SOLVED PROBLEM 17.1 SOLUTION The semiconductor used in the Sullivan Wrist Calculator Semiconductor reliability, R = R XR, XR; XR, XR has five circuits, each of which has its own reliability rate. =(.907.95)(-98).90).99) Component 1 has a reliability of 90: component 2.95; com- = .7466 ponent 3,98; component 4,90; and component 5.99. What is the reliability of one semiconductor? SOLVED PROBLEM 17.2 A recent engineering change at Sullivan Wrist Calculator places a backup component in each of the two least reliable transistor circuits. The new circuits will look like the following: R Rg RE .90 -90 .98 90 99 .95 .90 What is the reliability of the new system? SOLUTION Reliability = [.9 + (1 - 9) *.9] .95 x 98 x 1.9+ (1 - 9).9] *.99 = [.9+.09] x 95 x 98 x [.9+.09) X 99 = 99 x 95 x 98 x 99 x 99 =.903 Problems 17.1-17.17 relate to Reliability 17.1 The Beta II computer's electronic processing unit contains 50 components in series. The average reliability of each component is 99.0%. Using Figure 17.2, determine the overall reliability of the processing unit. 390 Assignm
