SWS1000L
1. Calculated values of MTBF
MODEL : SWS1000L-5
1. Calculating Method
Calculated based on part count reliability projection of JEITA (RCR-9102).
Individual failure rates λ
G
is given to each part and MTBF is calculated by the count of each par
t
Formula :
MTBF =
λ
equip
= X 10
6
(HOURS)
n
Σ N
i
(
λ
G
π
Q
)
i
i=1
where :
λ
equip
= Total Equipment Failure Rate ( Failure / 10
6
Hours )
λ
G
= Generic Failure Rate For The ith Generic Part ( Failure / 10
6
Hours )
N
i
= Quantity of ith Generic Part
n = Number of Different Generic Part Categories
π
Q
= Generic Quality Factor for the ith Generic Part (
π
Q
= 1 )
2. MTBF Values
G
F
: (Ground, Fixed)
MTBF = 121,485 (Hours)
However MTBF calculation for fan isn't included.
