Ключевые слова: сложная техническая система, надежность, безопасность, коэффициент готовности, интенсивность отказов, вероятность опасного отказа
Аннотация. В статье рассмотрены системы железнодорожной автоматики и телемеханики как сложные технические системы, состоящие из совокупности функциональных блоков. Последние представляют собой систему с наличием или отсутствием восстановления и резервирования. На основе теории марковских случайных процессов разработаны математические модели функционирования блоков. Определены показатели надежности и безопасности системы в целом. Приведена методика построения сложной технической системы с требуемым уровнем надежности и безопасности.

Keywords: complex technical system, reliability, safety, availability function, availability factor, failure rate, prob-ability of a dangerous failure
Summary: Railway automation and telemechanics systems are considered as complex technical systems consisting of a set of functional blocks. Each functional block is restorable or non-restorable system with or without redundancy. On the basis of the theory of Markov processes mathematical models of blocks’ functioning are developed. The parameters of reliability and safety of the system as a whole are determined. The method of building the complex technical system with the required level of reliability and safety is given.
