PURPOSE: The calculating method of the system defection probability of the large size safety facility using SDP calculating method of major minimum group fold combination generations adds the simple calculation. In that way the system defection probability can be predicted accurately. CONSTITUTION: A minimum group fold combination generations calculated from the number of failures neck are read from database(S10). A minimum group fold combination generations are arranged to the individual size(S20). Arranged minimum group fold combination generations separate from the sub-group of N+1(S30).
