Research on effectiveness of transport means operational reliability and efficiency repairs

Systems of transport means operational use are such systems whose main goal is to carry out transport tasks on an assigned territory. In each transport system assurance of the used transport means availability, viewed as the object capability to accomplish the transport task, is of great importance. A certain number of damages results from natural wear of transport means elements which is a natural phenomenon, whereas other damages can be caused by in effective repair of the previous damage. In this way, within a short time, there occur the so called repetitive damages to the repaired element. This reflects improper organization of repairs, poor skills of the maintenance workers, limitations connected with wrong diagnosing before and after the repair. Damages occurring during means of transport operation involve bearing considerable costs while assuring the transport means operational reliability, as well as covering the losses connected with impossibility to accomplish the transport task. Finding out the causes of in effective repairs would reduce the costs that a transport company has to bear to provide efficient operation of means of transport. Times of resultant repairs and being unftt for use have been analyzed, as well as costs of repairs, spare parts, maintenance and operation.
