| Abstract [eng] |
In this work the reliability of the emergency systems is analysed. Some equipment in various chemical and industrial factories, power plants and similar corporations are ending their life. The possibility to extend it gives great importance to the reliability investigation. Since many of that type of systems is constantly in standby mode and runs only on demand, i.e. the emergence of certain conditions, the availability of the elements must be extremely high. The aim of the work is to investigate statistical models for system reliability control and the possibility to change the testing intervals of devices in such a way, that the safety level of whole system would not be decreased. The investigation is performed by modelling failure rate changes of system elements concerning ageing. |
