Abstract

This scientific paper deals with analysis of the reliability indices of the technical systems, which consist of a set of different and independent restorable elements with the given failure rates, repair rates and reliability structure. An offered by the authors combinatorial method for calculation of the reliability indices of restorable technical systems with arbitrary reliability structure is discussed. The obtained by the authors formulas for calculation of the stationary availability factor, mean time to failure and mean time to repair are also presented. Finally, an example of calculation of the reliability indices for the technical system with the bridge reliability structure is also given.
