Tg. Pham et N. Turkkan, RELIABILITY OF A STANDBY SYSTEM WITH BETA-DISTRIBUTED COMPONENT LIVES, IEEE transactions on reliability, 43(1), 1994, pp. 71-75
The exact distribution of the sum of 2 independent beta variables is p
resented. It is applied to a standby system with beta-distributed comp
onent lives and permits the calculation of its exact reliability when
the exact parameters-values are known. It appreciably improves the cur
rent approximate method.
