1. Reliability Manuplex, Inc. plans to set up a complex manufacturing process which incorporates three types of machines. Because of the nature of the process, machines frequently fall out of adjustment and must be repaired. To keep the system going, two machines are used at each stage; thus, if one fails, the other can be used while the first is repaired. The company is now checking three plans (see accompanying figure).
Plan A
Plan B.
Plan C.
A AThe reliabilities of the machines are as follows:
Machine Reliability
A 0.89
B 0.85
C 0.72
a. Analyze the system reliability of the three plans.
b. Which plan has the highest reliability?
