Abstract

The purpose of this paper was to present a failure rate and maintenance cost comparison for two types of city transport buses. The paper presents in detail a case study of well known bus brands used at Municipal Transport Company in Lublin. A failure index of all functional and constructional systems of the vehicles and their technical availability with regards to calendar time was determined. The paper also presents analysis of the factors related to maintenance costs of buses, including costs of fluids, repair costs and maintenance service. It has been demonstrated, that both analyzed buses generate similar maintenance costs, while their failures and technical availability differ significantly in operational practice. These differences are particularly evident in relation to the cumulative costs of repairs.

Abstract

The article presents the results of the reliability tests of three makes of trucks. They used samples of 30 vehicles of each make. The vehicles were used by transport companies on a rental basis. The analysis omitted defects of the body-work of the vehicles as the component unrelated to a particular make. The first part of the analysis characterized operating process in respect to mileages and operating time. Then the analysis of the reliability of vehicles and their components was conducted taking into account the mileages till the first recorded defect and separately inter-repair periods’ mileages. The analyses presented are part of a larger work, which aims to develop a method for evaluating the operational quality of trucks from the point of view of the owner of the rental vehicles.

Abstract

The maritime transport is particularly exposed to danger due to the environment of its operations. These are the threat dependent and independent of human e.g. environmental, safety health and life of humans or belongings. In spite of attempts to limit the risk of danger, it is impossible to completely eliminate it. The article presents some aspects of the state of transportation safety in the Baltic Sea from Statistical Yearbook of Maritime Economy and Helcom as well as attempt the undertaken to analyses the security state of this sea area in 2009 to 2015.
