MGL (Multiple Greek Letter) Model
Input Parameters:
Unavailability of CCF events:
Where:
ρi = The conditional probability that the cause of failure of a specific component will be shared by at least i additional components.
The FTA module accepts only β, 
, and 
as inputs. If the number of components (n) is more than 4, ρi = 0 is used for i > 4. If n < 4, only the appropriate parameters are used. For example, if n ,= 3, only β and 
are used.
