| Abstract: |
In this paper the Wiener process with linear drift is proposed as a degradation model for the railway substructure. The model is based on the empirical data describing loss of tracks quality over the distance of one kilometre. The impact of explanatory variables on tracks degradation is investigated. The Bayesian framework is applied to examine uncertainty in the development of degradation for different sections along the tracks. |
