Reliability model of the railway transportation system with respect to hazard states

Abstract

In this paper, the authors' research work is focused on modeling of railway transportation system's reliability and safety with respect to hazards. The paper begins with an introduction related to a literature review on system reliability and safety modeling and reliability models. A state-transition model was proposed. Defining states in terms of railway transportation system is a complex issue, therefore the state classification into availability and failure is not sufficient. In addition to the technical effects associated with incorrect operation of system components, traffic disruptions, as consequences of events are important, especially in case of railway transportation system. The Markov model was built, is described in relation to the parameters above. The paper ends with validation of the model, conclusions of the analysis, dealing with applicability of the model to solve problems for the real system and a summary with prospects for further research.
