Analytical Methods of Calculating the Lifetime Distribution for Some Models of Standby Redundant Systems (Published)
In present day technology, reliability of equipment’s is increased by employing the method of standby systems, that is, the introduction of extra units. The purpose of the supplementary units is to take over operation if the basic units break down. Moreover, to increase the effectiveness of standby systems, units that have failed are repaired. In this paper the reliability function and the mean lifetime are obtained for the cases of loaded, nonleaded and lightly loaded systems with and without renewal.Moreover, the effectiveness of repair is calculated for some distributions for different numbers of main units.
