Abstract


The aim of all companies is to increase their profitability and it is no different for the railway environment. Possible steps toward obtaining this goal includes reducing costs, increasing productivity and efficiency. One focus area within the railway technical environment that can facilitate in obtaining these goals is maintenance. Even though conventional strategies such as corrective and preventive maintenance have proven to be lifesaving in some cases, it does not always adhere to the cost saving and process efficiency drives by companies. A new strategy of predictive maintenance is being investigated which is based on forecasting of system degradation through a prognostic process by using condition monitoring data. The objective of this paper is to propose a prognostic model which will be used for predicting the most cost and time effective maintenance schedule for a railway wagon based on the condition of its bogies, wheels, bearings and brake blocks.
