| Popis: | This paper presents the results of the investigations of the trends of average costs incurred by manufacturers of public transport vehicles following the elimination of unplanned malfunctions under warranty. The developed research methodology utilizes a method of analysis of variance for validation of the following two hypotheses. The first hypothesis relates to the examination of the significance of differences between average costs of the elimination of a malfunction and the other relates to the examination of the significance of differences in the average number of malfunctions per single vehicle in the highlighted periods of operation. The hypotheses were conducted based on the operation data relating to the malfunctions of a fleet of trams used by a city transport operator. |
