Operational Availability of Railway Dispatch Communication System

Abstract

In the article, issues on assessment of operational availability of transport telematic systems are presented. Digital railway dispatch communication system has been selected for analysis and assessment. Presented has been the model of the system’s exploitation process, including its functional structure. Markov and semi-Markov processes have been used for modelling of the exploitation process. The conclusion contains the example of a computation of operational availability of the digital railway dispatch communication system.
