【 摘 要 】

The paper describes the peculiarities of multiple indicators of reliability of automated control systems. Along with the dependability considered an indicator such as the dangers of system failure. Showing particular account of the reliability of the automated control systems when considering their versatility. We study methods of lowering the probability of dangerous failure. Such method could be the reallocation of resources needed for inclusion of backup elements from module carrying a low danger to modules, carrying high-dangerous failures. Another method is identification of least important functions and transfer resources, needed for inclusion of backup from them to most important and dangerous modules, and preventing threats by blocking modules.
