Etapy użytkowania pojazdów ze względu na efektywność eksploatacyjną na przykładzie autobusów miejskich

Celem artykułu jest porównanie efektywności eksploatacyjnej autobusów miejskich w różnych etapach okresu użytkowania. Przeprowadzono badania gotowości technicznej, kosztów napraw i przychodów w czasie sześciu lat eksploatacji na przykładzie dwóch popularnych marek autobusów (krajowych i importowanych). Na podstawie tych badań wyznaczono charakterystykę efektywności eksploatacyjnej autobusów. Wykazano, że czas użytkowania wpływa znacząco na efektywność eksploatacji. Rozpatrzono podział całkowitego okresu użytkowania pojazdów na okres gwarancyjny i pogwarancyjny oraz wprowadzono nowy podział na „okres pełnej przydatności eksploatacyjnej” i „okres ograniczonej przydatności eksploatacyjnej”. Ten nowy podział czasu użytkowania na etapy umożliwia wyznaczenie najbardziej racjonalnej granicy użytkowania pojazdu do chwili wycofania go z eksploatacji. Może być także wykorzystany przy wyborze marki pojazdu w ramach programu odnowy lub rozbudowy floty.

Stages of operating vehicles with respect to operational efficiency using city buses as an example

 

The aim of the article is to compare the operational efficiency of the city buses in various stages of their operational life. Technical readiness tests, repair costs and revenues during the six years of operation were conducted using two popular bus makes as an example (domestic and imported). Based on these tests, the characteristics of the operational efficiency of buses was determined. It has been shown that the service life has a significant effect on the operational efficiency. The division of the total operational period of the vehicle into the warranty and post-warranty period was considered and a new division was introduced, of the „period of full operational usefulness” and “period of limited operational usefulness”. This new division of service life into stages makes it possible to determine the most reasonable limit of the vehicle usage until it is taken out of service. It can also be used when choosing a vehicle make as part of a fleet renewal or extension program.

 

Operational risk assessment model for city buses

The development of public transport systems presently focuses on sustainability. In this situation, the issue of user (passenger) migration has become important to the transport company as a service provider. This paper presents an integrated model of the operational risk of vehicle incapacity, including the following: costs of incidental repairs, costs of unplanned downtime and costs resulting from potential user migration. The paper presents the results of operational research on buses of two makes over a period of 6 years, in the mileage range of 0420 000 km. The authors have determined the risk as a regression function of operational mileage to estimate the optimum life cycle. The quality of the vehicle was assessed using the criterion of the maximum cost of the operational incapacity risk being equal to the current residual value of the vehicle. The research results confirmed the suitability of the integrated risk model for a comparison of vehicle makes and assessment of their reasonably foreseeable life cycle in a balanced carrier-vehicle-user system.
