Question: How would the reliability of the system in Exercise 4.4.23 change if the reliability of unit 3 were changed from 0.93 to 0.96? What change if the reliability of unit 2 were changed from 0.90 to 0.95 (with unit 3 unchanged)?
Exercise: A system has eight components with respective probabilities
0:96 0:90 0:93 0:82 0:85 0:97 0:88 0:80
Units 1 and 2 form a parallel subsytem in series with unit 3 and a three of five combination of units 4 through 8. What is the reliability of the complete system?
