Uticaj vremena nastajanja otkaza na operativnu gotovost vozila u organizovanim voznim parkovima

Abstract

Svi problemi vezani, kako za potpune tako i za delimične otkaze, navode na činjenicu da vremena nastajanja otkaza veoma utiču na gotovost voznog parka i organizaciju sistema održavanja. To je posebno važno i u odnosu na frekvenciju korišćenja vozila i prevoz putnika (kada su špicevi u prevozu putnika). Otkaz jeste slučajan događaj koji se najčešće ne može blagovremeno predvideti. Međutim, imajući na umu raspored i intenzitet korišćenja vozila u toku jednog dana, kao i statističke podatke o prijavama otkaza za neki duži vremenski period, može se pretpostaviti gustina pojave otkaza, odnosno, u kom periodu radnog dana su otkazi, prema statističkim podacima, verovatniji.

The failure is indeed an accidental event, which in most cases can not be foreseen in due time. However, keeping in mind the timetable and intensity of motor vehicle utilization in the course of a day, as well as the statistical data of failure reports for a longer period of time, the density of failure occurrence can be predicted, which means that, according to statistical data, it can be assumed in which periods of time during a working day the failures are more probable to occur. The data obtained on the density of occurrence of failures have an exceptional importance for planning first of all within the organization of the maintenance system as well as in the allocation of vehicles within the motor vehicle fleet, which is presented in this paper.
