A process involves drilling holes that are supposed to be 3 inches deep. If it is known that the quality cost of a hole drilled 2.95 inches (within the spec limit) deep is $5.00, what is Taguchi's quality loss function for this process? A. L=36D2 B. L=3 D2 C. L=6 D2 D. L=2000 D E. L=2500 D2 In the above question, what is the Taguchi loss if an item has a diameter of 2.90cm? A. 20 B. 25 C. 0.36 D. 200 E. 250 A foundry produces circular utility access hatches (manhole covers). Currently, 120 covers are produced in a 10-hour shift. If labor productivity decreases by 20% due to a process change, it would then be: A. 95 covers/hr. B. 11.8 Covers/hr. C. 144 covers'hr. D. 9.6 covers/hr. E. 14.4 covers/hr. The cost of a failed part is $500 and the part's reliability is 95%. The demand of the parts is 100 units. We have the following three options: (i) Spend $1,000 to increase the reliability to 98%; (ii) Spend $2,000 to install a backup component with reliability is 95%.; (iii) Do nothing. What option should we choose? A. Choose Option (i) B. Choose Option (ii) C. Choose Option (iii)
