the technical object important features.
