The methods of definition of the quantitative evaluation of internal safety of communication systems on the basis of the railway transport

摘要

The paper contains methods of the quantitative evaluation of internal safety of communication systems on the railway transport with a glance to the influence different factors: internal and external. The calculation of safety parameters was made by methods of Markov chains, probabilistic mathematical modeling. The required level of the safety could be provided by defining of the rational service periodicity of communication systems on the railway transport.
