Consider the seven-component system shown in given Figure. The reliabilities of the components are as follows: RA = 0.96, RB= 0.92, RC=0.94, RD = 0.89, RE = 0.95, RF=0.88, RG =0.90.
Find the reliability of the system. If you had a choice of improving system reliability by modifying any two components, how would you proceed?
