A model for the management of a tram fleet

The maintenance of transport vehicles represents an important aspect of the operating costs of a local public transport company (TPL). This work analyses the programmed and repair maintenance procedures of a recently operating tram fleet.By careful technical and economic analysis of data from the machine shops, two models have been developed with the aim of forecasting time and operating costs of maintaining rolling stock, using the parameters of Reliability, Availability, and Maintainability (RAM). It is a probabilistic model for the management of breakdowns on the tramline and for the analysis of shop maintenance operations, and a model for the calculation of Life Cycle Cost (LCC). The procedure has been applied to a TPL company obtaining satisfactory results in line with financial budgets and consistent with the purchasing specifications.
