| Abstract: | A reliability analysis of the cold nonmaintained n component redundant repairable systems is presented. When the component used lifetime and the repaired time, the switch used lifetime and repaired time are axponential distributions. Each component after repair is as good as new, whenever n is given. We can obtain the exact formulas of the Laplace transformation of reliability R(t) and the mean lime to failure t MTTFF . Finally for n=2 and 6, the results of reliability and t MTTFF of corresponding system are presented. |
