Abstract : This 'paper presents the analysis of two non-identical
unlts-t and 2. Unlr-t
gets priority in operation as well as .in
repair.
unu-: stops working in any of the
two ways : (i) When it tails
totally (ii) when its operation come to standstill for some time due to an external
cause. In case (ii) the unit-t becomes. down temporarily
for ome time and starts
functioning again as soon as the
external cause disappears. The system· failure occurs only when both the units enter into total failure mode. The joint distribution of failure and repair times of unit-t
is taken to, be bivariate of failure
and repair times of unit- 1 ls taken to
be bivariate exponential
Key Words : Prlority unit system, correlated failure, repair times.
