Compute reliability for B1, B2 in series = B’
Compute reliability for B3, B4 in series = B"
Compute reliability for B5, B6 in series--B"
Compute reliability for B7, B8 in series = B
TM
Then shown in Fig. 4.12
The further reduction for Fig. 4.12 requires one to:
Compute reliability for B’ and B" in parallel = B(1)
Compute reliability for B" and B TM in parallel = B(2)
The results in Fig. 4.13
Figure 4.13 can be simplified further to:
Compute reliability for A’, B(1), C1 in series =A(1)
Compute reliability for A", B(2), C2 in series = A(2)
Then in Fig. 4.14 the results are
