How can the overall stability of a system be determined based on the reliability indicators of its individual components?

The overall system reliability is determined based on the reliability of its individual components, using methods of reliability theory and probabilistic modeling. If the failure-free probability of each element is known, then for a series system, the total reliability is the product of the reliabilities of all elements:

[ R_{system} = \prod_{i=1}^n R_i ]

where (R_i) is the reliability of the i-th element.

For parallel systems, where failure of all elements leads to system failure, the total reliability is calculated as:

[ R_{system} = 1 - \prod_{i=1}^n (1 - R_i) ]

Thus, by analyzing the system structure (series, parallel, or mixed) and component reliabilities, the overall system robustness can be determined.
