R. 14, nr 3

In this article considered safety and reliability question on railway transport. In diagrams seen that too much failures depends on operator factor in train and maneuver work. That is why came an idea to make mathematical model, including operator factor. It means that in system can be two different failure types - "technical" and "man" factor. Using this model is possible to find out system with optimal parameters.

nr 6

It is discussed validity of the dangerous and safety failures concept by automation and remote control systems safety estimation. There is estimated error in automation and remote control systems calculation on safety levels that is based on the unsafe failures. It is proposed new decision to develop automation and remote control systems safety models that is based on the “unsafe” elements conception. It is developed three automation and remote control systems Markov models for systems different configurations. It is developed and explored computer models, obtained automation and remote control systems safety indicators numerical values: - automation and remote control systems unsafe conditions probability, - safety coefficient, - probability of systems safe work.
