THE ASYMPTOTIC EXPONENTIAL FAILURE LAW FOR GENERAL REDUNDANT REPAIRABLE SYSTEM AND ITS APPLICATIONS

The asymptotic exponential failure law for an arbitrary redundant repairable system is quite generally established by decreasing the unit unavailabilities to O, without assuming, among other things, the exponentiality of life/repair distributions of the units. Using this fact, the system reliability can easily be approximated well by the exponential function, even if the unit unavailabilities are of small but positive values. The error of this approximation is successfully evaluated. Moreover, the asymptotic system repair-time distribution is also derived. The usefulness of these results is exemplified by several numerical examples and by practical reliability evaluation of a major subsystem of MARS 105, JNR's computerized seat reservation system.
