Abstract:
The analysis of the reliability and availability of the data transmission system within the integral railway system is realized through the modeling of the system, i.e. its conditions and their connections. According to the defined measure of safety of the International union of railways (UIC) i.e. its committee ORE, defined by recommendations A 158 and A 124/RP, based on previous experience and the achieved level of technical development, we can estimate an acceptable value for the probabilities of certain conditions of the integral railway system and data transmission system. In the paper, the reliability and availability analysis was modeled using the Markov model for data transmission in the railway system with four conditions, for: correct system condition, presence of disturbances in the system, illegal (dangerous) system condition and system blocking condition. The validity for the application of process development modeling the reliability and availability of data transmission in the railway system will contribute to reducing the risk of inadmissible (dangerous) failures, improving maintenance planning and spare parts planning, moving from maintenance by time to maintenance by condition and reducing exploitation costs.
